How do I see what the browser is doing?

You can use the 'screenshot' command to see the current state, or run the CLI with the '--headed' flag to open a visible browser window for debugging.

Does it support parallel browsing?

Yes, it supports independent browser sessions using the --session flag, allowing you to automate multiple websites simultaneously without state interference.

Can I use it to scrape data behind a login?

Absolutely. You can script the login sequence using 'fill' and 'click' commands, then use 'snapshot' or 'get' commands to extract data from protected pages.

Is this different from the Playwright MCP?

Yes. While Playwright MCP uses direct tool integrations, agent-browser uses a Bash-based CLI interface, which is often faster for one-off automation tasks and simpler to debug via terminal output.

How does ref-based selection work?

The skill generates accessibility snapshots that assign temporary IDs (like @e1) to interactive elements, allowing Claude to click or fill them precisely without needing complex CSS selectors or XPaths.

Browser Automation

Automates headless browser interactions and web data extraction using a ref-based CLI optimized for AI agents.

Agent Browser Automation provides a specialized CLI interface for Claude to interact with web pages using Vercel's agent-browser tool. Unlike traditional automation frameworks, it utilizes a unique ref-based selection system (@e1, @e2) derived from accessibility snapshots, making it significantly more accurate for LLMs to identify and interact with DOM elements. It supports comprehensive navigation, complex form filling, high-resolution screenshot capture, and structured data scraping across parallel sessions, serving as a robust alternative to Playwright for rapid, bash-driven web workflows.
