A Rhino 8 plugin connects geometry and Grasshopper workflows to an external MCP server. For Codex, 1 route is explicitly documented by the integration maintainer.
Rhino with its documented Python scripting environment; use a script or plugin to expose operations externally.
Can Codex control all of Rhinoceros?
The sources establish the capabilities listed above, not complete application coverage. Check each bridge’s limitations and your application version before starting.
Which setup should I use?
Choose a route that explicitly documents Codex and matches your environment. Start with the maintainer’s setup guide and a disposable project copy. Shared MCP support alone is listed as an inference.
