Claude Code Channels: Push New Competitor Posts Into a Live Session

EveryInfra — Sat, 07 Nov 2026 06:16:06 +0000

Claude Code channels let an MCP server push an event into a session that is already running, so Claude reacts without a prompt from you. They arrived as a research preview in version 2.1.80 on March 19, 2026, and 15 changelog entries have touched them since. We read the docs on November 7, 2026 and built a small channel server for one job. It watches three design-tool companies, Figma, Canva and Framer, on X, TikTok, YouTube and LinkedIn. It pushes only their new posts into the session.

Between 00:32 and 00:40 Singapore time on November 7, 2026, its first live round read 120 posts from 9 sources for $0.005004. The three LinkedIn pulls returned 503 and cost nothing. Polling hourly, the API bill tops out at $8.61 a month. Claude Code itself is not installed on our test machine, so the Claude Code side appears below as a configuration example. Every number about our API comes from a raw response we kept.

Key points

Channels are a research preview since 2.1.80 (March 19, 2026), and a channel you write yourself needs --dangerously-load-development-channels, and -p ignores that flag.

Hourly polling costs at most $8.61 a month for 12 sources, or $3.60 without the 3 LinkedIn sources, and failed calls cost nothing.

In one week, nine sources gave only 31 non-reply posts (4.4 a day); 18 of Canva's last 20 X posts were replies.

Estimate: reading raw rows every hour puts about 978,252 tokens a day into the model, while pushing only new posts puts in about 260.

If you read competitor news once a day, a scheduled task is enough; you do not need a channel.

What Claude Code channels are, according to the docs on November 7, 2026

Many guides about this feature date from launch week in March. Some of their claims are now out of date. So we read the official Claude Code pages and the changelog again on November 7, 2026. Each fact below comes from that reading. When the docs do not say something, we write "the docs do not say".

The docs define a channel as an MCP server that pushes events into a running Claude Code session. Claude can then react to things that happen while you are away from the terminal. A channel can also be two-way, like a chat bridge (Channels docs). Two words in that definition matter.

"Running" means that events arrive only while the session is open. For an always-on setup, the docs tell you to run Claude in a background process or a persistent terminal. "Push" is the gap that channels fill. A standard MCP server answers only when Claude queries it during a task.

The feature is still a research preview. The docs say that availability is rolling out gradually. They also say that the --channels flag syntax and the protocol contract can change. Neither --channels nor --dangerously-load-development-channels appears in claude --help during the preview, but both flags work (Channels docs, Research preview).

The feature first shipped in v2.1.80 on March 19, 2026. The changelog line reads "Added --channels (research preview)" (Claude Code changelog; v2.1.80 release on GitHub). One day later, v2.1.81 added permission relay, so a channel can forward tool approval prompts to your phone.

Item	What the docs say	Source, read on
Definition	An MCP server pushes events into a running session; one-way or two-way	Channels docs, Nov 7, 2026
Status	Research preview; flags and protocol can change; hidden from `claude --help`	Channels docs, Research preview
First version	v2.1.80, March 19, 2026	Changelog
Sign-in	claude.ai account or Console API key; not on Amazon Bedrock, Google Cloud Agent Platform, or Microsoft Foundry	Note at the top of the Channels docs
Individual plans	Pro, Max, and Ultra users without an organization skip org checks and opt in per session	Enterprise controls
Team and Enterprise	Off until an Owner enables it, or `channelsEnabled: true` in managed settings	Enterprise controls
Console orgs	Allowed by default with API key auth; orgs with managed settings set `channelsEnabled: true` (since v2.1.128)	Enterprise controls; changelog v2.1.128
Anthropic plugins	Telegram, Discord, iMessage, plus the fakechat demo; the plugins are Bun scripts	Supported channels
Your own channel	Not on the allowlist; test it with `--dangerously-load-development-channels server:<name>`	Channels reference
Minimum version	The docs give no single minimum; the feature exists from v2.1.80, and some relay behavior needs v2.1.211 or v2.1.234	Changelog; Channels reference

The sign-in row is the one that surprises teams. Channels are a feature of the Claude Code client, not of the model API. If your company reaches Claude through Bedrock, Google Cloud, or Foundry, the same Claude Code version has no channels. The Team and Enterprise row is the second trap. When an Owner has not turned the feature on, the MCP server still connects and its tools work. But pushed messages never reach the session, and a startup warning tells the user to ask an admin (Enable channels for your organization).

A scheduled task wakes the model at every interval. A channel lets a local server filter first and wakes the model only for new posts.

How an MCP server pushes a message into the session

To build your own channel, you need only the @modelcontextprotocol/sdk package and a Node.js-compatible runtime. Bun, Node, and Deno all work. The official plugins use Bun, but your channel does not have to (Channels reference, What you need). The server must do three things. It declares the claude/channel capability.

It emits notifications/claude/channel events. It connects over stdio. Claude Code starts the server as a subprocess and talks to it through standard input and output. This matches the stdio transport in the MCP specification. Messages are newline-delimited, stdout carries only valid MCP messages, and logs go to stderr (MCP specification, Transports).

A notification has two fields. content is the event body and becomes the text inside the <channel> tag. meta is optional. Each key becomes an attribute on the tag, which is useful for the platform name, the account, or a severity level.

The docs add one rule that is easy to miss: keys must contain only letters, digits, and underscores. A key with a hyphen is dropped without an error. Our first draft used new-count as a key. We changed it to new_count after we read that line.

The three sentences that matter most when you write a channel server are all in this section. Claude Code docs, Channels reference, screenshot taken Nov 7, 2026

Two more points in the same section shaped our design. First, Claude Code does not acknowledge notifications. The await on mcp.notification() resolves when the message is written to the transport, not when Claude has read it. If the session did not load your server as a channel, or a policy blocks it, the events are dropped. Your server gets no error. For a delivery check, the docs suggest that you track state in the server and expose a tool.

We did that with a read-only watch_status tool. Second, events queue in the session and arrive in order. Events that arrive while Claude is busy come together on the next turn. For competitor alerts, this is useful. If three companies post in the same hour, Claude sees all three at once and can compare them.

Which gap channels fill next to scheduled tasks, Remote Control, and plain MCP

Claude Code already has several ways to connect outside events to a session. The channel page and the Remote Control page each have a comparison table. We merged the rows that matter for competitor monitoring and added our own judgment in the last two columns.

Feature	Trigger	Runs on	Session must stay open	Wakes the model every time	Fit for competitor alerts
Plain MCP server	Claude queries it during a task	Local or remote	Yes	Only when Claude calls it	Only when you ask
`/loop` session task	Timer, 1 minute minimum	Your machine	Yes; expires after 7 days	Yes, a full prompt each time	Works, but spends tokens on empty polls
Desktop scheduled task	Timer, 1 hour minimum in the form	Your machine, awake	No	Yes	Good for a daily digest
Cloud scheduled task (routines)	Timer, 1 hour minimum	Anthropic cloud, fresh clone	No	Yes	Good for a weekly report
Remote Control	You, from phone or web	Your machine	Yes	When you type	Not built for this
Channel	An outside event	Your machine, CLI	Yes	Only when the server pushes	Works; no tokens on empty polls

The last two columns are the core of this article. All three scheduled options run a prompt at each interval. The model wakes up, calls a tool, reads the result, and usually decides that nothing changed. /loop can run every minute, and Desktop and cloud tasks can run every hour (scheduled tasks comparison).

A channel moves the "did anything change" check out of the model. The server pulls data on its own timer, removes duplicates by post ID, and sends a notification only when a new post exists. The cost is that the session must stay open, and the feature is a preview.

Several articles on our site cover the other cells of this table. Claude Code cloud tasks that read Reddit every night uses a cloud task for a daily pain-point digest. ChatGPT scheduled tasks as a demand radar shows the same idea in another product. Claude Code subagents for TikTok brand accounts explains how to split context when you pull many accounts at once.

GitHub Copilot MCP for a competitor weekly report lets a coding agent write a script once, and GitHub Actions runs it every week. This article differs in one way. The other setups check on a schedule. A channel tells you when something new exists, which suits days when you want to know fast but most hours are quiet.

A claude code mcp push server: the full code

The file below is the whole channel server, about one hundred lines of TypeScript for Bun. It does four things. It reads a watchlist. Every POLL_MINUTES minutes, it calls EveryInfra POST /api/v1/social once for each row. It compares the post IDs with a local seen.json file.

It sends one notifications/claude/channel event only when a post is new. We ran this code on our own machine, and the next sections show what it produced. The one step that we did not run is the attachment to a live Claude Code session, because this machine has no Claude Code CLI. That step is a configuration example.

await pollAll()
if (process.env.ONCE !== '1') setInterval(pollAll, POLL_MINUTES * 60_000)   // ONCE=1: one round, then stop (for testing)

Four choices in this code come from the docs and from our live calls. Each one prevents a real problem.

First, the first run records a baseline and pushes nothing. A new server starts with an empty seen.json. If it treated the first batch as new, the session would get dozens of old posts. Claude would then write reply ideas for posts from last quarter.

The official iMessage plugin uses the same idea. Its README says that the watermark starts at the newest row when the server boots. So old messages are not replayed after a restart (iMessage plugin README).

Second, the server removes duplicates by post ID, not by date. A date rule looks simpler: "anything newer than the last poll is new." In our tests, pinned posts, time zones, and late indexing made dates unreliable. The numbers are in Test 2 below. Each platform gives every post a unique ID, and all four capabilities return it in the id field (see response_fields in the catalog). The file keeps at most 500 IDs per source. At 20 rows per poll, that covers 25 polls.

Third, the instructions string says that post text is untrusted data, not instructions. Competitor posts are public, and anyone can write "ignore previous instructions" in a post. The Channels reference calls an ungated channel "a prompt injection vector". That warning is about chat channels, where you must check the sender. Our sender is our own server, but the text comes from public pages, so the same risk sits in a different place. We say so in the instructions, and we cut each post to 280 characters.

Fourth, logs go only to stderr. The MCP specification says that a stdio server may write only valid MCP messages to stdout. One stray console.log breaks the protocol. The troubleshooting part of the Channels reference also tells you to restart with --debug and read stderr in the debug log (Channels reference).

Attach it to Claude Code: configuration example

This section is a configuration example. We did not run it on our machine. The machine has the Claude desktop app but no Claude Code CLI, and channels work in CLI sessions. The comparison table on the Remote Control page lists where channels run as "Your machine (CLI)" (Remote Control docs). The three steps follow the webhook example in the official docs.

First, install the dependencies and write the watchlist. Each row is the body of one POST /api/v1/social request. Use the catalog for capability names and parameters.

mkdir competitor-watch && cd competitor-watch
bun add @modelcontextprotocol/sdk zod
cat > watchlist.json <<'EOF2'
[
  {"label": "figma",  "platform": "twitter",  "action": "user_posts",    "params": {"username": "figma", "limit": 20}},
  {"label": "figma",  "platform": "tiktok",   "action": "user_videos",   "params": {"username": "figma", "sort": "newest", "limit": 10}},
  {"label": "figma",  "platform": "youtube",  "action": "user_posts",    "params": {"url": "https://www.youtube.com/@Figma", "sort": "newest", "limit": 10}},
  {"label": "figma",  "platform": "linkedin", "action": "company_posts", "params": {"company": "figma", "limit": 10}}
]
EOF2

Next, register the server in .mcp.json at the project root. The key stays in an environment variable. Claude Code expands ${VAR} references in .mcp.json and passes the value to the subprocess. So the key is in no file (MCP docs, environment variable expansion).

