Best for
  • Web developers debugging and testing complex web applications
  • QA engineers automating end-to-end testing
  • AI agents needing selector-free browser interaction
  • Developers who want AI clients to directly control the browser
  • Scenarios requiring DOM-level understanding and low-latency automation (50-200 ms)
  • Multi-client support (Claude Code, Cursor, VS Code, etc.)
  • Internal tools or automation scripts needing browser interaction
Not for
  • Tasks requiring high-precision visual verification (e.g., image recognition)
  • Bypassing browser security restrictions
  • Deployment in environments without Node.js 20+
  • Headless browser or server-side monitoring
  • Bypassing website restrictions or unsupervised automation
  • Automation on sensitive pages without human supervision
  • Complex scenarios that require visual understanding (e.g., screenshots)
Required permissions
  • Requires Node.js runtime
  • Requires network access to navigate web pages
  • May require access to local development servers
  • Requires ability to execute JavaScript code
  • Requires installing the Chrome extension, which requests permissions for active tab, debugger, storage, etc.
  • MCP server needs to connect to the extension via WebSocket (default ws://localhost:7225)
  • Optional Streamable HTTP mode requires allowing connections to http://127.0.0.1:7226/mcp
  • Uploading files requires providing absolute local paths
Risks and side effects
  • May execute unverified navigation or actions, leading to unexpected behavior
  • May expose sensitive information (e.g., console logs)
  • Depends on a third-party service (kogiQA)
  • Potential security risks if browser automation is misused
  • Browser automation can be unpredictable on complex or sensitive sites; supervision is required
  • Credentials and payment info are stored in a vault but require user unlock flows
  • API keys are encrypted in Chrome storage, but clients may send page context to model providers
  • MCP server is a local process, posing local security risks
  • Capability catalog allows most non-denied origins but is gated by multiple checks
