Show HN: Local speech-to-text MCP server for Claude on Linux
github.comLink: https://github.com/marcindulak/stt-mcp-server-linux
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. FYI: discussed, and added to the curated list of Claude tools at https://github.com/hesreallyhim/awesome-claude-code/issues/1...
