This connects Claude to Browserbase's cloud browser automation infrastructure through six core tools: start and end sessions, navigate to URLs, act on page elements, observe actionable content, and extract data based on instructions. Under the hood it uses Stagehand for the AI-powered browser control, defaulting to Gemini 2.5 Flash Lite but supporting other models like GPT-4o or Claude if you bring your own API key. Browserbase hosts a version at mcp.browserbase.com that handles the LLM costs, or you can self-host via npx or Docker with flags for proxies, verified identity, custom contexts, and viewport sizing. Reach for this when you need Claude to scrape dynamic sites, fill forms, or interact with web apps that require actual browser execution rather than static HTML parsing.
