Browser Management
Create and manage sandboxed Chrome browser instances in the cloud.
When to Use This Skill
Use browser-management skill when you need to:
- Create browser sessions - Launch new Chrome browser instances with custom configurations (stealth mode, headless, profiles, proxies)
- List and monitor browsers - View all active browser sessions and their details
- Get live view URLs - Access remote browser sessions for monitoring and control
- Execute automation - Run Playwright/TypeScript code against browser sessions
- Capture screenshots - Take screenshots of browser pages or specific regions
- Manage browser lifecycle - Delete browser sessions when done to free resources
- Work with browser profiles - Load saved authentication data and cookies into sessions
Prerequisites
Load the kernel-cli skill for Kernel CLI installation and authentication.
Create a Browser
# Basic browser creation
kernel browsers create
# With options
kernel browsers create --stealth --headless -o json
kernel browsers create --profile-name my-profileOutput contains session_id, cdp_ws_url, and browser_live_view_url.
MCP Tool: Use kernel:create_browser with parameters like headless, stealth, or profile_name.
List and Get Browsers
Unless otherwise noted, id arguments refer to the browser session ID, not invocation IDs returned by Kernel commands.
kernel browsers list -o json
kernel browsers get <session_id> -o json
kernel browsers view <session_id> -o json # Get live view URLMCP Tools: Use kernel:list_browsers, kernel:get_browser.
Delete a Browser
kernel browsers delete <session_id> --yesMCP Tool: Use kernel:delete_browser with the session_id.
Browser Automation
Execute Playwright Code
Run Playwright/TypeScript code against a browser session:
kernel browsers playwright execute <session_id> 'await page.goto("https://example.com")'MCP Tool: Use kernel:execute_playwright_code to run automation scripts. If no session_id is provided, a new browser is created and cleaned up automatically.
Take Screenshots
Capture screenshots of browser pages:
kernel browsers computer screenshot <session_id> --to screenshot.pngMCP Tool: Use kernel:take_screenshot with session_id. Optionally specify region with x, y, width, height.
Common Pattern: Create, Use, Delete
# Create browser and capture session_id
SESSION=$(kernel browsers create -o json | jq -r '.session_id')
# Use the browser...
# [perform operations]
# Cleanup
kernel browsers delete $SESSION --yes
