MCP Registry
A public MCP server list — every notable MCP server, graded A through F on OAuth conformance against RFC 7591, 7636, 8414, 8707, 9207, 9449, and 9728. Click any row for the detailed report.
All findings come from publicly observable metadata (the
/.well-known/* endpoints any MCP client reads). No
authenticated probes. To remove a server, open an issue.
