MCP 服务器

SolidWorks MCP Server

Enables Claude to create and manipulate SolidWorks CAD models through natural language commands, automating part creation, sketching, and extrusion.

README

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

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

Available Tools

The MCP server provides these tools to Claude:

Tool	Description
`solidworks_create_sketch`	Create a new sketch on Front, Top, or Right plane
`solidworks_sketch_rectangle`	Draw a rectangle with specified corner coordinates
`solidworks_sketch_circle`	Draw a circle with center point and radius
`solidworks_create_extrusion`	Extrude the current sketch to create a 3D feature
`solidworks_exit_sketch`	Exit sketch editing mode

Testing

Run the included test script to verify your setup:

python test_solidworks.py

This will:

Connect to SolidWorks
Create a new part
Draw a 100mm x 100mm rectangle
Extrude it 100mm to create a cube

If successful, you'll see a cube in SolidWorks!

Troubleshooting

SolidWorks doesn't launch

Ensure SolidWorks is installed and activated
Try launching SolidWorks manually first

"Failed to connect to SolidWorks"

Check that SolidWorks is running
Run Claude Desktop as Administrator
Verify pywin32 is installed: pip install pywin32

"No Part template found"

Check that SolidWorks templates exist at: C:\ProgramData\SOLIDWORKS\SOLIDWORKS 2024\templates\
Update the template path in server.py if your templates are elsewhere

Tool errors in Claude

Check the log file: solidworks_mcp.log
Restart Claude Desktop
Verify the config file path is correct
