FreeCAD Parametric CAD Workflows with AI
TL;DR
- The FreeCAD MCP server lets agents create documents, add solids, edit dimensions, and export STL or STEP on your computer — FreeCAD stays open locally; geometry isn't modeled in the cloud.
- FreeCAD is open-source parametric CAD used for product design, maker projects, and mesh export — a practical fit when you want editable solids instead of one-shot mesh prompts.
- Built for makers and designers who already slice STLs or send STEP to a shop, and who'd rather describe a bracket or enclosure in chat than click through every sketch constraint alone.
Saturday morning at the bench. You need a simple enclosure base — 80×60×12 mm with four corner posts — before the printer finishes its current job. FreeCAD is already open on your Mac. You're in chat, not in the Part Design workbench, asking for the base plus an STL on your Desktop.
That's the loop: describe → model locally → export → slice. The FreeCAD integration on MCPBundles is for that loop when Desktop is running on the same machine.
