Bridges Claude Desktop to your Google Home and Alexa devices so you can control smart speakers through conversation. You get natural language commands for playback control, volume adjustments, and device management without switching to the Google Home or Alexa apps. Useful when you're already working in Claude and want to queue up music, pause what's playing, or adjust speaker settings without context switching. The stdio transport keeps it local to your machine. Note that the source repository doesn't detail specific API methods, so you'll want to check the docs for authentication setup and supported speaker capabilities before installing.
