Claude Desktop XFMS — Model Source discover

How to: Claude Desktop XFMS — Model Source discover

client:Claude Desktop transport:streamable-http tool:discover

Add XFMS — Model Source to Claude Desktop

01
Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "xfms": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://xfms.vercel.app/mcp/"
      ]
    }
  }
}

02
Save the file and restart Claude Desktop.
03
Ask for something discover does. Claude Desktop lists the server's tools on connect and calls discover 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.

Claude Desktop has no remote transport in its config file, so this bridges through mcp-remote. Restart the app after saving. Claude Desktop 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.
