Browser Use AgentCore Skill

Overview

This skill uses AWS Bedrock AgentCore Browser to perform automated web testing in the cloud. No local browser or display required – tests run on AWS infrastructure.

Features

• Test any URL with a real browser
• Capture full-page screenshots
• Check for JavaScript console errors
• Verify API health endpoints
• View live browser session in AWS Console

Prerequisites

1. AWS credentials configured
2. IAM permissions for AgentCore Browser
3. Python 3.10+

Required IAM Policy

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "bedrock-agentcore:StartBrowserSession",
        "bedrock-agentcore:StopBrowserSession",
        "bedrock-agentcore:GetBrowserSession"
      ],
      "Resource": "*"
    }
  ]
}

Quick Start

Install Dependencies

pip install bedrock-agentcore playwright boto3 nest-asyncio

Basic Usage

# Test a URL
python scripts/browser_test.py https://example.com

# Test with screenshot
python scripts/browser_test.py https://example.com --screenshot screenshot.png

# Test with API health check
python scripts/browser_test.py https://example.com --check-api

# Full test with JSON output
python scripts/browser_test.py https://example.com -s screenshot.png -a --json

Python API

Simple Test

from browser_test import test_url

# test_url is a synchronous function
results = test_url(
    url="https://example.com",
    screenshot_path="screenshot.png",
    check_api=True
)

print(f"Status: {results['status']}")
print(f"Title: {results['title']}")
print(f"Errors: {results['errors']}")

Advanced Usage with Playwright

from bedrock_agentcore.tools.browser_client import BrowserClient
from playwright.async_api import async_playwright

async def custom_test():
    client = BrowserClient(region="us-west-2")

    session = await client.start_browser_session(
        session_name="my-test",
        timeout=300,
        viewport={"width": 1920, "height": 1080}
    )

    ws_url, headers = await client.generate_ws_headers()

    async with async_playwright() as p:
        browser = await p.chromium.connect_over_cdp(ws_url, headers=headers)
        page = browser.contexts[0].pages[0]

        # Your custom test logic
        await page.goto("https://example.com")
        await page.click("button#submit")
        await page.wait_for_selector(".result")

        content = await page.content()
        await browser.close()

    await client.stop_browser_session()
    return content

Live View

While tests are running, you can watch the browser in real-time:

1. Open AWS Console – AgentCore Browser
2. Navigate to Built-in tools
3. Find your active session
4. Click View live session

Troubleshooting

Session Timeout

If tests timeout, increase the session timeout:

session = await client.start_browser_session(
    session_name="long-test",
    timeout=600  # 10 minutes
)

Permission Denied

Ensure your IAM role/user has the required permissions for AgentCore Browser.

Network Errors

Check that the target URL is accessible from AWS infrastructure. Internal/private URLs may not be reachable.
