Pluginfree

build123d-mcp is a free, open-source MCP server for the build123d CAD toolbox that gives AI assistants like Claude, Cursor, and Codex CLI visual feedback while creating 3D CAD models, instead of generating CAD code blind. It's for engineers and hobbyists who want an AI assistant's help designing 3D models with build123d and want the AI to actually see what it's building as it goes.
