Why we included this project

Anyone who already lives in FreeCAD and wants a language model to take over the tedious parts of parametric modeling will find a working bridge here. The project exposes FreeCAD's internals, the open documents, objects, and active view, as MCP tools a model can call directly, so it can create a part, pull something from the parts library, run Python inside the session, or hand a model over to CalculiX for FEM analysis and come back with a screenshot of the viewport. You install an addon workbench on the CAD side that runs a local RPC server, and the MCP server installs separately, which keeps the two halves of the setup clean. Feedback defaults to images but can be switched to plain text, so it still works in headless or token-tight environments. If you are curious whether agentic CAD.
