Original README from TheKingHippopotamus/GOLEM-3DMCP-Rhino-
<em>"Shaped from clay, brought to life by words"</em>
<strong>The most powerful MCP server for Rhinoceros 3D — 105 tools giving AI full read/write access to Rhino 8.</strong>
GOLEM-3DMCP implements the Model Context Protocol to give AI agents direct, programmatic control of Rhino 8 — create geometry, run booleans, drive Grasshopper, capture viewports, and execute arbitrary Python scripts, all through natural language.
Works with Claude Code, Cursor, Windsurf, and any MCP-compatible host.
Demo — A City Built Entirely by AI
An entire city generated in Rhino 8 through GOLEM-3DMCP — roads, skyscrapers, houses, trees, people, vehicles, a stadium, bridge, ferris wheel, harbor, wind turbines, and a floating GOLEM hologram. All created by Claude Code using natural language commands.

<em>Full city overview — ground, roads, buildings, park, harbor, sky</em>
<em>Skyline view — skyscrapers, bridge, wind turbines, floating GOLEM hologram</em>
<em>Close-up — GOLEM monument plaza, residential buildings, fountain</em>
<em>Street level — vehicles, people, street lamps, stadium, harbor with boats</em>
Install
pip install golem-3dmcp
That's it. Three commands to go from zero to AI-powered Rhino:
# 1. Install
pip install golem-3dmcp
# 2. Deploy the Rhino plugin (one-time)
golem install-rhino
# 3. Verify everything works
golem doctor
