Is Slashtel reliable?

Flaky Partly. Faceabot measured Slashtel 19 times and only 95% of checks succeeded. Plan a fallback. It also does the job: its real read-only task worked 18 of 18 times.

Does it actually do the job?

Does the job (tested) — Faceabot asked list_esim_destinations to do a small read-only task 18 time(s): 18 returned a real result, the last 18 in a row. Last result: ok in 3708 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.
