Other MCP clients

Any client that supports the MCP streamable HTTP transport can connect to:

http://127.0.0.1:9280/mcp

Clients that only launch stdio servers

Some clients (Claude Desktop among them) only start local stdio servers. For Claude Desktop, use the downloadable connector on Windows or Mac. For other clients on Windows, the RhinoArtisan installer ships a small bridge, ArtisanMcpBridge.exe, in the MCP folder of the installation — usually C:\Program Files\RhinoArtisan 7\MCP\. It needs nothing else on the machine, and it keeps the client connected while Rhino is closed: the tools appear as soon as Rhino starts.

{
  "mcpServers": {
    "RhinoArtisan": {
      "command": "C:\\Program Files\\RhinoArtisan 7\\MCP\\ArtisanMcpBridge.exe",
      "args": ["http://127.0.0.1:9280/mcp"]
    }
  }
}

The bridge also accepts --port 9281 instead of a full URL. It is a Windows program: on Mac — or if you would rather not depend on the installer’s copy — the mcp-remote adapter does the same job but needs Node.js:

{
  "mcpServers": {
    "RhinoArtisan": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "http://127.0.0.1:9280/mcp"]
    }
  }
}

Once connected, test it with Rhino open:

“Create a round 1 ct diamond.”

Not working? See Troubleshooting.

Using a different port? If Rhino printed another address when you ran ArtisanMcpStart Port=…, use that one instead of http://127.0.0.1:9280/mcp. See Changing the port.
