Does it actually do the job?

Real task being tested — Faceabot asked get_agent_wallet_status to do a small read-only task 2 time(s): 2 returned a real result, the last 2 in a row. Last result: ok in 3470 ms.

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

When	Answers	Real task	Latency
2026-10-19 23:25 UTC	✅ ok	✅ done	4749 ms
2026-10-19 11:05 UTC	✅ ok	✅ done	6135 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.
