Provides tools for interacting with Rhinoceros 3D and Grasshopper, enabling AI agents to generate NURBS geometry, run parametric Grasshopper definitions, manage layers, and capture viewport renderings.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@rhino-mcp Create a box in Rhino and capture the viewport."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
A Model Context Protocol (MCP) server that connects AI assistants (Google Antigravity, Claude Desktop, Cursor) directly with Rhinoceros 3D and Grasshopper.
Built for architects, B.Arch students, and parametric designers, enabling AI agents to programmatically generate freeform NURBS geometry, evaluate Grasshopper definitions, manipulate layers, and capture viewport renderings.
RhinoCommon & CPython 3 Support: Works with Rhino 7 (IronPython) and Rhino 8 (native CPython 3.9+).
Grasshopper Parametric Solving: Load .gh / .ghx definitions, feed dynamic slider parameters, compute solutions, and bake geometry into Rhino layers.
Live Fleet Registration: Automatically registers its dynamic port and PID with %LOCALAPPDATA%\AutodeskMCP\registry.json, enabling single-entry routing through autodesk-mcp.
Architecture & Freeform Tool Suite:
Document Inspection: Document units, layer hierarchies, object counts, active viewports.
3D NURBS Primitives: Boxes, spheres, cylinders, curves, and lofts.
Grasshopper Solver: Automated parameter sweeps and optimization.
Viewport Capture: Real-time snapshot of shaded/rendered viewport encoded to base64.
Related MCP server: rhino-mcp
Run PowerShell installer:
.\install.ps1Or copy rhino_mcp/ into your Rhino scripts directory:
%APPDATA%\McNeel\Rhinoceros\scripts\
In Rhino's command bar, run:
_-RunPythonScript "rhino_mcp/startup.py"When running, the autodesk-mcp Gateway auto-detects Rhino and routes rhino_* tools seamlessly.
Tool | Description |
| Retrieves active document name, units, layers, and viewports. |
| Constructs 3D primitives (box, sphere, cylinder, NURBS curve). |
| Executes a parametric Grasshopper definition with dynamic input parameters. |
| Captures the active Rhino 3D viewport into base64 image. |
