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

#claude #api #ai #webscraping

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 Some of their claims are now out of date.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.)
