kernel

browser infrastructure for AI agents and web automations. cloud browsers in <30ms, anti-bot stealth mode, managed auth, playwright execution, and a serverless app platform — no local chrome needed.

trusted by 3,000+ teams.

what's included

mcp server

connects cursor to kernel's cloud browser platform. browsers spin up in the cloud in <30ms — no local chrome needed.

available tools:

• create_browser — launch cloud browsers with stealth mode, proxies, custom viewports, and profiles
• execute_playwright_code — run playwright/typescript against any browser session
• take_screenshot — capture browser screenshots
• setup_profile — save and reuse browser sessions with persistent cookies and logins
• search_docs — search kernel documentation

skills

• browser-automation — patterns for building browser automations with the kernel sdk and playwright
• kernel-mcp — guide for using kernel's mcp tools effectively
• web-scraping — scraping patterns with stealth mode and proxies
• kernel-typescript-sdk — typescript sdk patterns: playwright, CDP connections, stagehand integration, deployable apps
• kernel-python-sdk — python sdk patterns: playwright, browser-use integration, async context managers, deployable apps
• managed-auth — authenticate AI agents across websites with persistent login sessions

rules

• kernel-best-practices — always clean up browsers, use stealth for bot detection, handle errors

setup

1. install from the cursor marketplace
2. authenticate with your kernel account (oauth — opens in browser)
3. start using kernel tools in cursor agent mode

no api key needed for setup — oauth handles auth automatically. for CI/CD or headless environments, use an api key:

{
  "mcpServers": {
    "kernel": {
      "url": "https://mcp.onkernel.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_KERNEL_API_KEY"
      }
    }
  }
}

get started

• sign up at kernel.sh
• read the docs
• check out the typescript sdk and python sdk
• open source browser image: kernel-images