{
  "mcpServers": {
    "competitor-watch": {
      "command": "bun",
      "args": ["./competitor-watch.ts"],
      "env": { "EVERYINFRA_API_KEY": "${EVERYINFRA_API_KEY}", "POLL_MINUTES": "60" }
    }
  }
}

Last, start Claude Code with the development flag. During the preview, your own channel is not on the allowlist, so you must use --dangerously-load-development-channels. A full-screen warning appears first. Select "I am using this for local development". The first time you use a new server in a project, Claude Code also asks for consent for the .mcp.json server. A dim notice below the banner then confirms that messages from the server go directly into this session (Channels reference, Test it).

export EVERYINFRA_API_KEY=...        # a key from the EveryInfra console
claude --dangerously-load-development-channels server:competitor-watch

Two traps are worth knowing in advance. The first is non-interactive mode. The development flag works only in an interactive session. With -p or through the Agent SDK, Claude Code ignores the flag and the channel does not register. So during the preview, you cannot run claude -p as a daemon for this. Use an interactive session in a persistent terminal such as tmux or screen.

The second trap is the MCP client runtime. Claude Code now has two MCP client runtimes, v1 and v2. The v2 runtime asks stdio servers for protocol revision 2026-07-28. The docs say that a channel server on that revision cannot deliver channel messages. So Claude Code does not register it as a channel (MCP docs, Push messages with channels).

The @modelcontextprotocol/sdk package that we installed is version 1.32.2, published on npm on October 23, 2026 (npm package page). Its newest protocol is 2025-11-25, so it stays on the earlier handshake. The new 2.0 SDK uses a different package name, @modelcontextprotocol/server (TypeScript SDK v2 docs). If you build on it, set MCP_PROTOCOL_NEGOTIATION=legacy as the docs describe.

Test 1: the first pull, source by source

We ran the code above with ONCE=1, so it pulled one round and stopped. We added one more switch, RAW_DIR, to keep every raw response for audit, with wallet fields removed. A small stdio test client stood in for Claude Code. It started the server the way Claude Code does, completed the MCP handshake, listed the tools and logged every notifications/claude/channel message to a file. The handshake matched the docs: the server declared {"experimental":{"claude/channel":{}},"tools":{}}, and a dry run with an empty watchlist finished the handshake in 60 ms.

The first attempt did not go well, and we report it as it happened. Between 00:16 and 00:29 Singapore time, we sent 15 requests. Thirteen returned 503 and two returned 429, and none was charged. Each 503 carried retry_after: 60.

Other capabilities returned 503 in the same window, so the API itself was down, not our key. A probe at 00:31:51 Singapore time returned 200, and we started the real run. This is why the server retries once on retry_after and then waits for the next round. A resident channel must survive an outage, and it must never read an error as "no new posts".

The real first round ran from 00:32:24 to 00:40:04 Singapore time. The server pulled 12 sources one by one, with a 7-second gap to stay under 10 requests per minute. Times include queueing and retry waits.

Source	Result	Rows	Seconds	Charged (USD)
X · Figma / Canva / Framer	200	20 each	11.5 / 11.4 / 19.9	0.000556 each
TikTok · Figma / Canva / Framer	200	10 each	27.6 / 37.2 / 42.5	0.000556 each
YouTube · Figma / Canva / Framer	200	10 each	13.6 / 8.5 / 14.7	0.000556 each
LinkedIn · Figma / Canva / Framer	503, retried once, 503 again	0	about 64.4 each	0, refunded
Total	9 succeeded, 3 failed	120	460	0.005004

X and YouTube came back in under 20 seconds. TikTok took two to three times longer, up to 42.5 seconds for Framer. The session never waits for this, because the pull runs inside the server. But it sets a floor on the poll interval: one round of 12 sources takes seven to eight minutes.

Polling more often than every 15 minutes buys nothing. LinkedIn company_posts returned 503 all night. All three failures show request_failed_refunded in the billing block.

The nine successful pulls returned 120 posts and 163,042 bytes of raw JSON. Each X source was 23.5 to 26.9 KB, each TikTok source 21.7 to 23.5 KB, and each YouTube source about 6.4 KB. We use these byte counts in the cost section.

Test 2: why the server dedups by ID and drops replies

The first round showed three patterns. A naive alert server would trip on each of them every day.

First, most X activity is replies. We split each account's last 20 X posts into original posts, reposts and replies. Canva had 18 replies, mostly customer support in English, Spanish, Japanese and Portuguese. Framer had 14 replies.

Figma was the exception, with 10 originals, 6 reposts and 4 replies. Without a filter, Claude would draft "response ideas" for dozens of support replies each day. So the server skips posts with is_reply set, through the SKIP_REPLIES switch. It still stores their IDs in seen.json, so they never come back as new.

Second, post dates are not reliable enough to compare. YouTube returns posted_at as relative text such as "23h ago" or "2w ago". One Canva video had a fragment of a title in that field instead of a date. On TikTok, the first three videos for Figma and Canva were pinned, so an old video sits on top of a newest-first list. A rule like "newer than the last poll" fails on all three. An ID rule does not: an ID never changes, so a post you saw once stays seen.

Third, activity is low and uneven. Counting back seven days from 00:32 on November 7, 2026, the three companies posted 19 originals and reposts on X and 10 YouTube videos. Figma alone posted 6 of those videos, mostly Config India talks. Its X feed that week was product news, such as a Figma agent post on turning ideas into vectors on November 5, 2026. On TikTok only Figma posted, twice.

Canva's newest TikTok was from October 30, 2026, and Framer's from May 19. That is 31 non-reply posts in a week from nine sources, or 4.4 a day. Most polls find nothing new, and that is the case a channel handles well.

Test 3: a second round half an hour later, 98.3% already seen

After the first round, we left seen.json as it was. About half an hour later, at 01:08:00 Singapore time, the same watchlist ran again and finished at 01:15:10. Conditions matched the first round: nine sources succeeded for $0.005004, and LinkedIn returned 503 three times and was refunded. This time every source had a baseline, so the dedup did real work.

Source	Rows	Seen before	New posts (pushed)
X · Figma	20	19	1
X · Canva / Framer	20 each	20 each	0
TikTok · Figma / Canva / Framer	10 each	10 each	0
YouTube · Figma	10	9	1
YouTube · Canva / Framer	10 each	10 each	0
Total	120	118	2

Of 120 rows, 118 were already in seen.json, a repeat rate of 98.3%. The LatAm round followed from 01:15 to 01:17. All 50 of its rows from Nubank and Mercado Pago were already seen, so 168 of 170 rows in total. Without dedup, all 120 rows would land in the session. With it, the session got two events, and both were real news.

Figma posted on X at 01:05:20 Singapore time (2026-11-06 17:05:20 UTC) about one-click object isolation and erasing with its AI image tools in the macOS desktop app. The server pushed it at 01:08:12, 2 minutes 52 seconds later. Figma's YouTube channel also posted a video on using Figma's agent for design system docs. The push went out at 01:09:40, and the row said "6 min ago". The other seven sources had nothing new, so the server sent nothing and the model stayed idle.

The LatAm second round ran from 01:15:12 to 01:17:11 Singapore time. All six calls returned 200, with no 503 or 429, for $0.00278. Three rows need a closer look.

Mercado Pago on TikTok returned one profile row only: a verified account with 9,272 followers and 0 videos. The response had data, so it cost $0.000556. Rappi on TikTok also returned one profile row, but the account is private with 0 followers, so it is probably not the brand account. It also cost $0.000556. Rappi on X returned an empty result, and the charge was refunded.

These rows have no post ID, so the server's p?.id filter drops them. Nothing is pushed by mistake, and the server does not crash.

The problem is cost. A profile-only source costs the same per round as a useful one, which is $0.40 a month at hourly polling. So check the first round before you leave the server running. Look at author_video_count and author_follower_count on each row. If an account shows 0, fix the handle or remove it from the watchlist.

The API fee is paid every round, but the model cost depends only on the number of new posts. Do not multiply these two posts into 96 a day. This half hour happened to include a Figma launch, so two posts was a chance peak. The first round gave 31 posts a week, or 4.4 a day on average, so most rounds push nothing. The cost section below counts the two sides separately.

The first event the server pushed, exactly as a Claude Code session would receive it our test client log, 01:08:12 Singapore time, 2026-11-07

The screenshot shows the raw message. content is a few lines of plain text, and Claude Code wraps it in a <channel source="competitor-watch" ...> tag. The four meta keys become tag attributes. They use only letters and underscores, because the docs say keys with hyphens or other characters are dropped without notice. We put charged_usd in meta so Claude can report what each alert cost.

One full round trip: from push to comments

The push is where the work starts. Following the server instructions, Claude adds the post to competitors.md and suggests two responses. Step 4 of the setup below adds the EveryInfra MCP server to Claude Code. With it, Claude can follow the post further by itself. We ran that step directly over MCP with the same key. At 01:15:19 Singapore time we sent tools/call to https://api.everyinfra.com/mcp with the everyinfra_call_api tool, the twitter/comments capability and the post ID.

The MCP drill-down response, with some fields kept and user names and links removed EveryInfra MCP response, 01:15:19 Singapore time, 2026-11-07

The answer came back in 11.3 seconds with 3 rows for $0.000556. Two were replies, posted at 01:08:25 and 01:10:14 Singapore time. One asked whether Figma wants to pack an entire design suite into one app and called it "feature exhaustion". The other joked about erasing exes from holiday photos.

The third row was the post itself: in ten minutes its likes went from 4 to 31 and its views from 1,152 to 2,151. For a product marketer, these rows matter more than the post. Ten minutes after launch, the first reaction already links the feature to bloat, which is an angle worth a response.

Two things we hit are worth knowing in advance. First, twitter/comments returned a rate limit three times between 00:43 and 00:46 Singapore time. Over MCP this is not an HTTP error: it is HTTP 200 with isError: true. The structured content carries retry_after: 60 and a failure count. On the third failure it also suggested a next step: try a sample ID once.

If that fails too, the fault is on the service side. It also said to ask the user before opening a ticket. Claude can act on that without extra prompt text, and none of the three attempts was charged. Second, keep comment pulls on demand, not in the hourly poll. Comments change fastest in the first hour, so one pull when Claude writes its suggestion costs far less than one pull per round.

The cost: API fees, model tokens and official APIs

Start with API fees. Each capability has a price_usd in the catalog, read on November 7, 2026. twitter/user_posts, tiktok/user_videos and youtube/user_posts cost $0.000556 per call. linkedin/company_posts costs $0.002319, 4.2 times more.

