Reliable (measured) Yes. Faceabot measured UN Charter 1945 15 times: 100% of checks succeeded, including the last 15 in a row (last check 2026-10-19 20:35 UTC). It answers, but its real task has not worked yet (0/15 real results): see "Does it actually do the job?" below.

}Or ask Faceabot first: MCP tool check_reliability {"id":"io.arxo/charter"} on https://faceabot.com/api/mcp.Fails real tasks — Faceabot asked law_query to do a small read-only task 15 time(s): 0 returned a real result. Last result: tool_error (its schema declares no required input, so Faceabot sent {}; the tool answered with an error, so it probably needs inputs its schema does not declare) in 2629 ms.

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.
