A stealth-patched Chromium daemon that runs independently of your agent sessions and exposes browser control over HTTP and MCP. Navigate pages, take screenshots, evaluate JavaScript, and attach external CDP clients like Playwright or Puppeteer to the same running instance. Persistent sessions let you log in once and reuse cookies across multiple agent runs without re-authenticating. Non-persistent sessions expose a CDP URL so you can connect debuggers mid-flight. The MCP wrapper gives Claude and other clients tools for health checks, session creation, navigation, scripting, screenshot capture, and session purging. Useful when you need a shared browser that multiple agents can drive concurrently or when you want to inspect what an agent is actually seeing in the DOM without spinning up throwaway contexts.
