Search what these servers can do · read the measurement

Last checked 2026-09-06. We send a handshake, we do not authenticate and we do not call a tool.

Gated is not broken. 4,068 of these servers answer with a 401 or 403. They are running and want a credential we do not have. A checker that treats them as dead is wrong about 24.0% of the registry before it starts, so we count them separately and always will.

16,923 matching.
