SolidWorks MCP

This project implements an MCP server that provides a powerful tool for generating SolidWorks automation scripts using Python and the pywin32 library. It leverages a Large Language Model (LLM) to interpret user requests and produce runnable Python code for creating parts and drawings in SolidWorks.

Features

• SolidWorks Automation: Generate Python scripts to automate tasks within SolidWorks.
• LLM-Powered Code Generation: Utilizes an LLM to translate natural language requests into pywin32 code.
• Easy Integration: Designed as a FastMCP server, allowing seamless integration with MCP-compatible clients and assistants.
• Timestamped Saving: Generated scripts include logic to save SolidWorks parts with unique, timestamped filenames.

How it Works

The solidgen tool exposed by this server takes a user request as input. It then constructs a detailed prompt for an LLM, instructing it to generate a Python script that uses pywin32 to perform the requested SolidWorks operation. The generated script includes boilerplate for initializing SolidWorks and saving the created part.

Getting Started

Prerequisites

• Python 3.x
• fastmcp
• pywin32
• Access to an LLM
• SolidWorks

Installation

1. Clone this repository:

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

2. Install dependencies using uv:

   uv sync
   

Running the Server

To run the FastMCP server:

python server.py

Once running, the server will expose the solidgen tool, which can be called by an MCP client.

Usage (via an MCP Client)

An MCP client can call the solidgen tool with a user_request string.

Example of how an MCP client might call the tool:

{
  "mcpServers": {
    "solidworks-mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "/ABSOLUTE/PATH/TO/PARENT/FOLDER/solidworks-mcp",
        "run",
        "server.py"
      ]
    }
  }
}

The tool will return a Markdown-formatted Python code block containing the generated SolidWorks automation script.
