What is the CAiD MCP Server?

Validated 3D CAD modeling for AI agents via CAiD + CadQuery. 54 tools with geometry validation.

What you get

Every geometry operation is validated through CAiD's ForgeResult system, which tracks volume, surface area, and diagnostics. If a boolean silently fails (common with OCCT), the validation layer catches it and tells you why.

Once CAiD is connected, these are the calls the assistant has available:

  • Category — Count
  • primitives — 7
  • modify — 4
  • transforms — 4
  • booleans — 4
  • query — 6
  • view — 2
  • scene — 5
  • export — 5
  • heal — 3
  • assembly — 5
  • compound — 3

Configuration and credentials

  • Python 3.11+