Three companies on four platforms make 12 sources, so one round costs at most 9 × 0.000556 + 3 × 0.002319 = $0.011961. Failed, rate-limited and empty calls are free, so this is a ceiling. Our real round cost $0.005004, because LinkedIn returned 503.

Poll interval	Rounds per day	Daily ceiling (USD)	Monthly ceiling, 30 days (USD)	Monthly without LinkedIn (USD)
15 minutes	96	1.148256	34.45	14.41
30 minutes	48	0.574128	17.22	7.21
1 hour	24	0.287064	8.61	3.60
3 hours	8	0.095688	2.87	1.20
1 day	1	0.011961	0.36	0.15

Hourly is a sensible default: $8.61 a month for 12 sources, or $3.60 without LinkedIn. Faster polling raises the bill in step, but these three companies post only 4.4 non-reply items a day. At 15 minutes, almost all of the 96 daily rounds find nothing. At one round a day the bill is $0.36 a month, and then you should ask whether you need a channel at all.

Now the model side. This part is an estimate, not a measurement. Suppose you skip the channel and run /loop every hour, and Claude calls the API and reads the raw rows itself. One round of nine sources was 163,042 bytes. The Anthropic pricing page puts an average 10 kB web page at about 2,500 tokens. So bytes divided by 4 gives about 40,760 tokens per round and 978,252 tokens per day.

At $2 per million input tokens for Claude Sonnet 5.5, that is about $1.96 a day, almost 7 times the API fee. On Opus 5.5 at $4, it is about $3.91 (Anthropic pricing, read November 7, 2026). The channel server dedups and filters first. It pushes about 4.4 posts a day at an average of 235 bytes each, which is about 260 tokens. It wakes Claude about 4 times a day instead of 24.

Two caveats keep this fair. The figures count only data read into the model. They leave out the system prompt, the session context and the output, which depend on your session length and cache hits. And most of the saving comes from deduping outside the model, not from the channel itself. A /loop that runs a dedup script would cut tokens too. What the channel adds is this: no turn at all when nothing is new, and no wait for the next hour when something is.

Finally, compare the official APIs. This table covers one job only: reading a competitor's public posts. Prices and terms come from each vendor's docs, read on November 7, 2026.

Platform	Can the official API read a competitor?	This setup per month (3 accounts, hourly), estimate	Our part, monthly ceiling
X	Yes. Pay per use, $0.005 per post read, charged once per post per UTC day as a "soft guarantee", capped at 3 million reads a month (X API pricing)	About $9.45, at 20 old posts plus about 1 new post per account per day. This assumes the X rule that a post is charged once per UTC day, so 24 polls a day still pay once per post. If that dedup fails and every read is charged, the month costs $226.80	$1.20
YouTube	Yes. 10,000 quota units a day by default; `playlistItems.list` and `videos.list` cost 1 unit each (YouTube quota costs)	About 144 units a day, inside the free quota: $0	$1.20
LinkedIn	Not really. The Community Management API is a vetted product with development and standard tiers. Its stated use is managing company pages for clients (LinkedIn Community Management overview)	Cannot read other companies' pages	$5.01 (503 during our test)
TikTok	Not for commercial monitoring. The Research API is for qualifying non-profit researchers (TikTok Research API); the Display API reads only the authorized user's own videos (Display API)	Cannot read other accounts	$1.20

The YouTube row deserves a plain statement. If YouTube is all you watch, use the official API: it is free and stable for this load. For the other rows, our estimate for the official X API is about $9.45 a month, about 8 times our part. That estimate depends on its best-effort daily dedup. The official LinkedIn and TikTok APIs give no real path to a competitor's account. This table compares access and price only. Code length does not depend on the API you choose: a server on the official APIs can also stay at about a hundred lines.

What changed in eight months

We pulled every channels entry from the Claude Code changelog. They run from 2.1.80 on March 19, 2026 to the latest release we read, 2.1.318 on November 4, 2026. That is 15 entries in total (Claude Code changelog, read November 7, 2026). Launch week alone holds 5 of them. After that, one or two entries land each month. Four of the changes matter most for a competitor-alert channel.

API keys now work. At launch, the docs required a claude.ai login. Version 2.1.128 on May 4 added that --channels "now works with console (API key) authentication". Console organizations with managed settings must set channelsEnabled: true. Many companies give developers API keys rather than claude.ai seats, so this opened channels to them. One blog guide to a headless Discord setup still says API keys do not work. That was true for older versions, and the current docs say otherwise.

Permission relay keeps getting tighter. Version 2.1.81 on March 20 added the relay, so a channel server can forward tool approvals to your phone. Version 2.1.211 on July 15 began to strip bidirectional, zero-width and look-alike quote characters from relayed text. Version 2.1.234 on August 17 limited previews to servers that pass the inbound trust gate. Version 2.1.290 on October 5 fixed a bug where a repeated reply ID could approve a different prompt.

The Channels reference adds that from v2.1.234, recognizable API keys and personal access tokens in relayed text become [REDACTED]. Secrets without a known prefix are not masked (Channels reference, Permission request fields). Our alert server does not declare the relay. It pushes posts; it has no reason to approve tools. The key lives only in the server process environment, and Claude never sees it.

Plugin allowlists got stricter. Version 2.1.84 on March 26 added allowedChannelPlugins for Team and Enterprise admins. Version 2.1.267 on September 9 made an unreadable managed setting admit nothing instead of everything. Version 2.1.281 on September 23 began checking the installed plugin's name, not only its marketplace. If colleagues will use your channel, package it as a plugin in your own marketplace rather than asking everyone to use the development flag.

The MCP runtime moved. The newer Claude Code MCP client negotiates protocol 2026-07-28 with stdio servers. The docs say a server on that version cannot carry channel messages (Claude Code MCP docs). That client is the default from 2.1.274. Meanwhile, @modelcontextprotocol/sdk 1.32.2 shipped on npm on October 23, 2026, with 2025-11-25 as its newest protocol. Today the 1.x SDK is the easy path; with the 2.0 SDK, set MCP_PROTOCOL_NEGOTIATION=legacy. On October 14, 2026, 2.1.299 also fixed --bare sessions that dropped a server named constructor or prototype.

Permissions and safety: what Claude can do with a pushed event

A channel puts outside text into a session that can read and write local files and run commands. So this section is not optional. The docs set gates at three levels. At the plugin level, each approved channel plugin keeps a sender allowlist, and messages from other senders are dropped. Telegram and Discord add your account through a pairing code.

At the session level, an entry in .mcp.json is not enough. You must name the server with --channels at startup. At the organization level, Team and Enterprise plans use the channelsEnabled and allowedChannelPlugins managed settings. Users cannot override them (Channels docs, Security and Enterprise controls).

Our competitor channel accepts no messages from people, so the sender allowlist does not apply to it. The risk is the content, because post text comes from public pages. We already tell Claude that posts are data, and we cut each post to 280 characters. The next step is to give the session no extra permissions.

When Claude reaches a permission prompt while you are away, the session waits for you. The docs give two ways out. A channel can declare permission relay and forward the prompt to your phone. Or you can use --dangerously-skip-permissions, which the docs say to use only in environments you trust (Channels docs, Quickstart; permission modes).

For competitor alerts, we recommend neither. When a new post arrives, Claude only reads, summarizes, and adds rows to competitors.md. Allow writes to that one file in your settings ahead of time. Do not open command execution just to make the setup "fully automatic".

When not to use a channel: a scheduled task is enough

At this point, channels can look like the answer to everything. In fact, they fit a narrow case. We use these questions to decide. If you answer "no" to the first two, skip the channel.

Question	If yes	If no
Must you learn about a competitor move within hours?	A channel, or `/loop` every hour	A daily digest is enough: a Desktop or cloud task
Can one machine keep an interactive Claude Code session open all day?	A channel can work	Use a cloud scheduled task; it needs no machine
Do most polls find nothing new?	The token saving of a channel is largest	When every poll finds something, the model cost is similar
Does your team reach Claude through Bedrock, Google Cloud, or Foundry?	No channels there; use scheduled tasks	Channels are an option
Is your org on claude.ai Team or Enterprise?	An Owner must enable channels first	Individual Pro, Max, and Ultra users opt in per session

Our own conclusion is simple. Most marketing and growth teams read competitor news once a morning. A cloud scheduled task or a GitHub Actions script fits that rhythm better. No machine has to stay on, failed runs leave a record, and the data cost is the same per call. A channel fits a different rhythm.

Think of a competitor launch day or the hours after a competitor outage. It also suits a developer who keeps Claude Code open all day and wants competitor posts there. Also remember that channels are a research preview. The docs say that flags and the protocol can change. Do not build a long-term monitoring system on a preview feature alone.

Limits and things to watch

This section collects the limits that we found in our tests and in the docs. Each row names its source.

Limit	Effect	Source
No events after the session closes	The server exits with the session; posts from the gap arrive on the first poll after restart, late but not lost	Channels docs; our code
Your own channel needs the development flag	A full-screen warning at each start; the flag is ignored with `-p` and the Agent SDK	Channels reference
v2 MCP client and protocol 2026-07-28	A server built on the new SDK may not register; set `MCP_PROTOCOL_NEGOTIATION=legacy`	MCP docs
No delivery receipt	The server cannot tell whether Claude read an event; keep your own state	Channels reference
`meta` keys: letters, digits, underscores	A key with a hyphen is dropped without an error	Channels reference
Research preview	Flags and protocol can change	Channels docs
Not on cloud provider routes	No channels on Bedrock, Google Cloud Agent Platform, or Foundry	Channels docs
Our API can return 503	15 requests between 00:16 and 00:29 SGT got 13 × 503 and 2 × 429, LinkedIn stayed 503 all night, none charged; retry after `retry_after`	Our live calls
LinkedIn company posts cost more	`linkedin/company_posts` is $0.002319 per call, 4.2 times the other three	Catalog `price_usd`

One more limit is not in the table, but many readers ask about it. We can read public posts on public profiles only. Private accounts, follower-only posts, and ad account data are outside these four capabilities. The platforms' own APIs can reach more data, but they also set higher barriers. The cost section above compares them.

Getting started with one source

Build it one step at a time. Each step can be checked on its own, so you do not need all 12 sources on day one.

Step 1: get a key and check prices. Follow the quickstart to create a key, and put it in EVERYINFRA_API_KEY. The pricing page and the catalog list the four prices. The platform pages for X, TikTok, YouTube and LinkedIn show the other capabilities.

Step 2: test one source without Claude Code. Put one source in the watchlist. Run the server once with ONCE=1 under a small MCP client. We used a test client of a few dozen lines that logs every notification to a file. The first run prints a baseline line on stderr and writes seen.json. Run it again later; if the account posted, the client logs one notification. This step checks the key, the parameters and the dedup.

Step 3: attach it to Claude Code. Use the configuration example above and start with --dangerously-load-development-channels server:competitor-watch. Check for the dim line under the banner that says messages go straight into the session. The first event shows in the terminal as a line that starts with ← and names the server, like the webhook example in the docs.

