Interesting, I have built https://github.com/michaellee8/voice-agent-devkit-mcp exactly for this, launch a chromium instance with virtual devices powered by Pulsewire and then hook it up with tts and stt so that playwright can finally have mouth and ears. Any chance we can talk?

That's actually interesting. Is it a dependancy on user to create the HTTP endpoints for the /speak and /transcript?

One of our learnings has been to allow plugging into existing frameworks easily. Example - livekit, pipecat etc.

Happy to talk if you can reach out to me on linkedin - https://www.linkedin.com/in/tarush-agarwal/
