Connect your agent

{
  "mcpServers": {
    "guard": {
      "url": "https://karta.rta.lat/mcp"
    }
  }
}

Or ask Faceabot first: MCP tool check_reliability {"id":"lat.rta.karta/guard"} 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

When	Answers	Real task	Latency
2026-10-27 03:50 UTC	✅ ok	—	4725 ms
2026-10-26 17:01 UTC	✅ ok	—	7119 ms
2026-10-26 05:00 UTC	✅ ok	—	5331 ms

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.
