SolidWorks MCP

Clone the SolidWorks MCP repository from GitHub. All source files and the entry point script are included.

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

Install the required Python packages using pip. The requirements file includes the MCP SDK and the pywin32 package for COM API access.

pip install -r requirements.txt

Launch SolidWorks before starting the MCP server. The server connects to a running SolidWorks instance via the COM API — it cannot start SolidWorks itself on first use.

Add the server to your claude_desktop_config.json file. Update the path to match where you cloned the repository. The config file is at C:\Users\YOUR_NAME\AppData\Roaming\Claude\claude_desktop_config.json.

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

Restart Claude Desktop after saving the config. In the Claude chat window, type 'Connect to SolidWorks' to use the connect_solidworks tool and establish the COM API connection.

Edit solidworks_mcp/config.json to change the default unit system, startup timeout, extrude depth, fillet radius, or log verbosity. The exe_path defaults to auto-detection via the Windows registry.

{
  "exe_path": "auto",
  "default_unit": "mm",
  "startup_timeout": 120,
  "log_level": "INFO",
  "default_extrude_depth": 10.0,
  "default_fillet_radius": 2.0
}
