We track 52412 servers from the official MCP Registry. 34671 are hosted (remote); we have health-checked 34377 so far. 304 use templated URLs that need user-specific values and can't be checked. Of those checked, 20603 passed a full MCP handshake, 9871 are up but need credentials, and 3903 failed or were unreachable (last check 2026-10-29T03:01:18.946Z UTC). How we check.
