Or ask Faceabot first: MCP tool check_reliability {"id":"delivery.cometmessenger/courier"} on https://faceabot.com/api/mcp.

Does it actually do the job?

Fails real tasks — Faceabot asked recent_orders to do a small read-only task 13 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 5307 ms.

Sample input: {}. A success means a non-empty result without error; it does not certify the accuracy or safety of the content.

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.
