Is Business Days reliable?

Reliable (measured) Yes. Faceabot measured Business Days 12 times: 100% of checks succeeded, including the last 12 in a row (last check 2026-10-19 12:20 UTC). It answers, but its real task has not worked yet (0/12 real results): see "Does it actually do the job?" below.

Last check: 2026-10-19 12:20 UTC · answered in 8018 ms · remote (no install)

En français : Fiable (mesuré). Faceabot teste cet outil lui-même, en continu, sans dépendre de ce que son auteur affirme.

Does it actually do the job?

Fails real tasks — Faceabot asked list_public_holidays to do a small read-only task 12 time(s): 0 returned a real result. Last result: tool_error (the tool answered with an error for the neutral sample input) in 2341 ms.

Sample input: {"country":"US","year":1}. 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.
