multiCAD-mcp
MCP server that lets AI assistants drive AutoCAD, ZWCAD, and BricsCAD from one interface.
What it does and how it connects
multiCAD-mcp is an MCP server that lets an AI assistant control AutoCAD, ZWCAD, GstarCAD, and BricsCAD from text instructions, through one interface. It works with Claude for Desktop, Cursor, VS Code, and any MCP-compatible client, using a COM-based architecture on Windows. The README examples range from drawing a red circle at given coordinates to plotting a function graph with labeled axes.
The server exposes 7 unified MCP tools covering 56 CAD commands: drawing shapes, block creation and management, layer management, entity manipulation, property changes, data extraction and export to Excel, view navigation, file handling for DWG, DXF, and PDF, and connection control. Block attributes can be read and written, and blocks can be created from entities or a user selection.
Requirements stated in the README are Windows, Python 3.10 or later, and one or more of the supported CAD applications installed. The README states the unified tool design dispatches multiple operations in a single call to reduce API overhead.
Alternatives
Compare side by side- MecAgent
A commercial desktop copilot that acts inside a live SolidWorks session, rather than an MCP server driving AutoCAD-family tools over COM.
- CodeToCAD
A code-first framework where one Python script federates to Build123D or Blender, rather than an MCP server driving a live CAD session.
- Backflip AI
A CAD copilot that rebuilds scans, photos, and drawings as parametric models in Fusion, rather than driving AutoCAD-family drafting commands.
- DraftAid
Turns finished 3D models into 2D fabrication drawings, rather than driving live drafting commands in AutoCAD-family tools.
- Hestus
An autocomplete plugin that suggests sketch constraints and dimensions inside Fusion as you draw, rather than an MCP server for AutoCAD-family commands.
