Which MCP servers actually work?

We track 52511 servers from the official MCP Registry. 34750 are hosted (remote); we have health-checked 34456 so far. 304 use templated URLs that need user-specific values and can't be checked. Of those checked, 20589 passed a full MCP handshake, 9899 are up but need credentials, and 3968 failed or were unreachable (last check 2026-10-29T11:25:27.586Z UTC). How we check.
