# MouseHerdr > MouseHerdr is a free, open-source (MIT) macOS menu bar app that puts your Herdr AI coding agents one thumb-tap away: tap the Logitech MX Master 4 thumb pad for an agent wheel, then answer, approve or jump to any agent. It also remaps the buttons and drags and snaps windows, over Bluetooth, without Logi Options+. A one-page overview of MouseHerdr, the Herdr AI coding agent wheel for macOS and the MX Master 4, written from its public GitHub repository (royosherove/mouse-herdr) and the author’s own copy: what it does, who it is for, requirements and limitations, download and build-from-source steps, permissions, how it talks to Herdr and how it works internally, privacy and an FAQ. Downloads and source live on GitHub; this site hosts no binaries. MouseHerdr is an independent fan project: Roy Osherove is not affiliated with Herdr or Logitech, and built it for his own workflow.
