CAD-MCP

Why we included this project

CAD-MCP connects an LLM to desktop CAD applications through the Model Context Protocol, so a written instruction turns into an actual drawing command. It handles the drafting basics, lines, circles, arcs, rectangles, polylines, text, hatching, and dimension annotation, against AutoCAD, GstarCAD, or ZWCAD, and saves the finished drawing as a DWG file. The natural-language layer parses commands, pulls colors out of the text, and maps shape and action keywords, so a request like a red circle becomes a real object in the drawing instead of just an interpretation. It runs only on Windows and expects a licensed CAD install, which narrows the audience, but teams automating routine drafting work no longer have to hand-write every coordinate. The codebase is compact, a server plus the NLP and control logic, so adapting it to your own command vocabulary is fairly straightforward.