Step 4: add the EveryInfra MCP server. Then Claude can pull comments on a new post by itself. The command follows the remote HTTP form in the Claude Code docs. The MCP server page lists the tools, and the remote MCP setup guide walks through it.

claude mcp add --transport http everyinfra https://api.everyinfra.com/mcp \
  --header "Authorization: Bearer $EVERYINFRA_API_KEY"

Step 5: review after a week. Call watch_status for polls, pushes and spend. Remove sources with no new posts in a week, or move them to a daily task. The marketplace lists ready-made tools, and the refund reconciliation guide shows how failed calls are refunded.

FAQ

Why do I see "Claude Code channels are not currently available"?

There are four usual causes. Your version is too old: channels arrived in v2.1.80, and v2.1.83 fixed a false "Channels are not currently available" message on the first launch after an upgrade. Your sign-in does not qualify: channels need a claude.ai account or a Console API key. They do not exist on Bedrock, Google Cloud Agent Platform, or Foundry.

Your org blocks them: claude.ai Team and Enterprise keep channels off until an Owner turns them on. Or the plugin that you passed to --channels is not on the allowlist, and the startup notice says why. (Question source: Google suggestion "claude code channels are not currently available"; answer based on the Channels docs and changelog v2.1.83.)

What is the difference between Claude Code channels and Remote Control?

They point in opposite directions. With Remote Control, you drive a running local session from your phone or the web. With a channel, an outside system pushes an event into the session, and Claude reacts on its own. Remote Control can also send mobile push notifications when a task ends or needs a decision. But Claude decides when to push, and you cannot set rules per event. (Question source: Google suggestion "claude code channels vs remote control"; answer based on the Remote Control docs.)

Can Claude Code channels connect to Slack or WhatsApp?

In the research preview, the official channel plugins are Telegram, Discord, iMessage, and the fakechat demo. Slack has a separate product, Claude in Slack, which starts a new cloud session. It is not a channel. WhatsApp has no official plugin. If you build one, you must use the development flag and check senders the way the official plugins do. (Question source: Google suggestions "claude code channels slack" and "claude code channels whatsapp"; answer based on the Channels docs and the Claude in Slack docs.)

How do I test claude code custom channels?

Use claude --dangerously-load-development-channels server:<name> for a server in .mcp.json, or plugin:<name>@<marketplace> for a plugin. The flag skips only the allowlist. The channelsEnabled org policy still applies, and the flag is ignored with -p or the Agent SDK. An empty allowedChannelPlugins array does not stop the development flag. To block channels fully, an admin must leave channelsEnabled unset. (Question source: Google suggestion "claude code custom channels"; answer based on the Channels reference.)

My Claude Code push notifications do not work. Is that a channel problem?

Probably not. Mobile push is a Remote Control feature. You need the Claude mobile app, the same account, and one of the "Push when Claude decides" or "Push when actions required" settings in /config. Claude Code also skips pushes while you type in the connected terminal.

A channel pushes messages into the session, not to your phone. To get competitor alerts on your phone, let Claude forward a summary through the reply tool of the Telegram plugin. (Question source: Google suggestions "claude code push notifications not working" and "claude code remote control push notifications"; answer based on the Remote Control docs and the Telegram plugin README.)

The Telegram plugin shows "1 MCP server failed". What now?

Check that Bun is installed. In an r/ClaudeCode thread, a user followed the docs step by step and got "1 MCP server failed" after about 30 seconds. A reply said that Bun was missing, and installing it fixed the problem. Another user still got no pairing code until a new terminal picked up the bun command. The docs mention Bun at the top of the "Supported channels" section, which is easy to skip. (Question source: r/ClaudeCode thread; answer based on the Channels docs.)

Snowflake Cortex Agents MCP: how to load social complaints next to your returns

EveryInfra — Sat, 07 Nov 2026 05:58:13 +0000

Returns are one of the largest hidden costs in consumer retail. The National Retail Federation estimated that US shoppers would return about $849.9 billion of merchandise in 2025. That is 15.8% of sales, and the rate for online purchases is 19.3% (NRF press release). Most brands already load sales and return data into a warehouse. Far fewer brands load what customers say in public about the product. This article connects the two inside Snowflake.

The trigger is Snowflake Expedition 2026. On November 3, 2026, Snowflake launched CoWork, the new name for Snowflake Intelligence, and new Cortex Agents features (press release). The feature that caught our attention is MCP connectors. With them, an agent can call tools on an outside MCP server (MCP connectors documentation). A brand team will see the use case at once. Put Amazon reviews, Reddit posts and TikTok comments next to the sales and returns tables. Then ask the agent which complaint theme rises together with the return rate.

We tested the data side for real. Between 00:16 and 00:36 Singapore time (SGT) on 2026-11-06, we made 12 calls to the EveryInfra API. We kept every request and response. The Snowflake side in this article is configuration examples only. We do not have a Snowflake account on this machine, so we did not run the SQL, the procedures or the agent. Every Snowflake fact comes from snowflake.com or docs.snowflake.com, with the read date in References.

Here is the short answer. You cannot add the EveryInfra MCP server as a Snowflake MCP connector today.

Snowflake accepts only OAuth, and it needs a specific client registration that our server does not offer yet. Even with OAuth, a connector would not solve this problem, because connector results stay inside one chat and never reach a table. The route that works is a Snowflake external access integration. A Python stored procedure calls the API on a schedule and writes the reviews into tables. Then a Cortex Agent joins those tables with sales and returns. Be clear about what this article does not show. The Amazon review calls returned no data that night, and we have no returns data, so you get a build plan and a cost estimate, not a finding about which complaint drives returns. EveryInfra has no partnership with Snowflake. Every Snowflake fact here comes from its public documents and press releases.

Key takeaways

Snowflake MCP connectors accept OAuth only. The remote server must support dynamic client registration, or you must register a client with the callback https://identity.snowflake.com/oauth2/callback. EveryInfra meets neither condition today.

The working route has five parts. They are a network rule, a key secret, an external access integration, a Python procedure and a task. The agent then reads tables, not live tools.

Our 12 live calls cost $0.005016 in total. All 5 Amazon review calls returned no data (4 returned 503, temporarily unavailable, and 1 returned an empty result), and none of them were charged.

In 273 TikTok comments on two videos, 17 described a product problem. The largest group was lid and spill problems (6). In the 200 comments on the comparison video, a keyword rule matched 42, and only 4 of those were real product problems (9.5%).

For one brand, the API fee is about $1.26 a month. The largest Snowflake cost is a warehouse that waits for HTTP responses: about $40.54 a month serially, about $4.05 with 10 parallel calls.

The MCP connector door needs a registered OAuth client, and an API key does not fit. The external access side gate allows one fixed host and moves the data straight into tables.

What Snowflake launched at Expedition 2026: snowflake cowork and Cortex Agents

The main product of the event is Snowflake CoWork. The press release describes it as an agent workspace for business users at ai.snowflake.com. Cortex Code, or CoCo, is the companion tool for developers and data engineers (Expedition 2026 press release, CoWork product page).

A second press release on the same day announced Business Ontology and Cortex AI Gateway. Business Ontology stores the approved meaning of business terms and serves those definitions to agents. Cortex AI Gateway governs how agents access models, invoke tools and take action across company systems (Business Ontology and AI Gateway press release). Both matter for our question later. A term such as "return rate" needs one agreed formula, or two agents will give two different answers.

For this article, CoWork is the place where people ask, and Cortex Agents do the work.

Each CoWork assistant is a Cortex Agent object. The agent specification lists its model, its instructions and its tools. The tools include Cortex Analyst for SQL over semantic views and Cortex Search for text. Other tools are code execution, custom tools, MCP connectors and web search (Cortex Agents overview, Create and manage agents). So the quality of the answer depends mostly on the tables and the semantic view. The agent turns a question into SQL and explains the result.

The table below shows the status of the two features that matter here, as we read it on 2026-11-06. "Not stated" means that neither the documentation nor the press release names a status.

Feature	Status on 2026-11-06	Source
CoWork Automations	Not stated	Automations docs
Cortex Agents MCP connectors	Docs do not state a status, OAuth only	Connectors docs

The CoWork blog post also mentions analytical search, which is in preview. Its example is close to ours: which customer issues came up most last month (CoWork blog). The Automations limits and access rules are in the weekly email section below.

Analytical search works on documents that are already in Snowflake. It narrows the set with Cortex Search, then counts and compares with AI functions and SQL. Our problem has one extra step. The customer voice lives on Amazon, Reddit and TikTok, outside the warehouse. So the first job is to move it in, on a schedule, in a shape that joins with sales and returns.

Can snowflake cortex agents mcp connect to EveryInfra directly?

This is the obvious first idea. EveryInfra already runs a remote MCP server (EveryInfra MCP server). Cortex Agents can now call outside MCP servers. So why not paste the server address into Snowflake? We compared the Snowflake requirements with what our server does, one item at a time. The answer is no, and the blocker is how the OAuth client is registered.

The Snowflake documentation is direct about it. It says that Snowflake supports only OAuth for MCP server connections. An admin creates an API integration with API_PROVIDER = external_mcp that holds the OAuth settings. Then the admin creates an external MCP server object that points to that integration (MCP connectors documentation). There are two ways to fill in the OAuth settings.

The first way is standard OAuth. You register an app with the remote authorization server and get a client ID. The client can have a secret, or it can be a public client without one.

You must also register the callback URL https://identity.snowflake.com/oauth2/callback with that app. The second way is dynamic client registration, where Snowflake asks the remote server for a client ID by itself. That needs the remote server to implement RFC 7591 (RFC 7591). The ready-made connectors are Atlassian, GitHub, Glean, Linear and Salesforce, and the Atlassian example uses dynamic registration.

EveryInfra has two MCP addresses. The common one, https://api.everyinfra.com/mcp, uses an API key in a Bearer header. At 00:43 SGT on 2026-11-06, we requested its protected resource metadata and its authorization server metadata. Both returned 404, so this address does not offer OAuth discovery. The full address, https://api.everyinfra.com/mcp/all, behaves differently. In the same minute, a request without credentials returned 401 with a WWW-Authenticate header.

That header points to resource metadata in the RFC 9728 format, and the metadata names auth.everyinfra.com/oidc as the authorization server (RFC 9728). We then read the authorization server metadata, which follows RFC 8414 (RFC 8414). It supports PKCE with S256 and public clients without a secret. But its registration_endpoint value is empty, so there is no dynamic registration. Our public documentation also has no self-service page where a customer can register an OAuth client.

What Snowflake needs	EveryInfra `/mcp` (API key)	EveryInfra `/mcp/all` (tested 00:43 SGT, 2026-11-06)
OAuth only	No, it uses a Bearer API key	Yes, 401 with RFC 9728 metadata
Dynamic client registration (RFC 7591)	Not applicable	No, the metadata has no registration endpoint
Standard OAuth with a registered client and callback	Not applicable	No self-service registration in public docs
Tool capabilities only	Yes, all tools are MCP tools	Yes
Host name without underscores	Yes	Yes

The MCP specification itself does not require OAuth. Version 2025-06-18 says that authorization is optional. If a server supports it, the server must publish RFC 9728 and RFC 8414 metadata, and dynamic registration is a "should", not a "must" (MCP authorization, 2025-06-18). So an API key server follows the specification, and an OAuth-only client also follows it. The two simply do not meet.

