Live Translate MCP server

This is a small helper that lets Claude listen to an audio file, translate it between English and Mandarin, and speak the translation back. It is handy if you deal with voice notes, meetings, or interviews in either language and want a quick translation without uploading your audio anywhere. The listening and the speaking happen on your own machine; only the text of the translation goes to Claude.

What this MCP server does

You give your AI the location of a WAV audio file, or ask it to check that everything is ready. The AI passes that request to this helper. The helper listens to the audio on your computer, turns the speech into text, sends only that text to Claude for translation, then creates a spoken version of the translation on your computer and plays it. You get the original words, the translation, and a new audio file saved next to the original.
