Is HTTP 429 too-many-requests reliable?

Q: How do I connect an AI agent to HTTP 429 too-many-requests?

Use the MCP streamable HTTP endpoint https://agent-observatory-sensor.nolimit-observatory.workers.dev/s/http-429/mcp.

Not measured yet Not measured yet. Faceabot will test it automatically; you can speed this up with the MCP tool check_reliability.

En français : Pas encore mesuré. Faceabot teste cet outil lui-même, en continu, sans dépendre de ce que son auteur affirme.

Connect your agent

{
  "mcpServers": {
    "http-429": {
      "url": "https://agent-observatory-sensor.nolimit-observatory.workers.dev/s/http-429/mcp"
    }
  }
}

Or ask Faceabot first: MCP tool check_reliability {"id":"io.github.sadri-dridi/http-429"} on https://faceabot.com/api/mcp.

Does it actually do the job?

Not tested with a real task yet. Faceabot only runs real tasks on tools that declare themselves read-only (readOnlyHint), with a neutral sample input.

Faceabot measurements

No measurement yet.

Method: MCP initialize then tools/list from Faceabot (FaceabotProbe/1.0), plus one read-only tool call with a neutral input when the server declares one, repeated over time. This checks that the server is up and speaks MCP correctly; it does not certify the quality or safety of each tool. How measurement works.
