Muster 1.0
Every agent, one glance. A native Mac menu bar app for your Claude, Codex and Cursor sessions.
- See who needs you. A glass alert at the top of the screen the moment an agent waits on you, plus a count in the menu bar.
- Answer from anywhere. Allow a command, pick an answer or approve a plan with ⌥↩, from the alert, the switcher or the notification.
- ⌥Tab to any agent. Most urgent first. Let go or click to land in its window, or the terminal it runs in.
- Find anything. ⌃⌥Space searches every session.
- Know what it costs. Tokens and API-rate cost per session, priced per model and per message.
- A tour you do, not read. The first run finds your agents and has you try the switcher for real.
Install: open Muster.dmg and drag Muster to Applications, or brew install --cask josefchen/tap/muster. Signed and notarized. macOS 14 or later, Apple silicon or Intel.
