Is Clinical Trial Tracker reliable?

Reliable (measured) Yes. Faceabot measured Clinical Trial Tracker 15 times: 100% of checks succeeded, including the last 15 in a row (last check 2026-10-19 18:45 UTC). It answers, but its real task has not worked yet (0/15 real results): see "Does it actually do the job?" below.

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

Or ask Faceabot first: MCP tool check_reliability {"id":"io.github.agentstructure/clinical"} on https://faceabot.com/api/mcp.
Does it actually do the job?

Fails real tasks — Faceabot asked search_clinical_trials to do a small read-only task 15 time(s): 0 returned a real result. Last result: tool_error (its schema declares no required input, so Faceabot sent {}; the tool answered with an error, so it probably needs inputs its schema does not declare) in 2878 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.
