SolidWorks MCP Server (906grown edition)

Control SolidWorks with plain English through Claude, using the Model Context Protocol (MCP).

Created by 906grown. Built on the original SolidWorks MCP Server by Samsaam Ali Baig (MIT License).

This edition adds 23 new tools (48 total), a one-click Windows installer, SolidWorks 2026 / 3DEXPERIENCE support, and the ability for Claude to see the model with screenshots.

Requirements

• Windows 10 or 11

• SolidWorks 2023 to 2026 (installed and licensed), including SOLIDWORKS 3DEXPERIENCE R2026x

• Python 3.10 or newer (python.org, check "Add python.exe to PATH" during install)

• The Claude desktop app

Install (easy way)

1. Download this repo (green Code button > Download ZIP) and unzip it somewhere permanent, like Documents\solidworks-mcp.

2. Double-click INSTALL.bat. It installs the Python packages, checks the server loads, and adds it to Claude's config (your old config is backed up first).

3. Fully quit Claude (system tray > Quit) and reopen it.

4. Open SolidWorks, then ask Claude: "Connect to SolidWorks and tell me the version."

Using Claude to install it? Point it at SETUP_FOR_CLAUDE.md.

Manual install

pip install -r requirements.txt

Then add this to %APPDATA%\Claude\claude_desktop_config.json (use your real path):

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

Tools

Original tools (25)

New in the 906grown edition (23)

Every new tool was tested live against SOLIDWORKS 2026 (API v34).

Example prompts

• "Make a new part, sketch a 30 mm circle on the front plane and extrude it 15 mm."

• "Take an isometric screenshot so I can see it."

• "I selected a hole. What's its diameter?"

• "Sweep a 6 mm round profile along a curved path from (0,0,0) up 40 mm and over 20 mm."

• "List the dimensions and change the socket diameter to 12 mm."

Notes

• execute_python runs any Python code on your computer with access to SolidWorks. Only approve it when you know what it's doing.

• Logs go to solidworks_mcp/solidworks_mcp.log (ignored by git).

• If SolidWorks isn't auto-detected, set exe_path in solidworks_mcp/config.json to your SLDWORKS.exe.
