Mcp Server Browserbase
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.

The Model Context Protocol (MCP) is an open protocol that enables seamless integration between LLM applications and external data sources and tools. Whether you're building an AI-powered IDE, enhancing a chat interface, or creating custom AI workflows, MCP provides a standardized way to connect LLMs with the context they need.
This server provides cloud browser automation capabilities using Browserbase and Stagehand. It enables LLMs to interact with web pages, extract information, and perform automated actions.
This is a self-hostable version of the Browserbase hosted MCP server with the same tools and functionality. We recommend using the hosted version for the easiest setup.
