A comprehensive FastMCP-powered server that enables AI assistants like Claude to interact with OpenProject installations. This implementation provides full project management functionality including user management, dynamic configuration, and advanced Gantt chart creation.

🎯 Core Features

MVP Functionality

• ✅ Create projects in OpenProject via AI assistant

• ✅ Create work packages with start/due dates for Gantt charts

• ✅ Create dependencies between work packages

• ✅ Generate proper Gantt charts in OpenProject

• ✅ End-to-end workflow from AI command to visual timeline

Phase 1 Enhanced Features

• ✅ User management - Find and assign users by email address

• ✅ Dynamic configuration - Automatically load types, statuses, and priorities

• ✅ Email-based assignment - Assign work packages without knowing user IDs

• ✅ Project member management - View project members and their roles

• ✅ Enhanced error handling - Detailed validation and error messages

🚀 Quick Start

Prerequisites

1. OpenProject Instance: You need a running OpenProject installation (local or cloud)

2. API Key: Generate an API key from your OpenProject profile

3. Python 3.8+: Required for running the MCP server

Installation

1. Clone or download the project:

   cd openproject-mcp-server

2. Create and activate virtual environment:

   python3 -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate

3. Install dependencies:

   pip install -r requirements.txt

4. Configure environment:

   cp env.example .env # Edit .env with your OpenProject details

Configuration

Edit the .env file with your OpenProject details:

Getting your OpenProject API Key:

1. Login to your OpenProject instance

2. Go to My Account → Access Tokens

3. Click + New token

4. Enter a name (e.g., "MCP Server")

5. Copy the generated 40-character token

Testing

Test your configuration before using with AI assistants:

This will:

• ✅ Test OpenProject API connection

• ✅ Create a test project

• ✅ Create work packages with dates

• ✅ Create dependencies

• ✅ Verify Gantt chart readiness

Running the Server

Start the MCP server:

The server will start and be ready to accept AI assistant connections.

🐳 Docker Deployment

Docker deployment is the recommended production method for the OpenProject MCP Server.

Prerequisites for Docker

1. Docker installed (version 20.10+)

2. Docker Compose (for easier management)

3. Configure with your OpenProject details

Quick Start with Docker

Option 1: Automated deployment (Recommended)

🔑 Important: The port MUST match your Claude Desktop MCP configuration in ~/.cursor/mcp.json or claude_desktop_config.json!

Option 2: Docker Compose (Alternative)

🔧 Port Configuration & Conflicts:

Step 1: Choose your port (must be consistent)

Step 2: Deploy on the SAME port as your MCP config

Step 3: If port conflicts occur:

• Stop conflicting services: docker stop container_using_port

• Or update BOTH MCP config AND deployment port consistently

• Check what's using port: docker ps | grep 39127

Manual Docker Commands

For advanced users who want full control:

1. Build the image:

   docker build -t openproject-mcp-server .

2. Run the container:

   docker run -d \ --name openproject-mcp-server \ --env-file .env \ -p 39127:8080 \ -v ./logs:/app/logs \ -v ./data:/app/data \ --restart unless-stopped \ openproject-mcp-server

3. Health check:

   # Check if container is healthy docker ps # View container logs docker logs openproject-mcp-server # Test API endpoint (Note: No health endpoint in MCP server) curl http://localhost:39127/sse

Deployment Script Commands

The scripts/deploy.sh script provides comprehensive deployment management:

💡 Port Selection Tips:

• Port 39127: Recommended MCP standard port, matches default config

• Port 8080: Default HTTP port, but often conflicts with OpenProject

• Port 9876: Good alternative, rarely conflicts

• Port 8090: Common development port

Environment Variables for Docker

When using Docker, configure these environment variables in your .env file:

Docker Deployment Best Practices

• Always use - Never hardcode credentials in commands

• Volume mapping - Map logs and data directories for persistence

• Health checks - Container includes built-in health monitoring

• Auto-restart - Use --restart unless-stopped for production

• Resource limits - Consider adding memory/CPU limits for production

🤖 AI Assistant Integration

Claude Desktop Integration

Add to your claude_desktop_config.json:

Option 1: Local Python execution

Option 2: Docker deployment (recommended)

Environment Setup: Configure OpenProject credentials in Docker deployment .env file instead of MCP config.

Important Notes:

• Use the full absolute path to the run_server.py script for Option 1

• Ensure the Docker container is running before using Option 2

• OPENPROJECT_URL should point to your OpenProject instance (typically port 8080)

• MCP server URL (port 39127) is configured separately in the transport URL

Usage Examples

Once integrated with Claude, you can ask:

Create a Project with Team Members

Create Work Packages with Email-based Assignment

Create Dependencies for Gantt Chart

User Management Examples

Dynamic Configuration Examples

The AI will use the enhanced MCP tools to create everything and you'll get a proper Gantt chart in OpenProject with proper user assignments!
