SolidCraft is a Rust parametric CAD app that AI agents can model in via MCP

SolidCraft, an open-source parametric 3D CAD app written in pure Rust under Apache-2.0, runs on desktop, in the browser and through a built-in MCP server for AI agents. Its README says 75 of 76 public reference parts match reported volume, area, centre of mass and bounding box, while noting these checks don't prove full geometric equivalence.

• 75 of 76 public reference parts matched on volume, area and centre of mass
• An agent built the SELENE rover via MCP as 3,323 editable timeline steps
• Custom constraint solver uses exact placement plus Levenberg-Marquardt
• Builds for Windows, macOS, Linux and browser; 0.11–0.14 need a manual update
