About FreeCAD

FreeCAD MCP allows users to control FreeCAD 3D modeling software from other applications such as Claude Desktop. Enables parametric design and automation through RPC, including creating/editing/deleting objects, inserting parts from the FreeCAD library, executing arbitrary Python code, retrieving object information, and capturing screenshots of the active view.
