rook-release is a Claude Code marketplace and release repo for Rook, an MCP bridge that lets AI assistants operate Rhino 3D and Grasshopper models through guided skills and tools.
About
rook is a Claude Code marketplace entry for Rook, which gives AI assistants direct access to Rhino 3D and Grasshopper through a large MCP tool surface. You describe tasks and Rook executes geometry, analysis, Python or C# Grasshopper scripts, layers, blocks, and BIM-oriented operations in your open model. Install it when computational design work should stay conversational yet grounded in the live Rhino document.
- Nearly 400 MCP tools for Rhino and Grasshopper workflows
- Windows installer wires Rook into Rhino plus MCP server setup
- Claude Code marketplace plugin adds guided skills and a session hook
- Local-first, bring-your-own-key privacy model per README
