Which MCP servers actually work?

We track 54231 servers from the official MCP Registry. 36185 are hosted (remote); we have health-checked 35888 so far. 308 use templated URLs that need user-specific values and can't be checked. Of those checked, 21522 passed a full MCP handshake, 10398 are up but need credentials, and 3968 failed or were unreachable (last check 2026-11-01T07:15:28.740Z UTC). How we check.
