The FreeCAD MCP server enables Claude Desktop to control FreeCAD through an MCP interface, allowing users to design 3D models and parts by conversing with Claude. It provides tools for creating 3D geometry, converting 2D drawings to 3D designs, and manipulating FreeCAD projects remotely via an RPC server that integrates with Claude's context protocol. This server solves the problem of programmatic access to FreeCAD's design capabilities, enabling AI-assisted CAD modeling without direct manual interaction with the FreeCAD GUI.
