OpenProject MCP Server

A Model Context Protocol (MCP) server that provides seamless integration with OpenProject API v3. This server enables LLM applications to interact with OpenProject for project management, work package tracking, and task creation.

Features

• 🔌 Full OpenProject API v3 Integration
• 📋 Project Management: List and filter projects
• 📝 Work Package Management: Create, list, and filter work packages
• 🏷️ Type Management: List available work package types
• 🔐 Secure Authentication: API key-based authentication
• 🌐 Proxy Support: Optional HTTP proxy configuration
• 🚀 Async Operations: Built with modern async/await patterns
• 📊 Comprehensive Logging: Configurable logging levels

Prerequisites

• Python 3.8 or higher
• An OpenProject instance (cloud or self-hosted)
• OpenProject API key (generated from your user profile)

Installation

1. Clone the repository:

git clone https://github.com/yourusername/openproject-mcp.git
cd openproject-mcp

2. Create a virtual environment:

python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dependencies:

pip install -r requirements.txt

4. Copy the environment template:

cp .env.example .env

5. Edit .env and add your OpenProject configuration:

OPENPROJECT_URL=https://your-instance.openproject.com
OPENPROJECT_API_KEY=your-api-key-here

Configuration

Environment Variables

Getting an API Key

1. Log in to your OpenProject instance
2. Go to My account (click your avatar)
3. Navigate to Access tokens
4. Click + Add to create a new token
5. Give it a name and copy the generated token

Usage

Running the Server

python openproject-mcp.py

      "args": ["path/to/openproject-mcp.py"]
    }
  }
}

Available Tools

Troubleshooting

Connection Issues

1. 401 Unauthorized: Check your API key is correct and active
2. 403 Forbidden: Ensure your user has the necessary permissions
3. 404 Not Found: Verify the OpenProject URL and that resources exist
4. Proxy Errors: Check proxy settings and authentication

Debug Mode

Enable debug logging by setting:

LOG_LEVEL=DEBUG

Common Issues

• No projects found: Ensure your API user has project view permissions
• SSL errors: May occur with self-signed certificates or proxy SSL interception
• Timeout errors: Increase timeout or check network connectivity

Security Considerations

• Never commit your .env file to version control
• Use environment variables for sensitive data
• Rotate API keys regularly
• Use HTTPS for all OpenProject connections
• Configure proxy authentication securely if needed
