Sites with a working MCP server

639 sites built their own MCP server and it answered when we connected. Not registry entries — live endpoints on real sites, with the tools each one exposes. Platform-generated servers (Mintlify docs search, Teachify course catalogues) are on each site's own report, not here. How we test.
