RhinoMCP

Model geometry and build Grasshopper definitions in Rhino 3D by chatting with Claude or Cursor.

Sources and review

Checked against public documentation on September 23, 2026. Suitability guidance is our editorial judgment; this is not a performance benchmark or an endorsement.

Repository and README

Best for

Designers and architects who want to prototype geometry and Grasshopper logic by prompt.

Avoid if

You can't install the Rhino plugin; the server works through its bridge.

About RhinoMCP

RhinoMCP connects Rhino and Grasshopper to AI agents over MCP. The assistant can model geometry, read the document, capture the viewport, and script Grasshopper by finding, wiring and solving components; for more control it can run native Rhino commands, RhinoScript-Python or RhinoCommon C#. A single Rhino plugin and config entry cover both.

RhinoMCP is an open-source project written primarily in Python, with 1.1k stars on GitHub. It was last updated in September 2026.
