MCP servers, called rather than listed

8,642 answer a handshake (51.1%)
4,068 gated, not broken (24.0%)
4,213 failed outright (24.9%)
130,518 tools indexed

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.
