## CLI Reference```bash



```bash### Production Installation as System Servicepoetry shell

deluge-mcp --help                    # Show help

deluge-mcp --version                 # Show version```

deluge-mcp install [--verbose]      # Install systemd service

deluge-mcp uninstall [--verbose]    # Remove systemd service  To install as a systemd service that survives restarts:

deluge-mcp status [--logs]          # Check service status

deluge-mcp run [OPTIONS]            # Run server directly## Usage



# Run command options:```bash

#   --transport {stdio,http}         # Transport mode (default: stdio)

#   --port INTEGER                   # HTTP port (default: 58880)# Install the package first (in user environment)### Running the MCP Server

#   --host TEXT                      # Bind address (default: 0.0.0.0)

#   --verbose                        # Enable debug loggingpip install .

```

Run the server directly in HTTP streamable mode:

## System Integration

# Install as system service (MUST use sudo)

### Systemd Service

The installed service includes:sudo deluge-mcp install```bash

- **Dependencies**: Waits for network and deluge daemon

- **Logging**: All output captured in systemd journal```deluge-mcp run

- **Security**: Minimal privileges with filesystem protection

- **Reliability**: Auto-restart on failures```

- **Root Access**: Required for system-wide torrent management

**What the installation does:**

### Network Access

- **Local**: `http://localhost:58880/mcp`1. Verifies root privileges and Ubuntu/Debian systemOr with a custom port:

- **Remote**: `http://YOUR_IP:58880/mcp` (if firewall allows)

- **Protocols**: HTTP with SSE, stdio for local clients2. Checks for `deluge-console` availability



## Troubleshooting3. Creates a dedicated virtual environment at `/opt/deluge-mcp/venv````bash



### Service Issues4. Installs deluge-mcp and all dependencies in the service venvdeluge-mcp run --port 8080

```bash

# Check service status5. Creates log directory at `/var/log/deluge-mcp````

sudo systemctl status deluge-mcp

6. Creates systemd service file configured for:

# View recent logs

sudo journalctl -u deluge-mcp -n 50   - Running as rootThe server will start and listen for MCP connections over HTTP.



# Follow logs in real-time   - Using the dedicated venv

sudo journalctl -u deluge-mcp -f

   - SSE transport on port 58880### Available MCP Tools

# Restart service

sudo systemctl restart deluge-mcp   - Comprehensive logging to files and systemd journal

```

   - Auto-restart on failureOnce the server is running, AI assistants can use the following tools:

### Common Problems

7. Enables and starts the service

**Service fails to start**:

- Ensure deluge-console is installed: `which deluge-console`#### 1. `get_running_torrents`

- Check Python version: `python3 --version` (needs 3.12+)

- Verify installation: `deluge-mcp status --verbose`## Usage



**Permission denied**:Get information about all torrents currently in Deluge.

- Service runs as root for system access

- Installation requires sudo for system directories### Running the Server

- Use `deluge-mcp install` (not `sudo deluge-mcp install`)

**Returns**: Detailed information including torrent names, states, progress, 

**Port conflicts**:

- Default port 58880 may be in use#### Stdio Mode (default)download/upload speeds, seeds, peers, and ETA.

- Change with: `deluge-mcp run --port 8080`

- Service port configured in systemd file```bash

  "magnet_url": "magnet:?xt=urn:btih:..."```

}

Output: "Torrent added successfully!## Architecture



Output: Torrent added to download list."### Async Subprocess Execution

```

All Deluge operations run asynchronously using Python's `asyncio` module:

## Architecture

```python

### Componentsasync def run_deluge_command(command: str) -> str:

    process = await asyncio.create_subprocess_shell(

1. **MCP Server (`main.py`)**:         f'deluge-console "{command}"',

   - Handles MCP protocol communication        stdout=asyncio.subprocess.PIPE,

   - Supports stdio and SSE transports        stderr=asyncio.subprocess.PIPE,

   - Registers and executes tools    )

   - Comprehensive logging for debugging    stdout, stderr = await process.communicate()

    # ...

2. **Deluge Integration**:```

   - Uses `deluge-console` command-line interface

   - Runs commands asynchronously via `asyncio.create_subprocess_exec`This ensures the MCP server remains responsive even during long-running operations.

