SolidWorks MCP Server

A Model Context Protocol (MCP) server that enables Claude to create and manipulate SolidWorks CAD models through natural language commands.

Overview

This MCP server bridges Claude AI with SolidWorks, allowing you to create 3D CAD models by simply describing what you want. Claude can create sketches, draw shapes, and extrude features directly in SolidWorks.

Features

• Automated Part Creation - Creates a new part document for each design request
• Sketch Creation - Create sketches on Front, Top, or Right planes
• Drawing Tools - Draw rectangles and circles with precise dimensions
• Extrusion - Extrude sketches into 3D features with custom depth
• Natural Language Interface - Describe what you want, and Claude builds it

Requirements

• Windows OS (SolidWorks only runs on Windows)
• SolidWorks 2022 or later (tested on SolidWorks 2024)
• Python 3.8+
• Claude Desktop App

Installation

1. Clone the Repository

git clone https://github.com/yourusername/solidworks-mcp.git
cd solidworks-mcp

2. Install Python Dependencies

pip install -r requirements.txt

requirements.txt:

mcp>=0.9.0
pywin32>=306

3. Configure Claude Desktop

Add the server to your Claude Desktop configuration file:

Location: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "solidworks": {
      "command": "python",
      "args": [
        "C:\\path\\to\\solidworks-mcp\\server.py"
      ]
    }
  }
}

Replace C:\\path\\to\\solidworks-mcp\\server.py with the actual path to your server.py file.

4. Restart Claude Desktop

Close and reopen Claude Desktop to load the MCP server.

Usage

Basic Examples

Create a simple cube:

Create a 100mm cube in SolidWorks

Create a cylinder:

Create a cylinder in SolidWorks with a 50mm radius and 200mm height

Create a rectangular prism:

Make a box in SolidWorks that's 150mm long, 75mm wide, and 50mm tall

How It Works

1. Claude creates a sketch on the specified plane (Front, Top, or Right)
2. Claude draws shapes (rectangles, circles) with your dimensions
3. Claude extrudes the sketch to create a 3D feature
4. A new part is created for each request automatically

Available Tools

The MCP server provides these tools to Claude:

Testing

Run the included test script to verify your setup:

python test_solidworks.py

This will:

1. Connect to SolidWorks
2. Create a new part
