AI-optimized browser automation CLI with context-efficient snapshots. Use for long autonomous sessions, self-verifying workflows, video recording, and cloud browser testing (Browserbase). Use when: Invoke to drive a real browser for navigation, screenshots, or DOM actions.
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 Skill Browser automation CLI designed for AI agents. Uses "snapshot + refs" paradigm for 93% less context than Playwright MCP. ## Quick Start ```bash # Install globally npm install -g agent-browser # Download Chromium (one-time) agent-browser install # Linux: include system deps agent-browser install --with-deps # Verify agent-browser --version ``` ## Core Workflow The 4-step pattern for all browser automation: ```bash # 1. Navigate agent-browser open https://example.com # 2. Snapshot (get interactive elements with refs) agent-browser snapshot -i # Output: button "Sign In" @e1, textbox "Email" @e2, ... # 3. Interact using refs agent-browser fill @e2 "user@example.com" agent-browser click @e1 # 4. Re-snapshot after page changes agent-browser snapshot -i ``` ## When to Use (vs chrome-devtools) | Use agent-browser | Use chrome-devtools | |-------------------|---------------------| | Long autonomous AI sessions | Quick one-off screenshots | | Context-constrained workflows | Custom Puppeteer scripts needed | | Video recording for debugging | WebSocket full frame debugging | | Cloud browsers (Browserbase) | Existing workflow integration | …

How to install
mdr add haposoft/cafekit/cf-agent-browser@sha256:99961b90c28e5236The line at the top of this page pins the label v1.0.0, 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.