Snowflake has a second place for outside MCP servers. Cortex AI Gateway lets an admin add a custom MCP server. Its documentation also requires OAuth, a URL that ends in /mcp, and the ACCOUNTADMIN role (AI Gateway custom apps). Our OAuth address ends in /mcp/all, and our address that ends in /mcp takes only a key. No single address meets both conditions.

Suppose the registration problem goes away. A connector still would not fit this job. Each user clicks Connect in CoWork, signs in on the remote page and approves access. After that, the agent calls the remote tools during a chat, and the results stay in that chat (Use MCP connectors in Snowflake CoWork). Every person who asks needs their own EveryInfra account. More importantly, no review ever lands in a table, so the agent cannot join three months of reviews with three months of returns.

A question about trends needs history, and history lives in tables. Connectors suit a different kind of question, for example "what are people arguing about under this video right now". That question is one-off and needs no storage.

We found four ways to connect Snowflake with an outside data API. The table sorts them by two tests: does the data reach a table, and does the route need OAuth.

Route	Data lands in a table	Needs OAuth	Good for	Source
MCP connector (external MCP server object)	No, chat only	Yes	One-off questions	Connectors docs
External access integration, stored procedure and task	Yes	No, the key sits in a secret	Daily loads, our pick	External network access
Collector outside Snowflake, then Snowpipe	Yes	No	Teams that already run collectors	Snowpipe
External MCP in the Cortex Code Agent SDK	No, unless your code writes back	No, headers are allowed	Developers testing in code	Agent SDK custom tools

In the fourth route, a Snowflake developer tool lets you put an API key in a request header (Agent SDK documentation). That route lives in developer code, not in the CoWork business interface. The rest of this article follows the second route, because it writes data into tables on a schedule under normal Snowflake access control.

The working route: external access and a stored procedure (configuration example)

The whole flow fits in one picture. The EveryInfra API collects public reviews and comments from Amazon, Reddit and TikTok. Inside Snowflake, a scheduled task calls a stored procedure once a day. The procedure calls the API through an external access integration, stores each raw response, and then expands it into review tables. Your own sales data and Amazon FBA returns report load into two more tables, as they do today. A semantic view and a Cortex Agent sit on top, and business users ask questions in CoWork.

An external access integration is the standard Snowflake way to let procedures and functions reach the internet. It uses three objects. A network rule lists the hosts and ports that code may reach. A secret holds the credential. The integration ties the two together. You grant it to specific roles (External network access overview, Creating and using an external access integration).

Our rule allows only api.everyinfra.com. Even if someone edits the procedure code, it cannot reach another host. The key stays in the secret object, so the code never contains it in plain text. The role that runs the procedure cannot read it either. In the example below, voc is the database name. It stands for "voice of the customer".

-- 1. Allow outbound traffic to one host only
CREATE OR REPLACE NETWORK RULE voc.raw.everyinfra_egress
  MODE = EGRESS
  TYPE = HOST_PORT
  VALUE_LIST = ('api.everyinfra.com');

-- 2. Store the API key. Create a separate key in the EveryInfra console
--    and give it its own per-minute call limit.
CREATE OR REPLACE SECRET voc.raw.everyinfra_key
  TYPE = GENERIC_STRING
  SECRET_STRING = '<EveryInfra API key>';

-- 3. Tie the rule and the secret together
CREATE OR REPLACE EXTERNAL ACCESS INTEGRATION everyinfra_access
  ALLOWED_NETWORK_RULES = (voc.raw.everyinfra_egress)
  ALLOWED_AUTHENTICATION_SECRETS = (voc.raw.everyinfra_key)
  ENABLED = TRUE;

-- 4. Grant it only to the loading role
GRANT USAGE ON INTEGRATION everyinfra_access TO ROLE voc_loader;
GRANT READ ON SECRET voc.raw.everyinfra_key TO ROLE voc_loader;

The syntax follows the Snowflake SQL reference (CREATE NETWORK RULE, CREATE SECRET, CREATE EXTERNAL ACCESS INTEGRATION). Creating the integration needs an account-level privilege, so an admin usually does it once. After that, the loading role only needs usage on the integration and read on the secret. The Snowflake examples page shows complete procedures that call outside APIs with a secret (External network access examples).

The procedure has one design choice that changes the bill: wait for each result, or submit and come back later. The EveryInfra API supports both.

A synchronous call holds the connection open until the data arrives. In our test, the slowest Amazon review call held it for 67 seconds. An asynchronous call adds "mode": "async" to the request body. The API answers with status 202 and a job ID in about two seconds. You fetch the result later with GET /api/v1/jobs/{job_id} (Docs).

In Snowflake, that difference turns into money. The procedure runs on a warehouse, and the warehouse bills for every second it runs. Each second of waiting is a billed second. So we split the load into two procedures and two tasks. One procedure only submits, and it finishes in seconds. The other collects the jobs that are done.

The table lists every Snowflake object in this setup, what it does and who usually creates it.

Object	Purpose	Usually created by
Network rule `everyinfra_egress`	Allows outbound traffic to one host	Account admin
Secret `everyinfra_key`	Holds the EveryInfra API key	Account admin
External access integration `everyinfra_access`	Ties the rule and the secret together	Account admin
Procedure `submit_pulls`	Submits async jobs for each watchlist row	Data engineer
Procedure `collect_results`	Collects finished jobs into raw tables	Data engineer
Tasks `t_submit` and `t_collect`	Run the two procedures on a schedule	Data engineer
Semantic view `voc_returns`	Defines themes, weeks and return measures	Analytics engineer

        ).collect()
        submitted += 1
    return {"submitted": submitted}
$$;

The procedure follows the Snowflake guide for Python procedures. The SECRETS clause maps the secret object to a name, and the code reads it with _snowflake.get_generic_secret_string. The PACKAGES clause lists the outside packages (Python stored procedures overview). Two details are worth copying. First, keep the full first response. It states the exact dollar charge, so you can reconcile with the EveryInfra billing page each month.

Second, do not retry the same target inside the procedure. The API does not charge for bad parameters, temporarily unavailable targets or empty results, and the response says why. Let tomorrow's run try again. Our Amazon 503 responses even said that an immediate retry on the same item was unlikely to help.

The collector has the same shape. It reads job IDs that are still open in voc.raw.jobs and asks for each status. It skips jobs that are running or finalizing. It writes finished results into voc.raw.api_responses and marks them as collected. In our own test, we first treated only running as unfinished. As a result, we read one job too early, while it was still finalizing. Add both states to the check.

Schedule the submit task for 02:00 Singapore time each day. Schedule the collector for 02:20 and 03:20, so the second run picks up anything the first run missed. Do not run the collector every few minutes. Each warehouse resume bills at least 60 seconds, so frequent runs mostly buy idle time. We also suggest an auto-suspend of 60 seconds instead of the default of 10 minutes.

CREATE OR REPLACE TASK voc.raw.t_submit
  WAREHOUSE = voc_xs_wh
  SCHEDULE = 'USING CRON 0 2 * * * Asia/Singapore'

  CALL voc.raw.collect_results();

ALTER TASK voc.raw.t_collect RESUME;
ALTER TASK voc.raw.t_submit RESUME;

Task syntax is in CREATE TASK and the introduction to tasks. You can also remove WAREHOUSE and use a serverless task, which Snowflake bills by actual compute. The Service Consumption Table lists a 0.9 multiplier for serverless tasks (Service Consumption Table).

Four tables: reviews, social mentions, sales and returns

Three rules shape the tables. Keep each raw response as it arrived. Keep only the fields that the analysis needs in the expanded tables. Drop personal data when you can. The API returns reviewer names and avatars, and the return-rate analysis never uses them. Dropping them saves storage and removes a privacy question. Below are four core tables and one mapping table. Sales and returns come from your own systems, so we show only their structure.

-- Raw responses: one row per API response, stored as VARIANT
CREATE TABLE IF NOT EXISTS voc.raw.api_responses (
  job_id        STRING,
  platform      STRING,
  action        STRING,
  fetched_at    TIMESTAMP_TZ,
  payload       VARIANT
);

-- Amazon reviews (expanded from amazon/reviews)
CREATE TABLE IF NOT EXISTS voc.core.reviews (
  review_id            STRING PRIMARY KEY,
  asin                 STRING,
  country              STRING,
  rating               NUMBER(3,1),
  title                STRING,
  body                 STRING,
  posted_at            TIMESTAMP_TZ,
  is_verified_purchase BOOLEAN,
  helpful_count        NUMBER,
  variant              STRING,
  fetched_at           TIMESTAMP_TZ
);

-- Social mentions: TikTok comments and Reddit posts in one table
CREATE TABLE IF NOT EXISTS voc.core.social_mentions (
  platform      STRING,          -- tiktok or reddit
  source_id     STRING,          -- comment or post ID
  source_url    STRING,          -- video URL or post URL
  community     STRING,          -- Reddit community, empty for TikTok
  product_key   STRING,          -- key from product_map
  body          STRING,
  like_count    NUMBER,
  reply_count   NUMBER,
  is_reply      BOOLEAN,
  posted_at     TIMESTAMP_TZ,
  fetched_at    TIMESTAMP_TZ,
  themes        ARRAY,           -- labels from AI_CLASSIFY
  PRIMARY KEY (platform, source_id)
);

-- Daily sales from your order system
CREATE TABLE IF NOT EXISTS voc.core.sales_daily (
  sale_date     DATE,
  sku           STRING,
  asin          STRING,
  units_ordered NUMBER,
  PRIMARY KEY (sale_date, sku)
);

-- FBA customer returns report (GET_FBA_FULFILLMENT_CUSTOMER_RETURNS_DATA)
CREATE TABLE IF NOT EXISTS voc.core.fba_returns (
  return_date           TIMESTAMP_TZ,
  order_id              STRING,
  sku                   STRING,
  asin                  STRING,
  fnsku                 STRING,
  quantity              NUMBER,
  fulfillment_center_id STRING,
  detailed_disposition  STRING,
  reason                STRING,
  status                STRING,
  customer_comments     STRING,
  return_themes         ARRAY
);

-- Product map: which ASINs, SKUs, videos and keywords belong to one product
CREATE TABLE IF NOT EXISTS voc.core.product_map (
  product_key   STRING,
  asin          STRING,
  sku           STRING,
  tiktok_urls   ARRAY,
  reddit_terms  ARRAY
);

The returns table copies the Amazon SP-API FBA customer returns report. The report type is GET_FBA_FULFILLMENT_CUSTOMER_RETURNS_DATA. Its fields include return date, order ID, SKU, ASIN, FNSKU, product name, quantity, fulfillment center, detailed disposition, reason, status, license plate number and customer comments. The documentation says that Amazon updates it daily (SP-API FBA report types).

The customer comments column matters most here. It is free text, like a TikTok comment. If you classify both with the same theme list, the two sides line up by theme. The reason column uses fixed Amazon codes, which are much coarser than a theme such as "the lid leaks". Reason codes alone cannot tell you which theme drives returns.

