Creo MCP

An MCP (Machine-Collaboration-Platform) server with tools for CAD interaction and knowledge base retrieval. This project exposes several functions as tools that a larger agent or system can call, including interacting with Creo and querying a Volcengine knowledge base.

⚙️ Key Features

• CAD Integration: Opens .STEP files directly in Creo Parametric.

• Knowledge Base Retrieval: Connects to and queries a Volcengine knowledge base.

• Code Execution: Provides a tool to execute arbitrary Python code remotely.

• Command-Line Interface: Runs as a standalone server application with configurable credentials.

📦 Installation & Setup

Prerequisites

• Python 3.12 or newer

• uv package manager:

  • On macOS:

    brew install uv

  • On Windows (PowerShell):

    powershell -c "irm [https://astral.sh/uv/install.ps1](https://astral.sh/uv/install.ps1) | iex"

    You may need to add uv to your Path manually:

    # Add this line to your PowerShell profile
    $env:Path = "C:\Users\YOUR_USERNAME\.local\bin;" + $env:Path

  • For other systems, see the official uv installation instructions.

  ⚠️ Do not proceed before installing uv.

🌋 Volcengine Setup Guide

Follow these steps to retrieve the credentials required for the integration.

1. Navigate to the Knowledge Base. From the main Volcengine dashboard, select 知识库 (Knowledge Base) from the left-hand navigation menu.

2. Select Your KB. Click on the specific knowledge base you intend to use.

3. Create a New KB. Follow the following steps to create a new knowledge base:

   • Click the 创建知识库 (Create Knowledge Base) button.

   • Enter a name for your knowledge base and describption for it.

   • Click the 立即导入 (Import Now) button.

   • Import the three .jsonl files contained in the repository.

   • Click 导入 (Import) to complete the process.

4. Create a New Service Call. Follow the steps below to create a new service call:

   • Click the 知识检索 (Knowledge Retrieval) tab.

   • Click the 创建服务调用 (Create Service Call) button.

   • Enter a name for your service call and description for it.

   • Now you will choose the API key for the service call. This is the authentication key you will use in the next step.

5. Get the Service Resource ID. Follow the steps below to retrieve the service resource ID:

   • Click the 确认创建 (Confirm Creation) button.

   • Scroll down the Python 调用示例 (Python Call Example) section. You will find the Service Resource ID in the code snippet.

   • Copy the service resource ID and save it for later use.

   • Or you can click the 查看服务详情 (View Service Details) button to view the service resource ID.

Claude for Desktop Integration

1. Go to Claude > Settings > Developer > Edit Config > claude_desktop_config.json.

2. Add the following configuration to the mcpServers object:

   {
       "mcpServers": {
           "creo_mcp": {
               "command": "uvx",
               "args": [
                   "creo-mcp",
                   "--authorization",
                   "YOUR_TOKEN_HERE",
                   "--service-resource-id",
                   "YOUR_ID_HERE"
               ]
           }
       }
   }

   This allows Claude to automatically start your server when needed.

Cursor Integration

1. Go to Settings > MCP in Cursor.

2. Add a new server configuration.

   • For macOS: Use "add new global MCP server" or create a .cursor/mcp.json file in your project with the following content:

     {
         "mcpServers": {
             "creo_mcp": {
                 "command": "uvx",
                 "args": [
                     "creo-mcp",
                     "--authorization",
                     "YOUR_TOKEN_HERE",
                     "--service-resource-id",
                     "YOUR_ID_HERE"
                 ]
             }
         }
     }

   • For Windows: Add a new server with the following settings:

     {
         "mcpServers": {
             "creo_mcp": {
                 "command": "cmd",
                 "args": [
                     "/c",
                     "uvx",
                     "creo-mcp",
                     "--authorization",
                     "YOUR_TOKEN_HERE",
                     "--service-resource-id",
                     "YOUR_ID_HERE"
                 ]
             }
         }
     }

⚠️ Only run one instance of the MCP server (either via Cursor or Claude Desktop), not both simultaneously.

▶️ Manual Execution

If you need to run the server manually for debugging, first install it locally:

# Clone the repo
git clone https://github.com/yangkunyi/creo-mcp.git
cd creo-mcp

# Create a virtual environment and install in editable mode
uv venv
source .venv/bin/activate
uv pip install -e .

Then, run the server with your credentials:

creo-mcp --authorization YOUR_TOKEN_HERE --service-resource-id YOUR_ID_HERE

🛠️ Available Tools

The following tools are exposed by the server for remote execution:

• execute_python_code: Executes a given string of Python code.

• open_file_in_cad: Imports a .STEP file into Creo and opens it.

• retrieve_from_knowledge_base: Performs a retrieval query against the configured Volcengine knowledge base.
