Stagehand Browser Automation Plugin

Browser automation skill for Claude Code using Stagehand. This plugin enables Claude to automate web browser interactions, extract data, and navigate websites using natural language.

Installation

Install the plugin from the Claude Code marketplace:

/plugin install stagehand@claude-plugin-directory

Prerequisites

This plugin requires the browser automation CLI tools to be installed separately. The CLI tools are available from the GitHub marketplace.

Step 1: Add the GitHub Marketplace

/plugin marketplace add browserbase/agent-browse

Step 2: Install the Browser Automation CLI Plugin

/plugin install browser-automation@browser-tools

Step 3: Set Up the CLI Tools

After installing the browser-automation plugin, you need to set up the CLI tools:

  1. Navigate to the plugin directory (typically ~/.claude/plugins/browser-automation/)
  2. Install dependencies and build: 
    npm install
  3. Link the browser command globally: 
    npm link
  4. Configure your Anthropic API key: 
    export ANTHROPIC_API_KEY="your-api-key-here"
    Or use Claude Code's subscription token (recommended if you have Claude Pro/Max): 
    claude setup-token

Step 4: Verify Installation

Test that the browser command is available:

browser navigate https://example.com

Usage

Once installed and configured, you can use natural language to automate browser tasks:

  • "Go to Hacker News, get the top post comments, and summarize them"
  • "QA test http://localhost:3000 and fix any bugs you encounter"
  • "Extract product information from example.com/products"

Claude will automatically use the browser automation skill when you ask for web-related tasks.

Features

  • Natural Language Control: Describe browser actions in plain English
  • Data Extraction: Extract structured data from web pages
  • Screenshot Capture: Take screenshots for visual verification
  • Persistent Sessions: Browser state persists between commands
  • Chrome Profile Integration: Uses your Chrome profile for cookies and sessions

Troubleshooting

Chrome not found

Install Chrome for your platform:

Browser command not found

Make sure you've run npm link in the browser-automation plugin directory after installing it.

API Key Issues

  • If you have Claude Pro/Max, use claude setup-token (recommended)
  • Otherwise, export ANTHROPIC_API_KEY in your terminal
  • Or create a .env file in the plugin directory with your API key
