CAD-MCP Server

Example Use Cases

• 1

  Convert natural-language drawing instructions into CAD operations (draw lines, circles, arcs, rectangles, polylines).

• 2

  Automate CAD workflows including layer management, hatch filling, text annotation, and dimensioning in AutoCAD/GstarCAD/ZWCAD.

• 3

  Integrate CAD control into assistant/tooling workflows (Claude Desktop, Cursor, MCP Inspector) to produce or save DWG files programmatically.

Description

CAD-MCP is an MCP server that bridges natural language instructions and CAD automation, enabling users or agents to create and modify drawings (lines, circles, arcs, polylines, text, hatches, dimensions) programmatically. It supports multiple CAD packages (AutoCAD, GstarCAD/GCAD, ZWCAD), layer management, and saving DWG files. The server includes an NLP processor for parsing commands, color and keyword recognition, and integrates with tools like Claude Desktop, Cursor, and MCP Inspector. It is distributed with an MIT license and requires Windows with a supported CAD installation.
