    }
  }
}
```

## Available Tools

- `calculate`: Perform math operations (add, subtract, multiply, divide)
- `get_time`: Get current time
- `echo`: Echo back messages

## Available Resources

- `config://server`: Get server configuration
- `data://sample/{item_id}`: Get sample data by ID (1, 2, or 3)
- `image://sample/chart`: PNG image of a sine wave chart
- `csv://sample/data`: Sample sales data in CSV format

Note: Resources are defined but may have issues with FastMCP v2.8.0. The image resource returns bytes and CSV returns text with proper MIME types set.
