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. The RhinoArtisan installer ships a small bridge for them, 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. 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.
