About FreeCAD MCP

FreeCAD MCP lets MCP clients create and edit FreeCAD models, run Python scripts, inspect documents and run finite element analyses. It has two parts: an addon inside FreeCAD that starts an RPC server, and an MCP server launched by the client with uvx.

FreeCAD MCP is an open-source project written primarily in Python, with 2.5k stars on GitHub. It was last updated in September 2026.

Generated from the launch command in the project's README. Your client starts the server on demand.
