See which coding agent awaits and respond from anywhere
Grounded in available product and source data
Muster is a Mac menu bar app for people running several AI coding agents at once. When a Claude Code, Codex or Cursor session needs input, an alert appears at the top of the screen with keys to allow it, deny it, see why the agent is asking, or pick an option.
Holding a modifier and pressing Tab lists every session, highlights the one waiting on you, and opens its window or terminal. It reads the session files agents already write and replies through their hooks on the local machine, so no account is needed and the data stays put.
