APS MCP Server

A minimal MCP server integrating Autodesk ACC APIs via APS toolkit.

Video Overview

Setup

Option 1: Using uv (recommended)

1. Install uv if you don't have it:

   curl -LsSf https://astral.sh/uv/install.sh | sh
   

2. Copy .env.sample to .env and fill in your credentials:

   cp .env.sample .env
   

3. Create and activate a virtual environment:

   uv venv
   # On Windows:
   .venv\Scripts\activate
   # On Unix or MacOS:
   source .venv/bin/activate
   

4. Install dependencies:

   uv pip install -r requirements.txt
   

5. Run the MCP server:

   python aps_dm_server.py
   

Option 2: Using pip

1. Copy .env.sample to .env and fill in your credentials:

   cp .env.sample .env
   

2. Create and activate a virtual environment:

   python -m venv .venv
   # On Windows:
   .venv\Scripts\activate
   # On Unix or MacOS:
   source .venv/bin/activate
   

3. Install dependencies:

   pip install -r requirements.txt
   

4. Run the MCP server:

   python aps_dm_server.py
   

Integration with Claude Desktop

To use this MCP server with Claude Desktop:

1. Make sure you have Claude Desktop installed (download from Claude.ai)

2. Open your Claude Desktop configuration file:

   code ~/Library/Application\ Support/Claude/claude_desktop_config.json
   

   Create it if it doesn't exist.

3. Add the appropriate configuration:

   Option A: Direct Python from virtual environment (most reliable)

   {
       "mcpServers": {
           "acc": {
               "command": "/ABSOLUTE/PATH/TO/YOUR/.venv/bin/python",
               "args": [
                   "/ABSOLUTE/PATH/TO/YOUR/aps_dm_server.py"
               ],
               "env": {
                   "PYTHONPATH": "/ABSOLUTE/PATH/TO/YOUR/PROJECT/FOLDER"
               }
           }
       }
   }

   Replace paths with absolute paths to your environment and project.

   Option B: Using uv

   {
       "mcpServers": {
           "acc": {
               "command": "/ABSOLUTE/PATH/TO/uv",
               "args": [
                   "--directory",
                   "/ABSOLUTE/PATH/TO/YOUR/PROJECT/FOLDER",
                   "run",
                   "aps_dm_server.py"
               ]
           }
       }
   }

   Find the absolute path to uv by running which uv in your terminal.

4. Save the file and restart Claude Desktop completely

5. Look for the hammer icon in Claude Desktop to access the ACC tools

macOS Specific Setup

macOS users may encounter permission issues when integrating with Claude Desktop:

1. Permission Issues: If you see errors like Operation not permitted in logs:

   • Open System Preferences → Privacy & Security → Full Disk Access
   • Add Terminal and Claude applications by clicking the "+" button

2. Working Directory Issues: If you see errors about current directory not existing:

   • Always use absolute paths in your configuration
   • Consider storing projects in locations with fewer permissions restrictions (e.g., Documents folder)

3. Finding the correct Python path: To get the exact path to your virtual environment's Python:

   source .venv/bin/activate  # Activate your environment first
   which python  # Get the full path
   

4. Checking logs for troubleshooting:

   tail -n 50 -f ~/Library/Logs/Claude/mcp*.log
   

Requirements

• Python 3.11 or higher
• Dependencies listed in requirements.txt

System Architecture

This MCP server acts as a bridge between Claude AI and the Autodesk APS platform. The diagram below illustrates how data flows through the system:

1. Your query to Claude triggers tool selection
2. Claude sends MCP requests to your local server
3. The MCP server connects to APS/ACC using your credentials
4. Data flows back to Claude which processes and formats results

Available Tools

The MCP server exposes the following tools:

• get_hubs: Get all available hubs
• get_projects: Get all projects within a hub
• get_project_files: Get files in a specific folder of a project
• get_versions: Get version information for a specific item

Troubleshooting

If you encounter issues with Claude Desktop integration:

1. Server not showing up:

   • Check configuration file syntax (valid JSON)
   • Use absolute paths everywhere
   • Restart Claude Desktop completely

2. Permission errors:

   • Grant Full Disk Access to Terminal and Claude
   • Try using Python directly rather than through uv
   • Try moving the project to a location with fewer restrictions

3. Environment errors:

   • Ensure all dependencies are installed
   • Try using the direct path to Python in your virtual environment
   • Check your .env file has correct Autodesk credentials

4. Logs check:

   tail -n 50 -f ~/Library/Logs/Claude/mcp*.log
   

5. Manual testing: Test your server works by running it directly:

   cd /path/to/your/project
   source .venv/bin/activate
   python aps_dm_server.py
   

Using with OpenAI Agents SDK

This project includes integration with the OpenAI Agents SDK, allowing you to use the MCP server with an OpenAI agent.

1. Make sure your .env file includes your OpenAI API key:

   OPENAI_API_KEY=your_openai_api_key
   

2. Install the additional dependencies:

   uv pip install openai>=1.31.0
   

3. Run the agent:

   python main_agent.py
   

This will start an interactive session where you can ask the agent questions about your Autodesk projects.
