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-profile

Output 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 URL

MCP Tools: Use kernel:list_browsers , kernel:get_browser .

Delete a Browser

kernel browsers delete <session_id> --yes

MCP 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.png

MCP 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
