mpai makes existing Claude Code and Codex sessions multiplayer over Tailscale, without shell access
Product Hunt·medium signal
Launched August 3 by Reagan Stock, mpai is an MIT-licensed terminal tool that lets teammates join an in-progress Claude Code or Codex session on a shared Mac network via Tailscale, seeing full prior-turn context and adding name-attributed prompts. The security model is deliberately narrow: the host Mac keeps execution authority, and the tool grants no arbitrary shell access or approval bypass. It hit #12 day rank with 93 upvotes and is free.
