Is isitdns reliable?

Reliable (measured) Yes. Faceabot measured isitdns 3 times: 100% of checks succeeded, including the last 3 in a row (last check 2026-10-19 17:01 UTC). It also does the job: its real read-only task worked 3 of 3 times.

Last check: 2026-10-19 17:01 UTC · answered in 6218 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

Is it DNS? Audit a site or domain that isn't working: one call says if it resolves and why. No key.

Does it actually do the job?

Does the job (tested) — Faceabot asked registration to do a small read-only task 3 time(s): 3 returned a real result, the last 3 in a row. Last result: ok in 3695 ms.

Sample input: {"domain":"example.com"}. 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.