The next table maps API fields to table columns. Field names come from the EveryInfra catalog at GET /api/v1/social/catalog, read on 2026-11-06 (catalog).

Capability	API fields	Table column	Note
`amazon/reviews`	`review_id`, `product_asin`, `country`	`reviews.review_id`, `asin`, `country`	Deduplicate on review ID
`amazon/reviews`	`rating`, `title`, `text`, `posted_at`	`rating`, `title`, `body`, `posted_at`	Rating from 1 to 5
`amazon/reviews`	`is_verified_purchase`, `helpful_count`, `variant`	Same names	Color and size live in `variant`
`amazon/reviews`	`author_name`, `author_id`, `author_avatar_url`	Not stored	Personal data the analysis does not need
`tiktok/comments`	`id`, `text`, `like_count`, `reply_count`, `is_reply`, `posted_at`	Matching `social_mentions` columns	Each top comment carries up to 2 replies
`tiktok/comments`	`author_username`, `author_id`	Not stored	Same reason
`reddit/search`	`id`, `url`, `title` plus `text`, `community`, `like_count`, `comment_count`	`source_id`, `source_url`, `body`, `community`, `like_count`, `reply_count`	Title and body joined into one text
`reddit/search`	`author_username`	Not stored	Same reason

The expand step needs only SQL. Select rows by platform from api_responses, use LATERAL FLATTEN on payload:results, and MERGE into the target table on the ID. When you pull the same video again, old comments get new like counts and new comments are appended. Later in this article, you will see that pulling the same video again after some months is the most useful step in this setup.

One real round trip: REST, async and MCP

We could not run the Snowflake side. But the procedure sends the same requests to the same API that we used on our own machine. It gets the same response format. Between 00:16 and 00:36 SGT on 2026-11-06, we made 12 calls with a test key. They cover the three capabilities in this article, plus two searches that helped us choose targets. We kept the request, start and end time, HTTP status, duration and charge for each call.

#	SGT	Capability	Mode	Result	Duration	Charge
1	00:16:52	`amazon/search`, keyword portable blender	Sync	10 products, 9 of them Ninja	42.14 s	$0.002236

3	00:18:41	`amazon/reviews`, product B0CN3S2SW2	Sync	503	58.57 s	$0

7	00:21:21	`tiktok/comments`, cheap-versus-expensive test video	Sync	200 comments	52.30 s	$0.000556
8	00:22:13	`walmart/reviews`, product page	Sync	0 rows, empty result refunded	54.34 s	$0
9	00:24:22	`amazon/reviews`, product B0D2YYHN1B	Sync	503	19.48 s	$0
10	00:25:26	`reddit/search`, ninja blast	MCP	7 posts	7.62 s	$0.000556
11	00:27:36	`tiktok/comments`, single-product try-on video	Async	202, done after about 100 s, 73 comments	Submit 1.95 s	$0.000556
12	00:36:23	`amazon/reviews`, product B0C2FF4JD1 again	Sync	503	38.42 s	$0

Six of the 12 calls were charged, for a total of $0.005016. The other six returned 503 or an empty result, and none were charged. We guessed the Walmart product URL in call 8 from a product name, so the empty result is our own mistake. It still confirms that the empty-result refund also applies to Walmart reviews.

Screenshot of the async submit and result at 00:27 SGT on 2026-11-06, and a 503 response at 00:17. Author data is hidden. EveryInfra API response

Part one of the screenshot is what the submit procedure receives. It returned 202 in 1.95 seconds with a job ID, and the response states the charge of $0.000556 at submit time. Part two is what the collector receives. The state moved from running to finalizing to succeeded. We polled about every 8 seconds, 12 times in total, and the job finished about 100 seconds after submit.

Part three shows a failure. The status is 503, the reason is access_blocked, the suggested retry is after 900 seconds, and the charge is 0. A procedure only has to branch on the status code and these fields.

Call 10 is for comparison. It ran the same Reddit search through the MCP tool everyinfra_call_api. It returned 7 posts in 7.62 seconds as a tool result of 18,619 characters, inside a 19,490-byte response. If a Cortex Agent made that call through an MCP connector, those 18,619 characters would go into the model context as input tokens. The same data loaded into a table costs the agent only the few rows it reads. This is why we prefer "load first, ask later" to "fetch live in every chat".

This latency chart decides the Snowflake cost model. By data size, all three capabilities are light. One TikTok comments call with 200 comments was 71,228 bytes, and one Reddit search was about 30,000 bytes. By waiting time, a synchronous review or comment call often takes 50 to 70 seconds.

A warehouse bills per second, with a 60-second minimum each time it resumes (Warehouses overview, Understanding compute cost). During a synchronous call, the warehouse spends nearly all its time waiting on the network. The cost section turns that into dollars.

Test 1: how many TikTok comments describe a product problem?

We picked a category that most readers know: portable blenders. Call 1 used amazon/search for "portable blender". Nine of the top 10 results were Ninja products, priced from $19.95 to $59.99 (Amazon data API, Amazon search). Call 6 used tiktok/search for "ninja blast portable blender review". From the 10 videos it returned, we took the two with the most comments. We pulled their comments with tiktok/comments (TikTok data API, TikTok comments API, TikTok search API).

The first video is a "cheap versus expensive" blender test posted on 2025-07-27. When we pulled it, it had 2,586,703 views and 251 comments. We received 200 comments, which is the limit for one call. The second video is a single-product try-on posted on 2026-01-20, with 208,916 views and 98 comments. We received 73, of which 17 were replies. This article does not name either creator.

Video	Posted	Views	Comments on video	Comments received	Replies	Product problems	Share
Cheap-versus-expensive test	2025-07-27	2,586,703	251	200	23	4	2.0%
Single-product try-on	2026-01-20	208,916	98	73	17	13	17.8%

First we tried the most common shortcut: a keyword list. Battery, leak, broke, returned, expensive, too small. A comment that matched any word counted as a complaint. In the first video, the list matched 42 of 200 comments. Then we read every comment by hand. Only 4 of the 42 described a problem with the blender, so the keyword rule was right 9.5% of the time.

The reason is easy to see. The comment section of a "cheap versus expensive" video is mostly jokes about the format, with requests to test cheap and expensive versions of other things. Thirty comments matched "expensive" or a price word. Only 7 of them said the blender was not worth the price. In Snowflake, theme labels must come from a model, and you must define "product problem" in writing first.

The table shows our hand labels for the 42 comments that the keyword list matched in the first video.

Hand label	Comments
Not a product signal (jokes, other topics)	29
Price objection only	7
Product problem	4
Unclear	2
Total keyword matches	42

Our hand-labeling rule was strict. A comment counts only if it says this product had a problem. The problem types are lid or spill, short battery life, weak on ice, a missing part, hard to clean and broke quickly. A general "not worth it, I returned it" also counts. Price complaints, brand comparisons, jokes and emoji do not count. With that rule, the two videos look very different.

The video with ten times more views has only 2.0% product-problem comments. The smaller try-on video has 17.8%. The reason is the audience. A comparison video attracts people who watch for fun. A try-on video attracts people who own the product or plan to buy it, and they are the ones who write "mine leaked too". For the Snowflake design, the choice of videos in product_map matters more than the number of comments per video.

At the same price of $0.000556 per call, a try-on video gave almost nine times more signal. You can automate that choice too. Search with tiktok/search, then keep videos whose captions use words such as "review", "trying" or "honest" and that have tens to hundreds of comments.

Across both videos, 17 of 273 comments described a product problem. The themes break down as follows.

Theme	Comments	Example (original text, author hidden)	Likes
Lid or spill	6	The way I just gasped when it spilled. Were you supposed to open it from the top instead?	79
Battery	3	the batteries do not last long enough to make a full smoothie	9
General negative, returned	2	Not worth it, returned after a week	0
Weak on ice or frozen fruit	2	It's not. I returned mine. Barely could get through frozen fruit	97
Missing part	2	ours both didn't come with the blade cap	0
Broke quickly	1	they are shit, lasts 2 spins	1
Hard to clean	1	Hard to wash	0

Lid and spill problems form the largest group. The most liked comment in that group, with 79 likes, asks whether you should open the lid from the top instead. Another says the writer spilled it the same way the first time and did not think to use the cap. A comment from 2026-01-22 warns others not to use the button on the lid, because it breaks and no replacement is sold.

This kind of problem differs from battery or motor complaints. Better instructions, packaging or product photos can often fix it, and the return rate can then fall quickly. That is exactly what the question "which complaint theme rises with returns" is meant to find. Once a theme lines up with a return spike, the action is concrete.

Keep the like count in the table. A "I returned mine" comment with 97 likes and a complaint with 0 likes do not speak for the same number of people. In the semantic view, define two measures: the comment count, and a like-weighted count. Ask the agent to report both.

In Snowflake, AI_CLASSIFY can do the labeling. Use the seven themes plus "not a product issue" as categories. Set multi-label output. Add a task description that excludes price complaints and jokes. The documentation recommends no more than about 20 categories, and it accepts examples (AI_CLASSIFY documentation).

One usage note in that documentation matters. Input in English gives the best results, and other languages can perform worse. Most TikTok and Amazon US comments are in English, so this is a small issue for a US brand. If you also track Spanish-language or other markets, check a hand-labeled sample first. The task description and the categories also count as tokens on every row. So the real token count per row is higher than the comment length.

UPDATE voc.core.social_mentions
SET themes = AI_CLASSIFY(
      body,
      ['lid_or_spill', 'battery', 'weak_on_ice', 'missing_part',
       'breaks_quickly', 'hard_to_clean', 'general_negative', 'not_a_product_issue'],
      {'output_mode': 'multi',
       'task_description': 'Label only comments that report a problem with this blender. Price complaints, jokes and brand comparisons are not_a_product_issue.'}
    ):labels
WHERE themes IS NULL;

Run the same classification on the customer_comments column of the returns table and write the result into return_themes. Both sides then use the same themes, the same model and the same description, so a comparison by theme makes sense. AI_SENTIMENT can also score each comment from negative to positive (AI_SENTIMENT documentation). It helps less here, because the question is which problem, not how unhappy.

Test 2: what does a Reddit search return?

Many teams treat Reddit as the home of honest user talk, so we checked whether it could add to TikTok. Call 5 used reddit/search for "portable blender", sorted by newest, and returned 14 posts. Call 10 searched "ninja blast" through MCP and returned 7 posts (Reddit data API, Reddit search API). This capability always searches the last month and returns up to 25 posts per call. Our 14 posts covered only 2026-10-30 to 2026-11-05 (UTC), and the 7 posts covered November 3 to November 5.

We read every post. None of the 21 discussed whether a blender works well. Of the 14 "portable blender" posts, 10 were deal posts. Most were in deal communities such as r/priceglitch, with titles like "Ninja Blast Max Portable Blender, Twist & Go, 22oz" plus a color and a price. Deal posts appeared on 2026-10-31, 2026-11-01 and 2026-11-05. Daily Amazon deal roundups appeared on 2026-11-02 and 2026-11-03.

