Headless browser automation CLI optimized for AI agents: drives a real browser via accessibility-tree snapshots and @e1-style refs for ~93% less context than raw DOM tools. Use whenever a task needs to interact with a live web page: click, fill forms, log in, extract text or data, take screenshots, test a running web app, or scrape a site. Triggers on 'automate the browser', 'fill this form', 'click the button', 'take a screenshot of the page', 'log into', 'scrape this site', 'test my web…
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
# agent-browser ## Overview **agent-browser** is an open-source browser automation CLI from Vercel Labs, built for LLM interaction with a **snapshot + refs** system: instead of a full DOM, `snapshot` returns an accessibility tree of just the interactive elements (buttons, inputs, links) with semantic labels, each tagged with a stable `@e1`-style ref. Full DOM dumps run 5000+ nodes / 200KB of context; an accessibility-tree snapshot is 50-100 elements / ~10KB, roughly a 93% reduction. Refs also survive re-renders, so they don't need re-deriving after every DOM tweak the way CSS selectors do. See [When to Use vs Playwright](#when-to-use-vs-playwright) for when this CLI beats DOM-based tools. ### Installation ```bash # macOS (preferred — managed by Homebrew) brew install agent-browser # Linux / fallback npm install -g agent-browser # Install browser binaries after either method agent-browser install # Linux: also install system dependencies agent-browser install --with-deps # Verify health agent-browser doctor ``` ## Quick Start ### Basic Workflow ```bash # 1. Navigate to a page agent-browser open https://example.com # 2. Get snapshot with refs agent-browser snapshot -i …

How to install
mdr add mgiovani/cc-arsenal/agent-browser@sha256:e994423acf7aa52eThe line at the top of this page pins the label git:20261005.b620662, 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.
