OTRS MCP Server

A Model Context Protocol (MCP) server for OTRS (Open Ticket Request System) API integration.

This provides access to OTRS ticket management, configuration items, and other OTRS functionality through standardized MCP interfaces, allowing AI assistants to create, search, and manage tickets and configuration items.

Features

• Create, read, update, and search tickets
• Access ticket history and detailed information
• Manage configuration items (CMDB)
• Session management and authentication
• Configurable default values for tickets
• Docker containerization support
• SSL/TLS support with certificate verification options
• Provide interactive tools for AI assistants

The list of tools is configurable, so you can choose which tools you want to make available to the MCP client.

Prerequisites

OTRS Server Configuration

Before using this MCP server, you need to configure your OTRS instance:

Step 1: Access OTRS Admin Panel

• URL: https://your-otrs-server/otrs/index.pl?Action=Admin
• Login with your admin credentials

Step 2: Configure Web Services

1. Navigate to: System Administration → Web Services
2. Create or verify you have a webservice (e.g., "TestInterface") with these operations:
   • ✅ SessionCreate
   • ✅ TicketCreate
   • ✅ TicketGet
   • ✅ TicketSearch
   • ✅ TicketUpdate
   • ✅ TicketHistoryGet
   • ✅ ConfigItemGet
   • ✅ ConfigItemSearch

Step 3: Note Your Webservice URL

Your webservice URL should look like:

https://your-otrs-server/otrs/nph-genericinterface.pl/Webservice/YourWebserviceName

Step 4: Ensure User Permissions

Make sure your OTRS user has appropriate permissions for:

• Creating and updating tickets
• Accessing configuration items
• Using the Generic Interface

Usage

Docker (Recommended)

The easiest way to run otrs-mcp with Claude Desktop is using Docker. If you don't have Docker installed, you can get it from Docker's official website.

Using Pre-built Image

You can use the pre-built Docker image from GitHub Container Registry:

{
  "mcpServers": {
    "otrs": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "-e",
        "OTRS_BASE_URL=https://your-otrs-server/otrs/nph-genericinterface.pl/Webservice/TestInterface",
        "-e",
        "OTRS_USERNAME=your-username",
        "-e",
        "OTRS_PASSWORD=your-password",
        "-e",
        "OTRS_VERIFY_SSL=false",
        "-e",
        "OTRS_DEFAULT_QUEUE=Raw",
        "-e",
        "OTRS_DEFAULT_STATE=new",
        "-e",
        "OTRS_DEFAULT_PRIORITY=3 normal",
        "ghcr.io/yourusername/otrs-mcp-server:latest"
      ]
    }
  }
}

Building Locally

If you prefer to build the image locally:

# Clone the repository
git clone https://github.com/yourusername/otrs-mcp-server.git
cd otrs-mcp-server

# Build the Docker image
docker build -t otrs-mcp-server .

# Run the container
docker run --rm -i \
  -e OTRS_BASE_URL="https://your-otrs-server/otrs/nph-genericinterface.pl/Webservice/TestInterface" \
  -e OTRS_USERNAME="your-username" \
  -e OTRS_PASSWORD="your-password" \
  -e OTRS_VERIFY_SSL="false" \
  otrs-mcp-server

Running with UV

Alternatively, you can run the server directly using UV. First, set your environment variables:

export OTRS_BASE_URL="https://your-otrs-server/otrs/nph-genericinterface.pl/Webservice/TestInterface"
export OTRS_USERNAME="your-username"
export OTRS_PASSWORD="your-password"
export OTRS_VERIFY_SSL="false"
export OTRS_DEFAULT_QUEUE="Raw"
export OTRS_DEFAULT_STATE="new"
export OTRS_DEFAULT_PRIORITY="3 normal"
export OTRS_DEFAULT_TYPE="Unclassified"

Then edit your Claude Desktop config file and add the server configuration:

{
  "mcpServers": {
    "otrs": {
      "command": "uv",
      "args": [
        "--directory",
        "<full path to otrs-mcp-server directory>",
        "run",
        "src/otrs_mcp/main.py"
      ],
      "env": {
        "OTRS_BASE_URL": "https://your-otrs-server/otrs/nph-genericinterface.pl/Webservice/TestInterface",
        "OTRS_USERNAME": "your-username",
        "OTRS_PASSWORD": "your-password",
        "OTRS_VERIFY_SSL": "false"
      }
    }
  }
}

Note: if you see Error: spawn uv ENOENT in Claude Desktop, you may need to specify the full path to uv or set the environment variable NO_UV=1 in the configuration.

Environment Variables

Variable	Required	Default	Description
OTRS_BASE_URL	✅	-	Base URL for OTRS webservice
OTRS_USERNAME	✅	-	OTRS username
OTRS_PASSWORD	✅	-	OTRS password
OTRS_VERIFY_SSL	❌	false	Enable SSL certificate verification
OTRS_DEFAULT_QUEUE	❌	Raw	Default queue for new tickets
OTRS_DEFAULT_STATE	❌	new	Default state for new tickets

Development

Contributions are welcome! Please open an issue or submit a pull request if you have any suggestions or improvements.

This project uses uv to manage dependencies. Install uv following the instructions for your platform:

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

You can then create a virtual environment and install the dependencies with:

uv venv
source .venv/bin/activate  # On Unix/macOS
.venv\Scripts\activate     # On Windows
uv pip install -e .

Testing

Test your OTRS connection and API functionality:

# Set environment variables
export OTRS_BASE_URL="https://your-otrs-server/otrs/nph-genericinterface.pl/Webservice/TestInterface"
export OTRS_USERNAME="your-username"
export OTRS_PASSWORD="your-password"
export OTRS_VERIFY_SSL="false"

# Run connectivity test
uv run python tests/connectivity_test.py

# Run API functionality test
uv run python tests/test_working_api.py

# Run debug diagnostics
uv run python tests/debug_test.py

The project includes test scripts that help verify your OTRS configuration and API connectivity.

Run the tests with pytest:

# Install development dependencies
uv pip install -e ".[dev]"

# Run the tests
pytest

# Run with coverage report
pytest --cov=src --cov-report=term-missing

Alternative: Docker Hub

To publish to Docker Hub instead:

# Login to Docker Hub
docker login

# Tag for Docker Hub
docker tag otrs-mcp-server yourusername/otrs-mcp-server:latest
docker tag otrs-mcp-server yourusername/otrs-mcp-server:v0.1.0

# Push to Docker Hub
docker push yourusername/otrs-mcp-server:latest
docker push yourusername/otrs-mcp-server:v0.1.0

Then update the Claude Desktop config to use:

Troubleshooting

Common Issues

1. SSL Certificate Errors: Set OTRS_VERIFY_SSL=false for self-signed certificates
2. HTTP 301 Redirects: Ensure you're using HTTPS URLs if your OTRS server redirects HTTP to HTTPS
3. Authentication Failures: Verify your username, password, and webservice configuration
4. Missing Operations: Check that your OTRS webservice includes all required operations

Debug Mode

Run the debug script to diagnose connection issues:

uv run python tests/debug_test.py

This will test both HTTP and HTTPS connections and provide detailed error information.

export OTRS_VERIFY_SSL="false"
export OTRS_DEFAULT_QUEUE="Raw"
export OTRS_DEFAULT_STATE="new"
export OTRS_DEFAULT_PRIORITY="3 normal"
