We track 48412 servers from the official MCP Registry. 31745 are hosted (remote); we have health-checked 31473 so far. 280 use templated URLs that need user-specific values and can't be checked. Of those checked, 17143 passed a full MCP handshake, 8721 are up but need credentials, and 5609 failed or were unreachable (last check 2026-10-22T11:45:23.005Z UTC). How we check.
