Following this with interest - I'm an ex-SolidWorks AE and was recently trying to use FreeCAD (which I didn't get on with as it's very different to what I'm used to).
I found a FreeCAD MCP which I was driving with Claude Code and got mixed results. I was using it to do the tedious task of matching up a PCB design with specific LED positions to an enclosure design (having built a little util to design KiCAD PCBs using Claude https://github.com/edcs/kicad-yaml).
I've moved back to OnShape now, so it's great to see a new tool out there which connects to the tools I'm used to.
