Capture and automate macOS UI with the Peekaboo CLI.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Peekaboo Peekaboo is a full macOS UI automation CLI: capture/inspect screens, target UI elements, drive input, and manage apps/windows/menus. Commands share a snapshot cache and support `--json`/`-j` for scripting. Run `peekaboo` or `peekaboo <cmd> --help` for flags; `peekaboo --version` prints build metadata. Tip: run via `polter peekaboo` to ensure fresh builds. ## Features (all CLI capabilities, excluding agent/MCP) Core - `bridge`: inspect Peekaboo Bridge host connectivity - `capture`: live capture or video ingest + frame extraction - `clean`: prune snapshot cache and temp files - `config`: init/show/edit/validate, providers, models, credentials - `image`: capture screenshots (screen/window/menu bar regions) - `learn`: print the full agent guide + tool catalog - `list`: apps, windows, screens, menubar, permissions - `permissions`: check Screen Recording/Accessibility status - `run`: execute `.peekaboo.json` scripts - `sleep`: pause execution for a duration - `tools`: list available tools with filtering/display options Interaction - `click`: target by ID/query/coords with smart waits - `drag`: drag & drop across elements/coords/Dock …

How to install
mdr add z80dev/lemon/peekaboo@sha256:07a358d4fe82a729The line at the top of this page pins the label git:20260214.21456e2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
