FAQ

What is cadmcp?

An MCP server that bridges AI clients and CAD design tools. Agents call modeling tools over MCP; a dedicated executor runs the CAD side. SolidWorks 2025 on Windows is supported today; the protocol is built so additional CAD backends can follow the same surface.

Do I need SolidWorks to try it?

No. Use --backend fake for install, client wiring, and offline checks on any OS. Real geometry in SolidWorks requires Windows, SolidWorks 2025 running, and --backend solidworks.

Which AI clients work?

Any MCP host that can spawn a stdio server or connect over Streamable HTTP — including Cursor, Claude Desktop, VS Code, and OpenCode. Use cadmcp install --client … for common editors.
