> FreeCAD MCP leverages the Model Context Protocol (MCP) to bridge Claude AI with FreeCAD, enabling users to generate 3D models through natural language commands. By integrating directly with FreeCAD's Python API, the tool translates conversational input into precise operations within the PartDesign and Part workbenches. This open-source project, hosted on GitHub by contextform, automates complex CAD workflows and provides intuitive view controls via AI. It represents a significant advancement in human-computer interaction for engineering, allowing for seamless transition from text to 3D geometry.

# FreeCAD MCP

FreeCAD MCP leverages the Model Context Protocol (MCP) to enable natural language control of FreeCAD through Claude AI. This integration allows users to create 3D models, add features, and automate CAD workflows using conversational AI. The system connects Claude's terminal-based capabilities directly to the FreeCAD Python API to facilitate seamless automation and precise modeling operations.