The other 4 posts had nothing to do with blenders. One user asked about a portable ThinkPad, and two posts in 3D software Blender communities asked about laptop specs. Of the 7 "ninja blast" posts, 4 were deals. The other 3 matched the word by accident: one was about a video game, and two were in a community for the Ninjago animated series.

Query	Posts	Deal posts	Off topic	Product talk	Date range (UTC)
portable blender (REST)	14	10	4	0	2026-10-30 to 2026-11-05
ninja blast (MCP)	7	4	3	0	2026-11-03 to 2026-11-05

This does not mean Reddit is useless. It means a short keyword sorted by newest is the wrong query. For a Snowflake load, make three changes. First, judge relevance on the title only, and require "blender" to follow portable, personal, smoothie or a brand name. Our first rule matched "blender" in post bodies and counted 3D software posts as product posts.

Second, keep deal posts as their own category, because they are useful data. How often one blender appears in deal communities in a month, and at what price, can sit next to your sales table. You can then see whether a deal week leads to a return spike. Third, real product talk tends to live in a few communities, such as smoothie or fitness food groups. Use reddit/comments on relevant threads there, instead of a site-wide search.

Test 3: Amazon reviews returned 503, and nothing was charged

The data we wanted most was Amazon reviews. Reviews and returns come from the same platform and the same buyers. But our five amazon/reviews calls returned no reviews at all (Amazon reviews API). At 00:17, 00:18 and 00:24 SGT, three different Ninja and Hamilton Beach products each returned 503 with the reason access_blocked. That means reviews for the item were temporarily unavailable, nothing was charged, and the response suggests a retry after 900 seconds.

At 00:19 SGT we tried an older product. It returned 200 with 0 rows, and the call was refunded as an empty result. At 00:36 SGT, 19 minutes after the first try, we called the first product again and got 503 again. All five calls show charged_usd as 0.

SGT	Product	HTTP status	Reason	Duration	Charge
00:17:41	B0C2FF4JD1	503	`access_blocked`	60.12 s	$0
00:18:41	B0CN3S2SW2	503	`access_blocked`	58.57 s	$0
00:19:47	B09B8V1LZ3	200	Empty result, refunded	67.25 s	$0
00:24:22	B0D2YYHN1B	503	`access_blocked`	19.48 s	$0
00:36:23	B0C2FF4JD1	503	`access_blocked`	38.42 s	$0

We report this as it happened, because a daily Snowflake task will meet the same thing. Under EveryInfra rules, targets that are temporarily unavailable or need a login return 503 with a reason and a retry hint. They never return an empty 200 that claims there are no reviews. This difference matters for the loader. A 503 means "no data today, try tomorrow". An empty 200 means "there really is nothing here".

If the procedure mixes the two, the semantic view will show fake "zero complaint" days for some products. The agent will then draw wrong conclusions from them. Store the HTTP status and reason in the jobs table. Expand only responses with status 200. Add a "days with missing data" measure to the semantic view, so the agent can say which days had no data.

The catalog also says that amazon/reviews returns only the featured reviews shown on the product page. That is usually a dozen or so per product, with a maximum of 100 per call, across 11 Amazon marketplaces.

So even on a good day, it is not every review. It is the set that Amazon chooses to show. That set is fine for "what do the most visible complaints say". It is not enough to count all complaints. For full counts, your Seller Central data and the customer comments in the FBA returns report are more complete. That report feeds the fba_returns table above.

Ask the Cortex Agent: which complaint theme rises with the return rate?

Once the tables exist, build a weekly view. Each row holds one product, one theme and one week, with the social mention count, the returned units and the units sold. The theme return rate is returned units for that theme divided by units sold in that week.

CREATE OR REPLACE VIEW voc.core.theme_returns_weekly AS
WITH mentions AS (
  SELECT s.product_key,
         DATE_TRUNC('week', s.posted_at)::DATE AS week_start,
         t.value::STRING AS theme,
         COUNT(*) AS mentions,
         SUM(1 + COALESCE(s.like_count, 0)) AS weighted_mentions
  FROM voc.core.social_mentions s,
       LATERAL FLATTEN(input => s.themes) t
  WHERE t.value::STRING <> 'not_a_product_issue'
  GROUP BY 1, 2, 3
),
returns AS (
  SELECT pm.product_key,
         DATE_TRUNC('week', f.return_date)::DATE AS week_start,
         COALESCE(t.value::STRING, 'unclassified') AS theme,
         SUM(f.quantity) AS returned_units
  FROM voc.core.fba_returns f
  JOIN (SELECT DISTINCT product_key, asin FROM voc.core.product_map) pm
    ON pm.asin = f.asin,
       LATERAL FLATTEN(input => f.return_themes, OUTER => TRUE) t
  GROUP BY 1, 2, 3
),
sales AS (
  SELECT pm.product_key,
         DATE_TRUNC('week', d.sale_date)::DATE AS week_start,
         SUM(d.units_ordered) AS units_sold
  FROM voc.core.sales_daily d
  JOIN (SELECT DISTINCT product_key, asin FROM voc.core.product_map) pm
    ON pm.asin = d.asin
  GROUP BY 1, 2
),
theme_weeks AS (
  SELECT COALESCE(m.product_key, r.product_key) AS product_key,
         COALESCE(m.week_start, r.week_start) AS week_start,
         COALESCE(m.theme, r.theme) AS theme,
         COALESCE(m.mentions, 0) AS mentions,
         COALESCE(m.weighted_mentions, 0) AS weighted_mentions,
         COALESCE(r.returned_units, 0) AS returned_units
  FROM mentions m
  FULL OUTER JOIN returns r
    ON r.product_key = m.product_key
   AND r.week_start = m.week_start
   AND r.theme = m.theme
)
SELECT tw.product_key, tw.week_start, tw.theme,
       tw.mentions, tw.weighted_mentions, tw.returned_units,
       s.units_sold,
       tw.returned_units / NULLIF(s.units_sold, 0) AS theme_return_rate
FROM theme_weeks tw
LEFT JOIN sales s
  ON s.product_key = tw.product_key AND s.week_start = tw.week_start;

Three choices in this view keep returns from going missing. First, mentions and returns meet in a full outer join on product, week and theme, and sales join afterward on product and week. So if social posts in one week mention only lid problems, battery returns from that week still get their own row. Second, OUTER => TRUE keeps returns that have no comment or no theme, under the label unclassified. Third, one ASIN can map to several SKUs in product_map, so the view joins on distinct product and ASIN pairs, or returns and sales would be counted more than once. One caution: a comment can carry two themes, so theme rows can add up to more than the real number of returned units. For the total return rate, sum fba_returns directly instead of adding theme rows.

Next, build a semantic view on top of it. It tells Cortex Analyst what each column means and which columns are measures (Semantic views overview, CREATE SEMANTIC VIEW). Define at least four measures: theme mentions, like-weighted mentions, returned units by theme and return rate by theme. The dimensions are product, theme and week. Add synonyms too. Map "leak", "spill" and "cap" to lid_or_spill, so the agent understands the words that business users actually type.

The agent specification is YAML. The minimum is one Cortex Analyst tool on this semantic view. We add one custom tool that returns the most liked comments for a product and theme. The structure follows CREATE AGENT. The Cortex Agents documentation says custom tool parameters cannot use the object type, so keep parameters simple (Cortex Agents overview).

"Rises together" needs a precise meaning. The instructions tell the agent to compare the same week and the next one to four weeks of returns. Our own data shows why. Complaints and returns do not happen at the same time. The chart below shows the 17 product-problem comments by month.

The comparison video went up on 2025-07-27, and its 4 problem comments came 6, 44, 245 and 245 days later. The try-on video went up on 2026-01-20. Only 2 of its 13 problem comments came in the first week, and the rest spread from March to September. Both comments that mention a return came in March 2026, one 245 days after its video and one 52 days after.

Comment (author hidden)	Theme	Comment date	Days after video	Likes
Asks whether to open the lid from the top	Lid or spill	2026-01-20	0	79
Do not use the lid button, it breaks	Lid or spill	2026-01-22	2	5
Says everyone calls this blender terrible	General negative	2026-03-01	40	23
Returned it, weak on frozen fruit	Weak on ice	2026-03-13	52	97
Batteries do not last a full smoothie	Battery	2026-03-14	53	9
Both units came without the blade cap	Missing part	2026-07-31	192	0
Bought a second unit for a spare lid	Lid or spill	2026-09-12	235	0

This chart changes the Snowflake design in two ways. First, never pull a video only once. A pull in the first week only would have missed 3 problem comments on the first video. It would have missed 11 on the second. So the watchlist should pull the same videos every week or month, and the MERGE appends the new comments.

Second, a same-week join between complaints and returns will probably show nothing. Buyers use a product for a while before they complain and return it. Let the data find the lag. Do not assume it.

We must also be honest about volume. Two videos produced 17 problem comments over 14 months, so most weeks have zero. A correlation on data that sparse means nothing.

To give the agent a solid base, track 20 to 30 try-on style videos per product, plus Amazon reviews and return comments. Start with monthly grain and move to weekly when the data allows it. This limit comes from data volume, not from Snowflake, and any tool would have it. That is also why the instructions tell the agent to report weeks with missing data. An honest "too little data" is better than a trend invented from three comments.

What a month costs: API fees and Snowflake fees

Start with a concrete plan, then price it. One brand tracks 20 ASINs and 20 TikTok videos, and pulls reviews or comments for each once a day. It searches 5 Reddit keywords daily and 5 TikTok keywords weekly to find new videos. Over 30 days, that is 1,370 API calls. The API fee uses the catalog prices read on 2026-11-06, so it is a real price.

Every Snowflake line is an estimate, and the table shows the method. Prices come from the Service Consumption Table effective 2026-11-04 and the on-demand Standard edition price in AWS US East. A platform credit is $2.00. An AI credit is $2.00 at the global rate (Service Consumption Table, pricing page, Cortex AI pricing).

Item	Method	Per month
EveryInfra API fee	600 `amazon/reviews` × $0.001389 + 600 `tiktok/comments` × $0.000556 + 150 `reddit/search` × $0.000556 + 20 `tiktok/search` × $0.000556	$1.26
Warehouse waits for responses (sync, serial)	Measured durations: Amazon reviews 67.25 s (the slowest of our 5 calls, an empty result; with the 19.48 to 60.12 s of the 503 calls, this line is $24.61 to $38.16), TikTok comments 52.3 s, Reddit 7.62 s, TikTok search 3.78 s. Total 20.27 hours × 1 credit per hour on XS × $2	$40.54
Warehouse waits (sync, 10 parallel calls)	Same, divided by 10	$4.05
Warehouse (async, two tasks)	About 46 submits a day × 2 s, plus 2 collector runs at the 60 s minimum, plus 60 s of idle time before auto-suspend after each of 3 runs. About 392 s a day, or 3.3 hours a month	About $6.5
`AI_CLASSIFY` theme labels	10,000 comments × about 150 tokens = 1.5 million tokens × 1.62 AI credits per million × $2	$4.86
Cortex Agent questions (Sonnet 5.5)	50 questions × 20,000 input and 1,500 output tokens, at 1.30 input and 6.50 output AI credits per million	$3.58
Cortex Agent questions (Haiku 5.5)	Same, at 0.065 input and 0.325 output	$0.18
Agent SQL on the warehouse	50 queries × 60 s minimum × $2 per credit-hour	$1.67
Storage	1 GB at $23 per TB per month	About $0.02

The second row is the one to watch. The API itself costs $1.26 a month. But if the procedure uses the simplest code, one synchronous call after another, the warehouse runs for more than 20 hours a month. That is about $40.54, or 32 times the API fee. With 10 parallel calls or the async two-task design, this line drops to between $4 and $7.

