  • A Kimai instance with API access enabled
  • API token from your Kimai user profile

Install the Package

# Clone the repository
git clone https://github.com/glazperle/kimai_mcp.git
cd kimai_mcp

# Install the package
pip install -e .

Alternative: Install Dependencies Only

pip install mcp httpx pydantic python-dotenv

Configuration

Getting Your Kimai API Token

  1. Log into your Kimai instance
  2. Go to your user profile (click your username)
  3. Navigate to the "API" or "API Access" section
  4. Create a new API token or copy an existing one
  5. Note your Kimai instance URL (e.g., https://kimai.example.com)

Claude Desktop Integration

Step 1: Configure Claude Desktop

Add the Kimai MCP server to your Claude Desktop configuration file:

On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

On Windows: %APPDATA%\Claude\claude_desktop_config.json

Step 2: Add Configuration

Add the following to your Claude Desktop configuration:

{
  "mcpServers": {
    "kimai": {
      "command": "python",
      "args": [
        "-m", "kimai_mcp.server",
        "--kimai-url=https://your-kimai-instance.com",
        "--kimai-token=your-api-token-here"
      ]
    }
  }
}

Important Notes:

  • Replace https://your-kimai-instance.com with your actual Kimai URL
  • Replace your-api-token-here with your API token from Kimai
  • Optionally add --kimai-user=USER_ID for a default user ID

Step 3: Restart Claude Desktop

After saving the configuration file, restart Claude Desktop for the changes to take effect.

Alternative Configuration Methods

Method 1: Using a .env File (Recommended for Development)

If you prefer using a .env file for configuration, create a .env file in your project directory:

# .env file in the kimai_mcp directory
KIMAI_URL=https://your-kimai-instance.com
KIMAI_API_TOKEN=your-api-token-here
KIMAI_DEFAULT_USER=1

Then use this Claude Desktop configuration:

{
  "mcpServers": {
    "kimai": {
      "command": "python",
      "args": ["-m", "kimai_mcp.server"],
      "cwd": "/path/to/your/kimai_mcp/directory"
    }
  }
}

Important Notes for .env Configuration:

  • Replace /path/to/your/kimai_mcp/directory with the actual path to your kimai_mcp directory
  • The cwd parameter ensures the .env file is found in the correct directory
  • Keep your .env file secure and never commit it to version control
  • On Windows, use forward slashes in the path or escape backslashes

Example Windows Path:

{
  "mcpServers": {
    "kimai": {
      "command": "python",
      "args": ["-m", "kimai_mcp.server"],
      "cwd": "C:/Users/YourName/Projects/kimai_mcp"
    }
  }
}
Method 2: Using Environment Variables (System-wide)

If you prefer system environment variables, you can set:

export KIMAI_URL="https://your-kimai-instance.com"
export KIMAI_API_TOKEN="your-api-token-here"
export KIMAI_DEFAULT_USER="1"  # Optional

Then use this Claude Desktop configuration:

{
  "mcpServers": {
    "kimai": {
      "command": "python",
      "args": ["-m", "kimai_mcp.server"]
    }
  }
}

Troubleshooting

Common Issues

Connection Problems
  1. Verify Kimai URL: Ensure your Kimai URL is correct and accessible
  2. Check API Token: Verify your API token is valid and not expired
  3. API Access: Ensure your Kimai instance has API access enabled
  4. Network: Check if there are any firewall or network restrictions
Permission Errors
  • Creating timesheets for other users requires admin permissions
  • Managing users and teams requires appropriate role permissions
  • Some absence operations require manager permissions
Configuration Issues
  1. Claude Desktop Config: Verify the JSON syntax is correct
  2. Path Issues: Ensure Python can find the kimai_mcp module
  3. Arguments: Check that command-line arguments are properly formatted

Debug Mode

For debugging, you can run the server directly:

# Using command line arguments
python -m kimai_mcp.server --kimai-url=https://your-kimai.com --kimai-token=your-token

# Using .env file (make sure you're in the directory with the .env file)
python -m kimai_mcp.server

# Test the package module execution
python -m kimai_mcp.server --help

Logging

The server includes comprehensive logging. Check the logs for detailed error information.

Security Considerations

  • API Token Security: Keep your API token secure and never commit it to version control
  • Network Security: Use HTTPS for your Kimai instance
  • Permission Management: Use appropriate Kimai roles and permissions
  • Regular Updates: Keep the MCP server and dependencies updated
