Which MCP servers actually work?

We track 49421 servers from the official MCP Registry. 32541 are hosted (remote); we have health-checked 32263 so far. 287 use templated URLs that need user-specific values and can't be checked. Of those checked, 17698 passed a full MCP handshake, 9022 are up but need credentials, and 5543 failed or were unreachable (last check 2026-10-24T07:15:11.966Z UTC). How we check.
