## What it is
A Model Context Protocol (MCP) server and FreeCAD addon that lets Claude Desktop control FreeCAD for 3D CAD design tasks. It exposes FreeCAD operations over an RPC server so an LLM can create and manipulate 3D models conversationally.

## Use cases
- design a 3d part with claude
- control freecad from an llm
- generate cad models from a 2d drawing
- mcp server for freecad
- ai-assisted parametric modeling
- create a flange by chatting with claude

## When to choose
- you use FreeCAD and want LLM-driven CAD automation
- you want Claude Desktop to create or edit 3D models
- you want to prototype parts from descriptions or 2D drawings

## When to avoid
- you don't use FreeCAD or Claude Desktop
- you need fully deterministic, scriptable CAD without an LLM in the loop
- you need commercial CAD tool integration like SolidWorks