   - Parses command output and returns structured data

   - Example commands:### Transport Mode

     - Get torrents: `deluge-console "info"`

     - Add magnet: `deluge-console "add <magnet_url>"`The server uses FastMCP's HTTP streamable transport:



3. **CLI (`cli.py`)**:```python

   - Built with Typer frameworkapp.run(transport="streamable-http")

   - Handles service installation with full venv setup```

   - Validates system requirements (root, Ubuntu, deluge-console)

   - Configures logging and service parametersThis allows AI assistants to connect to the server over HTTP and stream responses 

efficiently.

### Service Architecture

### Command Execution

**Production Service Setup:**

- **Location**: `/opt/deluge-mcp/`The server executes commands by invoking `deluge-console` as a subprocess:

- **Virtual Environment**: `/opt/deluge-mcp/venv/`

- **Logs**: `/var/log/deluge-mcp/`- **Get torrents**: `deluge-console "info"`

  - `deluge-mcp.log`: Standard output- **Add magnet**: `deluge-console "add <magnet_url>"`

  - `deluge-mcp-error.log`: Error output

- **Port**: 58880 (SSE transport)This approach ensures compatibility with existing Deluge installations and 

- **User**: rootdoesn't require direct API integration.

- **Transport**: SSE (Server-Sent Events)

## Development

**Why Root?**

### Project Structure

The service runs as root to:

- Ensure reliable access to Deluge daemon```

- Manage system-wide service dependenciesdeluge-mcp/

- Write to system log directories├── src/

- Survive system restarts with proper permissions│   └── deluge_mcp/

│       ├── main.py          # MCP server and tools

**Security Hardening:**│       └── cli.py           # CLI interface

├── pyproject.toml           # Dependencies and config

The systemd service includes:├── README.md               # This file

- `NoNewPrivileges=true`: Prevents privilege escalation└── LICENSE                 # License information

- `PrivateTmp=true`: Isolated /tmp directory```

- Automatic restart on failure

- Proper working directory isolation### Adding New Tools



### Async Command ExecutionTo add a new MCP tool, define an async function in `main.py` and decorate it 

with `@app.tool()`:

All Deluge operations run asynchronously using Python's `asyncio`:

```python

```python@app.tool()

async def run_deluge_command(command: str) -> dict[str, Any]:async def my_new_tool(param: str) -> str:

    process = await asyncio.create_subprocess_exec(    """

        "deluge-console",    Description of what the tool does.

        command,    

        stdout=asyncio.subprocess.PIPE,    Args:

        stderr=asyncio.subprocess.PIPE,        param: Description of the parameter

    )    

    stdout, stderr = await process.communicate()    Returns:

    # Process results...        Description of the return value

```    """

    output = await run_deluge_command(f"some-command {param}")

This ensures the MCP server remains responsive during long-running operations.    return output

```

## Troubleshooting

### Running Tests

### Service Not Starting

```bash

1. Check service status:poetry run pytest

```bash```

sudo systemctl status deluge-mcp

```## Security Considerations



2. View recent logs:- The daemon service runs with user-level permissions (not root)

```bash- `deluge-console` commands are executed through subprocess with proper escaping

# Check application logs- Magnet URLs are validated before processing

sudo tail -n 100 /var/log/deluge-mcp/deluge-mcp.log- Service installation requires sudo privileges only for systemd operations



# Check error logs## Troubleshooting

sudo tail -n 100 /var/log/deluge-mcp/deluge-mcp-error.log

### deluge-console not found

# Check systemd journal

sudo journalctl -u deluge-mcp -n 100Ensure Deluge is installed:

``````bash

sudo apt-get install deluge-console

3. Verify deluge-console is accessible:which deluge-console  # Should return a path

```bash```

which deluge-console

deluge-console info### Permission errors during daemon installation

```

The installation requires sudo access to create systemd service files. Make sure 

4. Test the service venv:your user has sudo privileges.

```bash

sudo /opt/deluge-mcp/venv/bin/python -c "import deluge_mcp; print('OK')"### Service fails to start

```

Check the service logs:

### Installation Issues```bash

sudo journalctl -u deluge-mcp -n 50

**"Must be run as root" error:**```

```bash

# Use sudoCommon issues:

sudo deluge-mcp install- Deluge daemon not running

```- Python environment not properly configured

- Port conflicts

**"deluge-console not found" error:**

```bash### Ubuntu check fails

# Install deluge

sudo apt-get updateThe daemon installation is designed for Ubuntu systems with systemd. If you're 

sudo apt-get install deluge-consoleon a different Linux distribution, you can use `--force` flag, but you may need 

to manually adapt the service configuration.

