Ankus Drive MCP Server

A CLI + MCP server that drives FreeCAD through its Python API so LLMs (and humans at a terminal) can design mechanical parts and run FEM simulations without clicking through the GUI. It runs locally over stdio via the published package.

People who work with cad, cfd and fem and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

What is Ankus Drive?

A CLI + MCP server that drives FreeCAD through its Python API so LLMs (and humans at a terminal) can design mechanical parts and run FEM simulations without clicking through the GUI. It runs locally over stdio via the published package.
