Between 1 and 3 October 2026 I filed the same three names into four public catalogs. None of those pull requests is merged. The software is already callable. The directories are not.
The three names are WARDEN (an MCP firewall for tool definitions), HISTOR (a signed log of what remote MCP servers advertised), and AIMarket Hub (the catalog they sit in). This is a status note, not a launch.
What was filed
| Where | When | What | State on 3 Oct 2026 |
|---|---|---|---|
| Docker MCP Registry #5364 | 1 Oct | WARDEN, local server, package 0.8.2 | Open |
| Docker MCP Registry #5365 | 1 Oct | Hub at https://modelmarket.dev/mcp
|
Open |
| awesome-erc8004 #120 | 1 Oct | Hub, HISTOR, WARDEN as ERC-8004 agents on Base | Open |
| coinbase/x402 #373 | 2 Oct | Six paid routes under Services/Endpoints | Open |
| Cline marketplace #2735 | 3 Oct | WARDEN server submission | Open |
An open pull request is a request. It is not a listing. If you search those catalogs today and the names are missing, that is the expected result.
What you can run without waiting for a merge
WARDEN is already on npm as @aimarket/warden 0.8.2. The Cline submission installs it like this:
"warden": { "command": "npx", "args": ["-y", "@aimarket/warden"] }
It scans advertised tool definitions — injection, exfiltration, secret requests — and records an allow or block before those definitions reach the model. It does not call the tools. Source: github.com/alexar76/warden (MIT). The Docker pull request pins the same version and lists nine tools, including vet_mcp_server and static_scan_tools.
The Hub's remote MCP endpoint is already up: https://modelmarket.dev/mcp. The Docker filing says the first calls per caller are free, and paid capabilities answer 402 with x402 terms after that. Tools are discovered from the server, not hardcoded in the pull request. Direct ones named in the filing: weather_now, air_quality_now, nearby_sensors, fair_random, plus market_search and market_invoke.
HISTOR is the record of what a remote MCP server advertised, not a verdict that the server is safe. The desk is histor.modelmarket.dev. Source: github.com/alexar76/histor.
The paid routes are live. The x402 directory page is not.
modelmarket.dev/a2mcp already lists six services. I read it on 3 October 2026. Two of them have a free HTTP path and a paid x402 path. Four are paid only.
| Service | Free path | x402 price |
|---|---|---|
| histor-check | yes | $0.001 |
| warden-scan | yes | $0.001 |
| weather-now | no | $0.001 |
| air-quality-now | no | $0.001 |
| fair-random | no | $0.006 |
| nearby-sensors | no | $0.03 |
The x402 pull request asks to add those routes to the ecosystem page. Until it merges, the page will not show them. The routes themselves do not wait on that page.
Settlement in the pull request goes through the CDP facilitator. That is a payment rail for those six URLs. It is not a claim that the Hub homepage is a busy market.
The on-chain IDs are published. The awesome-list is not.
modelmarket.dev/.well-known/agent-registration.json names three agents on Base, registry eip155:8453:0x8004A169FB4a3325136EB29fA0ceB6D2e539a432:
- AIMarket Hub — agent 96682
- HISTOR — agent 96683
- WARDEN — agent 96684
The awesome-erc8004 pull request is a README link to those IDs. Merging it changes a list. It does not create the agents. Leaving it open does not delete them either. A scan link from the pull request: 8004scan.io/agents/base/96682.
What I will not say until a maintainer clicks merge
- WARDEN is not in the Docker MCP catalog yet.
- The Hub is not in that catalog yet.
- AIMarket is not on the x402 ecosystem page yet.
- The three names are not in awesome-erc8004 yet.
- Cline has a submission issue, not a marketplace card.
The useful check is the thing you can call: the npm package, the MCP URL, the a2mcp list, the registration file. The catalogs are a paper trail. This week the paper is still in review.
