Catalog › in.reqres/reqres

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

What it does

Hosted backend for AI agents: create projects with persistent collections and keys, no signup.

Connect your agent

{
  "mcpServers": {
    "reqres": {
      "url": "https://reqres.in/mcp"
    }
  }
}

Or ask Faceabot first: MCP tool check_reliability {"id":"in.reqres/reqres"} 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.

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.
