Implementation Reference

• src/sysinfo/server.py:133-149 (handler)

  The primary tool handler for 'get_connected_devices'. Decorated with @mcp.tool for registration. Fetches device info via get_connectivity_devices() helper, formats with timestamp/header, and returns as ToolResult text content.
  @mcp.tool def get_connected_devices() -> ToolResult: """Get USB and Bluetooth device information. Lists all connected USB devices and paired/active Bluetooth devices. Useful for peripheral troubleshooting and device inventory. """ info_sections = [] info_sections.append("# Connected Devices") info_sections.append(f"*Generated: {datetime.now().strftime('%Y-%m-%d %H:%M:%S')}*\n") try: info_sections.extend(get_connectivity_devices()) except Exception as e: info_sections.append(f"⚠️ **Device detection error**: {str(e)}") return text_response("\n".join(info_sections))
• src/sysinfo/collectors.py:798-814 (helper)

  Core helper function implementing the device collection logic. Combines USB devices (via get_usb_devices()) and Bluetooth devices (via get_bluetooth_devices()), formats as markdown list.
  def get_connectivity_devices() -> List[str]: """Get USB and Bluetooth device information""" info = [] info.append("## 🔌 Connected Devices") # USB devices usb_info = get_usb_devices() if len(usb_info) > 1: # More than just the header info.extend(usb_info) # Bluetooth devices bt_info = get_bluetooth_devices() if len(bt_info) > 1: # More than just the header info.append("") # Add spacing info.extend(bt_info) return info
