Every remote server in the official MCP registry, sent one real
initialize handshake. 16,923 servers across
11,823 hosts.
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.