Parallel calls are cheapest in our estimate, but you must manage threads and timeouts in Python yourself. The async design costs two or three dollars more. In return, no single request gets cut off for waiting too long, and a failed job simply runs again the next day. We prefer the async design.

In total, the serial design costs about $51.93 a month and the parallel design about $15.44. In the Singapore region, a Standard edition credit is $2.50, so multiply the warehouse lines by 1.25. On Enterprise edition, the US East on-demand price is $3.00 per credit, with the same scaling.

The model is the second lever. Cortex Agent orchestration bills by tokens, and the model prices in the consumption table differ a lot. For the same 50 questions, Sonnet 5.5 costs about $3.58 and Haiku 5.5 about $0.18. Opus 5.5 costs 2.60 per million input tokens and 13.00 per million output tokens, twice the Sonnet price. The table lists the prices that matter for this article, in AI credits per million tokens. AI functions bill on total tokens, without an input and output split.

Model or function	Input	Output	Use in this article
claude-sonnet-5-5 (CoWork, Agents)	1.30	6.50	Agent orchestration, default in the cost table
claude-haiku-5-5 (CoWork, Agents)	0.065	0.325	Low-cost orchestration
claude-opus-5-5 (CoWork, Agents)	2.60	13.00	Not needed for routine reports
openai-gpt-6.1-sol (CoWork, Agents)	1.30	6.50	Same price as Sonnet
`AI_CLASSIFY`	1.62 (total)		Theme labels for comments and return notes
`AI_SENTIMENT`	1.60 (total)		Optional sentiment score
`AI_AGG`	1.85 (total)		Optional summary of text by theme

The figure of 20,000 input tokens per question is our assumption. It covers the semantic view, the instructions and one or two rounds of tool results. If the agent calls tools many times in one chat, or reads long comments into its context, the real number goes up. After launch, the CORTEX_AGENT_USAGE_HISTORY view gives real numbers. CoWork questions appear in SNOWFLAKE_COWORK_USAGE_HISTORY, and neither view includes the requests of the other (Cortex Agent usage view, CoWork usage view).

Each outbound request from the procedure appears in the EXTERNAL_ACCESS_HISTORY view, which can lag by up to 3 hours (External access history). Match it by time against the charged_usd values in voc.raw.jobs, and you can check calls and spend on both sides each month. Snowflake also lets you set resource budgets per agent and quotas per user (Cortex Agents resource budgets). On the EveryInfra side, give this key its own per-minute call limit. With a limit on each side, a broken task cannot make tens of thousands of calls overnight.

One line in the consumption table is easy to misread. "Cortex Tools" charges 8 AI credits per 1,000 tool calls when third-party agents access non-Snowflake endpoints, and nothing for Snowflake endpoints. In our design, a Snowflake stored procedure calls the EveryInfra API, not an agent. The agent only reads Snowflake tables, so we did not include that line.

Suppose you switch to MCP connectors and let the agent call outside tools during chats. The documents do not say whether this line applies or how it counts. Ask your Snowflake account team before launch. A new account can try the whole setup on the trial: the pricing page lists 30 days and $400 of credits.

A weekly email with snowflake cowork automations

With the data and the agent in place, the last step is to put the answer in front of the right people on time. CoWork Automations do exactly that. You set a question to run on a schedule, for example every Monday at 09:00. A good question is "Which complaint theme rose with the return rate over the last four weeks?" The result arrives by email (Automations documentation).

Know the documented limits first. An automation runs at most once an hour. Results go only to email, and each recipient must verify an email address in Snowflake first. Run history stays for 60 days. Each automation runs with the rights of the person who created it, so any table that person can read can appear in the email.

Documented limit	Value	Effect on a weekly complaint report
Fastest schedule	Once an hour	No effect, the report is weekly
Delivery	Email only, verified addresses	Recipients must verify first
Run history	60 days	Keep the answers in a table if you need longer history
Rights	Creator's rights	The email can contain any table the creator can read
EXECUTE AGENT TASK	Granted to PUBLIC by default	Revoke and grant by role if needed

None of these limits blocks our use case. Complaints and returns are weekly topics, so hourly runs are more than enough. Email-only delivery means no direct Slack post. The press release says that Snowflake for Slack is now in public preview (Expedition 2026 press release).

The real watch point is access. The EXECUTE AGENT TASK privilege goes to the PUBLIC role by default, so anyone in the account can create an automation for themselves. An automation runs with its creator's rights. A person who can read all sales data can therefore send that data to any address they enter. If that is not acceptable, an admin should revoke the privilege from PUBLIC and grant it by role.

Limits of this test

Everything on the Snowflake side is a configuration example. We have no Snowflake account here, and we did not run this SQL, these procedures or this agent specification. The syntax follows docs.snowflake.com as read on 2026-11-06. Snowflake shipped a large release this month, so syntax and limits can still change. Run each block in your own account before you depend on it.

In the cost table, only the API fee is a real price. Every Snowflake line is an estimate from public prices and our assumptions. The two largest unknowns are the real token count per classified comment and the real token count per agent question.

On the data side, all 5 Amazon review calls failed to return reviews this time. So the theme analysis uses only 273 TikTok comments. One author labeled them by hand with the rule above, and nobody checked the labels a second time. The 17 problem comments are enough to say that lid and spill problems deserve attention. They are not enough to estimate the true problem rate of this product.

This article gives only the structure of the sales and returns tables, with no real or invented numbers. The answer to "which complaint theme rises with returns" arrives when your own data does.

One limit concerns EveryInfra itself. Our MCP server cannot be added as a Snowflake connector today, for the reasons above. The external access route does not depend on that, and it is the route we recommend. But if your team wants a one-click connection inside CoWork, that is not possible yet. We will check this status again when this article goes live.

How this differs from our earlier articles

Our earlier review articles kept the data inside an agent or a file: Claude Cowork scheduled tasks, Claude Managed Agents for nightly review checks, Qwen Agent MCP in practice and DeepSeek V4 in Claude Code for review cleaning. They answer "what are people complaining about lately". Here, reviews move into the company data warehouse, under the same access rules and business definitions as sales and returns, so the question becomes "which complaint actually costs us money". The price is one more warehouse bill and a set of tables, about fifteen dollars a month for one brand as computed above. If your sales and returns are not in Snowflake yet, the earlier approaches are lighter. If they are already there, this setup lets complaints meet the financial numbers for the first time.

Recent changes

On 2026-11-04, the new Snowflake Service Consumption Table took effect. All model prices, AI function prices and the "Cortex Tools" line in this article come from that version (Service Consumption Table).

On the same day, a release note added background runs to the Snowflake-managed MCP server. The CORTEX_AGENT_RUN and CODING_AGENT tools gained a background argument that returns a handle at once. Servers with those tools now get three extra tools automatically: ASYNC_AGENT_RUN_STATUS, ASYNC_AGENT_RUN_CANCEL and AGENT_RUN_RESULT. A new content_cel_filter parameter lets a client read an outline first, then only the parts it needs (November 4, 2026 release note).

FAQ: snowflake cortex agents mcp and snowflake cowork

Is the snowflake cortex agents mcp server the same thing as an MCP connector?

No. They point in opposite directions. Source: Google autocomplete for "snowflake cortex agents mcp server". The Snowflake-managed MCP server makes Snowflake the server. Outside clients call your agents, Cortex Search, Cortex Analyst and SQL through MCP. Its tool types are CORTEX_AGENT_RUN, CODING_AGENT, CORTEX_SEARCH_SERVICE_QUERY, CORTEX_ANALYST_MESSAGE, SYSTEM_EXECUTE_SQL and GENERIC. The documentation recommends OAuth over hard-coded tokens (Snowflake-managed MCP server, CREATE MCP SERVER).

An MCP connector makes Snowflake the client, so Cortex Agents and CoWork can call an outside MCP server, with OAuth only (connectors documentation). This article needs the second direction, and in the end it uses external access instead of MCP.

What is the difference between snowflake cowork and CoCo (Cortex Code)?

Source: Google autocomplete for "snowflake cowork vs coco". Per the press release of 2026-11-03, CoWork serves business users. They ask questions in plain language at ai.snowflake.com, open dashboards and set automations. CoCo serves developers and data engineers, who use it to write code and build data objects. Analysts can also describe a dashboard to CoCo to build it (Expedition 2026 press release, Cortex Code documentation).

In this article, data engineers build the tables, procedures and semantic view with CoCo or plain SQL. Business users ask questions and receive the weekly report in CoWork.

Can Cortex Agents call an outside API with an API key instead of OAuth?

Yes, but not through an MCP connector. Source: the follow-up question that the "OAuth only" line in the Snowflake connectors documentation raises. Store the key in a secret of type GENERIC_STRING through an external access integration. Write a Python stored procedure that calls the API, and add that procedure to the agent as a custom tool. When the agent calls it, the procedure runs on a warehouse and bills by warehouse time (external network access, Cortex Agents overview). We prefer a scheduled task that loads tables, so each question avoids an API wait.

Does AI_CLASSIFY work on comments that are not in English?

It works, but check it first. Source: the usage notes in the Snowflake AI_CLASSIFY documentation. The documentation says English input works best and other languages can perform worse (AI_CLASSIFY documentation). If you track Spanish-language or other markets, label about 100 comments by hand and compare. Where categories disagree, make the task description and examples more specific. You can also have a stronger model in Cortex Agents judge each comment, at a higher cost.

Does EveryInfra charge for failed or empty calls?

No. Source: the responses of our 12 live calls. Bad parameters, temporarily unavailable targets (status 503) and empty results are not charged, and every charged response states the exact amount. All 6 calls in this article that returned no data show charged_usd as 0. In async mode the charge happens at submit, and a job that fails later is refunded against the same charge.

Getting started

Sign up for EveryInfra and follow the quickstart. Create an API key only for Snowflake, with its own per-minute limit.
Call each product URL, video URL and keyword once with curl. Check the fields and row counts before you add targets to the watchlist table.
In Snowflake, create the network rule, secret and external access integration from the examples above. Then create the two procedures and two tasks.
After a few days of loads, build the weekly view and the semantic view. Label comments and return notes with the same AI_CLASSIFY themes.
Create the Cortex Agent and ask it a few questions in CoWork. When it reports missing weeks correctly, set the weekly automation.

All the data capabilities are listed in the EveryInfra catalog. The remote MCP setup is on the MCP server page, and per-call prices are on the pricing page.
