Browser Automation with agent-browser

Automates browser interactions for web testing, form filling, screenshots, and data extraction. 93% less context than Playwright MCP through Snapshot + Refs workflow.

Overview

• Web scraping and data extraction from dynamic/JS-rendered pages
• Form automation and multi-step workflows
• Screenshot capture and visual verification
• E2E test generation and debugging
• Content capture from authenticated pages
• Browser-based automation tasks via CLI

Quick Start

Copyagent-browser open <url>          # Navigate to page
agent-browser snapshot -i         # Get interactive elements with refs
agent-browser click @e1           # Click element by ref
agent-browser fill @e2 "text"     # Fill input by ref
agent-browser close               # Close browser

Core Workflow

1. Navigate: agent-browser open <url>
2. Snapshot: agent-browser snapshot -i (returns elements with refs like @e1, @e2)
3. Interact using refs from the snapshot
4. Re-snapshot after navigation or significant DOM changes
