Install ModelLens for Cursor

Cursor reads ~/.cursor/mcp.json. A project can also commit .cursor/mcp.json.

Open ~/.cursor/mcp.json on macOS, %USERPROFILE%\.cursor\mcp.json on Windows, or ~/.cursor/mcp.json on Linux.
Paste the JSON config below.
Replace placeholder secrets, then restart the client if it does not reload on its own.
