Is Upstream reliable?

Reliable (measured) Yes. Faceabot measured Upstream 12 times: 100% of checks succeeded, including the last 12 in a row (last check 2026-10-19 15:40 UTC). Its real task worked 7 of 11 times.

Last check: 2026-10-19 15:40 UTC · answered in 9537 ms · remote (no install)

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

What it does

Does it actually do the job?

Partly does the job — Faceabot asked get_digest to do a small read-only task 11 time(s): 7 returned a real result, the last 1 in a row. Last result: ok in 3060 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.
