Motivation and Context

Add a CAD MCP Server：Drawing CAD(Line,Circle,Text,Annotation...) through MCP server, supporting mainstream CAD software.

How Has This Been Tested?

Test basic functions through MCP Inspector
Drawn test drawings, such as rooms and animals through Claude Desktop and Windsurf。

Breaking Changes

Need to update client config

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update

Checklist

• I have read the MCP Protocol Documentation
• My changes follows MCP security best practices
• I have updated the server's README accordingly
• I have tested this with an LLM client
• My code follows the repository's style guidelines
• New and existing tests pass locally
• I have added appropriate error handling
• I have documented all environment variables and configuration options

Additional context

CAD-MCP Server (CAD Model Control Protocol Server)

Project Introduction

CAD-MCP is an innovative CAD control service that allows controlling CAD software for drawing operations through natural language instructions. This project combines natural language processing and CAD automation technology, enabling users to create and modify CAD drawings through simple text commands without manually operating the CAD interface.

Features

CAD Control Functions

• Multiple CAD Software Support: Supports mainstream CAD software including AutoCAD, GstarCAD (GCAD) and ZWCAD
• Basic Drawing Functions:
  • Line drawing
  • Circle drawing
  • Arc drawing
  • Rectangle drawing
  • Polyline drawing
  • Text addition
  • Pattern filling
  • Dimension annotation
• Layer Management: Create and switch layers
• Drawing Save: Save the current drawing as a DWG file

Natural Language Processing Functions

• Command Parsing: Parse natural language instructions into CAD operation parameters
• Color Recognition: Extract color information from text and apply it to drawing objects
• Shape Keyword Mapping: Support recognition of various shape description words
• Action Keyword Mapping: Recognize various drawing and editing actions

Demo

The following is the demo video.

Installation Requirements

Dependencies

pywin32>=228    # Windows COM interface support
mcp>=0.1.0      # Model Control Protocol library
pydantic>=2.0.0 # Data validation
typing>=3.7.4.3 # Type annotation support

System Requirements

• Windows operating system
• Installed CAD software (AutoCAD, GstarCAD, or ZWCAD)

Configuration

The configuration file is located at src/config.json and contains the following main settings:

{
    "server": {
        "name": "CAD MCP Server",
        "version": "1.0.0"
    },
    "cad": {
        "type": "AutoCAD",  
        "startup_wait_time": 20,
        "command_delay": 0.5
    },
    "output": {
        "directory": "./output",
        "default_filename": "cad_drawing.dwg"
    }
}

• server: Server name and version information
• cad:
  • type: CAD software type (AutoCAD, GCAD, GstarCAD, or ZWCAD)
  • startup_wait_time: CAD startup waiting time (seconds)
  • command_delay: Command execution delay (seconds)
• output: Output file settings

Usage

Starting the Service

python src/server.py

Claude Desktop & Windsurf

# add to claude_desktop_config.json. Note: use your path  
{
    "mcpServers": {
        "CAD": {
            "command": "python",
            "args": [
                # your path, e.g.: "C:\\cad-mcp\\src\\server.py"
                "~/server.py"
            ]
        }
    }
}

Cursor

# Add according to the following diagram Cursor MCP. Note: use your path  

MCP Inspector

# Note: use your path  
npx -y @modelcontextprotocol/inspector python C:\\cad-mcp\\src\\server.py

Service API

The server provides the following main API functions:

• draw_line: Draw a line
• draw_circle: Draw a circle
• draw_arc: Draw an arc
• draw_polyline: Draw a polyline
• draw_rectangle: Draw a rectangle
