Does it actually do the job?

Fails real tasks — Faceabot asked sellerprofit_checkup to do a small read-only task 14 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 3837 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.
