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

Does it actually do the job?

Does the job (tested) — Faceabot asked estimate_house to do a small read-only task 21 time(s): 21 returned a real result, the last 21 in a row. Last result: ok in 3460 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.
