- **DCIM** - Sites, Locations, Racks, Devices, Interfaces, Cables, Power
- **IPAM** - IP Addresses, Prefixes, VLANs, VRFs, ASNs, Services
- **Circuits** - Providers, Circuits, Terminations
- **Virtualization** - Clusters, Virtual Machines, VM Interfaces
- **Tenancy** - Tenants, Contacts, Contact Assignments
- **VPN** - Tunnels, IKE/IPSec Policies, L2VPN
- **Wireless** - Wireless LANs, Links, Groups
- **Extras** - Tags, Custom Fields, Webhooks, Config Contexts, Audit Log

## Installation

### 1. Clone and Setup

```bash
cd /path/to/mcp-servers/netbox
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
pip install -r requirements.txt
```

### 2. Configure Credentials

Create the system-level configuration file:

```bash
mkdir -p ~/.config/claude
cat > ~/.config/claude/netbox.env << 'EOF'
NETBOX_API_URL=https://your-netbox-instance/api
NETBOX_API_TOKEN=your-api-token-here
NETBOX_VERIFY_SSL=true
NETBOX_TIMEOUT=30
EOF
```

**Getting a NetBox API Token:**
1. Log into your NetBox instance
2. Navigate to your profile (top-right menu)
3. Go to "API Tokens"
4. Click "Add a token"
5. Copy the generated token

### 3. Register with Claude Code

Add to your Claude Code MCP configuration (`~/.config/claude/mcp.json` or project `.mcp.json`):

```json
{
  "mcpServers": {
    "netbox": {
      "command": "/path/to/mcp-servers/netbox/.venv/bin/python",
      "args": ["-m", "mcp_server.server"],
      "cwd": "/path/to/mcp-servers/netbox"
    }
  }
}
```

## API Coverage

This MCP server provides comprehensive coverage of the NetBox REST API v4.x:

- Full CRUD operations for all major models
- Filtering and search capabilities
- Special endpoints (available prefixes, available IPs)
- Pagination handling (automatic)
- Error handling with detailed messages

## Error Handling

The server returns detailed error messages from the NetBox API, including:
- Validation errors
- Authentication failures
- Not found errors
- Permission errors

## Security Notes

- API tokens should be kept secure and not committed to version control
- Use environment variables or the system config file for credentials
- SSL verification is enabled by default
- Consider using read-only tokens for query-only workflows

## Troubleshooting

### Common Issues

1. **Connection refused**: Check `NETBOX_API_URL` is correct and accessible
2. **401 Unauthorized**: Verify your API token is valid
3. **SSL errors**: Set `NETBOX_VERIFY_SSL=false` for self-signed certs (not recommended for production)
4. **Timeout errors**: Increase `NETBOX_TIMEOUT` for slow connections

### Debug Mode

Enable debug logging:

```python
import logging
logging.basicConfig(level=logging.DEBUG)
```

## Contributing

1. Follow the existing code patterns
2. Add tests for new functionality
3. Update documentation for new tools
4. Ensure compatibility with NetBox 4.x API
