Which MCP servers actually work?

We track 46141 servers from the official MCP Registry. 29920 are hosted (remote); we have health-checked 29653 so far. 271 use templated URLs that need user-specific values and can't be checked. Of those checked, 16383 passed a full MCP handshake, 8074 are up but need credentials, and 5196 failed or were unreachable (last check 2026-10-19T01:45:40.327Z UTC). How we check.
