FreeCAD

Control FreeCAD from AI agents — 3D modeling, PartDesign workflows, CNC toolpaths, mesh operations, and file export via 32 tools.

FreeCAD bridges AI agents with the open-source FreeCAD parametric 3D CAD application. It provides 32 tools for part design and sketching, boolean operations, CNC toolpath generation, mesh operations, measurements, and manufacturing file export. The server runs locally alongside a FreeCAD installation and uses stdio transport.
