SolidWorks MCP server

This is a helper that connects your AI assistant to SolidWorks on your own computer. You ask for a part or an assembly in plain words, and the AI builds it in the SolidWorks window that is already open. It is handy for designers and engineers who want to skip the repetitive first steps of modelling, or who want a second pair of hands for simple parts.

What this MCP server does

You describe a part or assembly to your AI, for example a plate with holes or a small bracket. The AI turns that into a series of steps and calls this helper for each one. The helper reaches into your open SolidWorks and creates the sketch, the extrude, the holes, or whatever is needed. After each step it measures the result, volume, mass and bounding box, and hands those numbers back to the AI. The AI compares them with what you asked for and can correct itself before showing you the part.

What you can do with it

• Create parametric parts such as plates, brackets, shafts, pipes, cones and lofts
• Add holes, counterbores, slots, ribs, fillets, chamfers, shells and patterns
• Build assemblies with mates and check for interference
• Model real ISO metric threads and use the Hole Wizard
• Engrave or emboss text on a face
• Export the result as STEP, STL or 3MF and take screenshots
• Work on existing parts: list, delete, suppress or reorder features, and import STEP files

Try asking your AI

• “Design a 100 x 80 x 8 mm mounting plate with a 16 mm centre bore, four counterbored M5 holes 12 mm from the corners and R5 corners. Check the volume against your own calculation, then export a fine STL.”
• “Make an M10 bolt 40 mm long with a real thread and send me the measured mass.”
• “Build a swept pipe 200 mm long, 20 mm diameter, with two 90 degree bends and R30 corners, then check the volume.”
• “Create a shelled vase by revolving a profile, then export it as 3MF for printing.”

What it gives back to you

After each modelling step you get the part in your SolidWorks window, plus numbers in the chat: volume, mass and bounding box measured from the actual geometry. The AI also tells you the names of the dimensions it used, like width at Sketch1, so the part stays editable. If a step cannot be done, you get a clear error message instead of broken geometry. At the end you can ask for a summary, a drawing, an export file or a screenshot.

Who it's for

Product designers, mechanical engineers, makers and anyone who already uses SolidWorks and wants an AI to handle the first drafts and simple parts.
