- **System Monitoring** - Check system health, pool status, and resource usage

### TrueNAS SCALE Features (24.04+)
*Automatically enabled when connected to SCALE*
- **Apps** - Manage Docker Compose-based TrueNAS applications
- **Incus Instances** - Control Incus VMs and containers (SCALE 25.04+)
- **Legacy VMs** - Manage bhyve virtual machines

### Enterprise Features
- **Type-Safe Operations** - Full Pydantic models for request/response validation
- **Comprehensive Error Handling** - Detailed error messages and recovery guidance
- **Production Logging** - Structured logging with configurable levels
- **Connection Pooling** - Efficient HTTP connection management with retry logic
- **Rate Limiting** - Built-in rate limiting to prevent API abuse
- **Environment-Based Config** - Flexible configuration via environment variables

## 📦 Installation

### Quick Start with uvx (Recommended)

The easiest way to run TrueNAS MCP Server is with [uvx](https://github.com/astral-sh/uv):

```bash
# Run directly without installation
uvx truenas-mcp-server

# Or install globally with uv
uv tool install truenas-mcp-server
```

### Traditional Installation

```bash
# With pip
pip install truenas-mcp-server

# Or with pipx for isolated environment
pipx install truenas-mcp-server
```

### From Source

```bash
git clone https://github.com/vespo92/TrueNasCoreMCP.git
cd TrueNasCoreMCP
pip install -e .
```

## 🔧 Configuration

### Environment Variables

Create a `.env` file or set environment variables:

```bash
# Required
TRUENAS_URL=https://your-truenas-server.local
TRUENAS_API_KEY=your-api-key-here

# Optional
TRUENAS_VERIFY_SSL=true                    # Verify SSL certificates
TRUENAS_LOG_LEVEL=INFO                     # Logging level
TRUENAS_ENV=production                     # Environment (development/staging/production)
TRUENAS_HTTP_TIMEOUT=30                    # HTTP timeout in seconds
TRUENAS_ENABLE_DESTRUCTIVE_OPS=false      # Enable delete operations
TRUENAS_ENABLE_DEBUG_TOOLS=false          # Enable debug tools
```

### Getting Your API Key

1. Log into TrueNAS Web UI
2. Go to **Settings → API Keys**
3. Click **Add** and create a new API key
4. Copy the key immediately (it won't be shown again)

### Claude Desktop Configuration

**Add to your Claude Desktop config** (`claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "truenas": {
      "command": "uvx",
      "args": ["truenas-mcp-server"],
      "env": {
        "TRUENAS_URL": "https://your-truenas-server.local",
        "TRUENAS_API_KEY": "your-api-key-here",
        "TRUENAS_VERIFY_SSL": "false"
      }
    }
  }
}
```

**Note**: This uses `uvx` to automatically manage the Python environment. Make sure you have [uv](https://github.com/astral-sh/uv) installed:
```bash
# Install uv if you haven't already
curl -LsSf https://astral.sh/uv/install.sh | sh
# or
brew install uv
```

## 📚 Usage Examples

### With Claude Desktop

Once configured, you can interact with TrueNAS using natural language:

```
"List all storage pools and their health status"
"Create a new dataset called 'backups' in the tank pool with compression"
"Set up an SMB share for the documents dataset"
"Create a snapshot of all datasets in the tank pool"
"Show me users who have sudo privileges"

# TrueNAS SCALE virtualization examples
"List all running apps and their status"
"Get the configuration for the sonarr app"
"Show me all Incus VMs and containers"
"Update the crypto-nodes VM to use 8 CPUs"
"Restart the plex app"
```

### As a Python Library

```python
from truenas_mcp_server import TrueNASMCPServer

# Create server instance
server = TrueNASMCPServer()

# Run the server
server.run()
```

### Programmatic Usage

```python
import asyncio
from truenas_mcp_server.client import TrueNASClient
from truenas_mcp_server.config import Settings

async def main():
    # Initialize client
    settings = Settings(
        truenas_url="https://truenas.local",
        truenas_api_key="your-api-key"
    )
    
    async with TrueNASClient(settings) as client:
        # List pools
        pools = await client.get("/pool")
        print(f"Found {len(pools)} pools")
        
        # Create a dataset
        dataset = await client.post("/pool/dataset", {
            "name": "tank/mydata",
            "compression": "lz4"
        })
        print(f"Created dataset: {dataset['name']}")

asyncio.run(main())
```

## 📄 Pagination and Response Control

All list operations support pagination to reduce token usage when working with LLM clients. Get operations support optional raw API response inclusion for debugging.

### Pagination Parameters

All `list_*` tools support these parameters:

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `limit` | integer | 100 | Maximum items to return (max: 500) |
| `offset` | integer | 0 | Number of items to skip |

**Response format:**
```json
{
  "success": true,
  "items": [...],
  "metadata": { ... },
  "pagination": {
    "total": 250,
    "limit": 100,
    "offset": 0,
    "returned": 100,
    "has_more": true
  }
}
```

**Usage examples:**
```
"List the first 10 datasets"          → limit=10
"Show users 50-100"                   → limit=50, offset=50
"Get all SMB shares (up to 500)"      → limit=500
```

### Include Raw API Response

Get operations for apps, instances, and VMs support the `include_raw` parameter:

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `include_raw` | boolean | false | Include full API response for debugging |

**When to use `include_raw=true`:**
- Debugging API response structure
- Accessing fields not included in the formatted response
- Troubleshooting integration issues

**Tools supporting `include_raw`:**
- `get_app` - App details
- `get_instance` - Incus instance details
- `get_legacy_vm` - Legacy VM details

### Dataset Response Control

The `list_datasets` and `get_dataset` tools support an additional parameter:

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `include_children` | boolean | true | Include child datasets (can reduce payload significantly) |

**Usage:**
```
"List only top-level datasets"        → include_children=false
"Get tank dataset without children"   → include_children=false
```
