Which MCP servers actually work?

We track 53360 servers from the official MCP Registry. 35490 are hosted (remote); we have health-checked 35196 so far. 305 use templated URLs that need user-specific values and can't be checked. Of those checked, 21108 passed a full MCP handshake, 10164 are up but need credentials, and 3924 failed or were unreachable (last check 2026-10-30T18:05:35.369Z UTC). How we check.