- Check your OS: `cat /etc/os-release`

See the [LICENSE](LICENSE) file for details.

### Permission Issues

## Authors

The service runs as root, but if you have permission issues:

- abi_jey (git@public.abja.dev)

```bash

# Verify service venv ownership## Links

sudo ls -la /opt/deluge-mcp/

- [Model Context Protocol](https://modelcontextprotocol.io/)

# Verify log directory ownership- [FastMCP](https://github.com/jlowin/fastmcp)

sudo ls -la /var/log/deluge-mcp/- [Deluge BitTorrent Client](https://deluge-torrent.org/)

- [Typer CLI Framework](https://typer.tiangolo.com/)

# Recreate if neededMCP server to automate deluge

sudo rm -rf /opt/deluge-mcp /var/log/deluge-mcp
sudo deluge-mcp install
```

### Connection Issues

Make sure Deluge daemon is running:
```bash
# Check if deluged is running
ps aux | grep deluged
sudo systemctl status deluged

# Start deluged if needed
sudo systemctl start deluged

# Enable auto-start
sudo systemctl enable deluged
```

### Port Conflicts

If port 58880 is already in use:

```bash
# Check what's using the port
sudo lsof -i :58880
sudo netstat -tulpn | grep 58880

# Edit service file to use different port
sudo nano /etc/systemd/system/deluge-mcp.service
# Change: --port 58880 to your desired port

# Reload and restart
sudo systemctl daemon-reload
sudo systemctl restart deluge-mcp
```

### Debug Logging

To enable DEBUG level logging:

1. Edit the source files to change logging level:
```python
# In main.py or cli.py
logging.basicConfig(level=logging.DEBUG, ...)
```

2. Reinstall the service:
```bash
sudo deluge-mcp uninstall
sudo deluge-mcp install
```

3. Or modify the systemd service temporarily:
```bash
sudo systemctl edit deluge-mcp
# Add: Environment="PYTHONUNBUFFERED=1"
sudo systemctl restart deluge-mcp
```

## Configuration

### Service Configuration

Key configuration values are defined in `cli.py`:
```python
SERVICE_PORT = 58880          # Default port for SSE transport
SERVICE_VENV_PATH = Path("/opt/deluge-mcp/venv")  # Service venv
SERVICE_LOG_PATH = Path("/var/log/deluge-mcp")     # Log directory
```

To change these, edit `src/deluge_mcp/cli.py` before installation.

### Deluge Configuration

The server uses default deluge-console behavior. Configure Deluge connection:

**System-wide (for root service):**
```bash
# Configuration file
/var/lib/deluged/.config/deluge/console.conf
```

**User-specific (for development):**
```bash
# Configuration file
~/.config/deluge/console.conf
```

### Transport Modes

**Stdio (Standard Input/Output):**
- Default mode
- Suitable for local testing
- Direct communication via stdin/stdout

**SSE (Server-Sent Events):**
- HTTP-based communication
- Runs on port 58880 by default
- Suitable for production deployment
- Allows remote MCP client connections

### Adding New Tools

To add a new MCP tool:

1. Add the tool to the `list_tools()` function:
```python
Tool(
    name="my_new_tool",
    description="Description of what the tool does",
    inputSchema={
        "type": "object",
        "properties": {
            "param": {
                "type": "string",
                "description": "Parameter description",
            }
        },
        "required": ["param"],
    },
)
```

2. Handle the tool in `call_tool()`:
```python
elif name == "my_new_tool":
    param = arguments.get("param", "")
    result = await run_deluge_command(f"some-command {param}")
    # Return TextContent with result
```

### Testing Locally

```bash
# Activate venv
source .venv/bin/activate

# Run in stdio mode for testing
python -m deluge_mcp.main

# Or run in SSE mode
python -m deluge_mcp.main --transport sse --port 58880

# Test with curl
curl http://localhost:58880/sse
```

## Uninstalling

To completely remove the service:

```bash
# Uninstall the service (requires sudo)
