Reliable (measured) Yes. Faceabot measured Nubank MCP 12 times: 100% of checks succeeded, including the last 12 in a row (last check 2026-10-19 16:15 UTC). It answers, but its real task has not worked yet (0/12 real results): see "Does it actually do the job?" below.

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.
