Which MCP servers actually work?

We track 51099 servers from the official MCP Registry. 33811 are hosted (remote); we have health-checked 33528 so far. 293 use templated URLs that need user-specific values and can't be checked. Of those checked, 20285 passed a full MCP handshake, 9500 are up but need credentials, and 3743 failed or were unreachable (last check 2026-10-27T09:05:14.537Z UTC). How we check.
