A push-to-talk speech transcription setup for Linux, using a 500-line Python MCP server. Runs locally in Docker, no external API calls. Press Right Ctrl to record audio; Whisper transcribes it, and the transcript is sent into Claude running in a Tmux session.

I'm a Linux user and wanted to have a speech-to-text functionality in Claude, so I can talk to it, like Armin Ronacher https://www.youtube.com/watch?v=bpWPEhO7RqE#t=5m37s demonstrates on macOS. I was not able to find a small codebase doing this, that I can understand.

The project I'm submitting is about 500 lines of Python, and is packaged as Docker, so facilitate the setup. When creating the project I added some security measures, like running the Docker container as non-root, and performing Whisper output sanitization before passing it to Claude.

Thes setup is Linux-only due to `/dev` device dependencies.
