Cursor XFMS — Model Source rank

How to: Cursor XFMS — Model Source rank

client:Cursor transport:streamable-http tool:rank

Add XFMS — Model Source to Cursor

01
Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "xfms": {
      "url": "https://xfms.vercel.app/mcp/"
    }
  }
}

02
Save the file and restart Cursor.
03
Ask for something rank does. Cursor lists the server's tools on connect and calls rank itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that XFMS — Model Source's identifier in your config matches the one above exactly.

Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
