Browserbase provides cloud browser automation infrastructure powered by Stagehand, enabling AI assistants to control managed browsers for web interaction tasks. The service hosts browser instances that can navigate websites, extract structured data, capture screenshots, and perform automated actions with AI-guided precision. Key capabilities include: - Cloud-hosted browser automation supporting Playwright, Puppeteer, and Patchright - AI-powered web interaction for navigation, form filling, clicking, and scrolling - Structured data extraction from web pages including iframes and shadow roots - Full-page and element-level screenshot capture with DOM annotation - Session management for creating and closing isolated browser instances - Support for multiple AI models (OpenAI, Claude, Gemini, and others) - Enhanced CSS selector support with improved element targeting accuracy - 20-40% faster operations through automatic caching (Stagehand v3)

Browserbase MCP Server

[](https://smithery.ai/server/@browserbasehq/mcp-browserbase)

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, take screenshots, extract information, and perform automated actions with atomic precision.

cursor://anysphere.cursor-deeplink/mcp/install?name=browserbase&config=eyJjb21tYW5kIjoibnB4IEBicm93c2VyYmFzZWhxL21jcCIsImVudiI6eyJCUk9XU0VSQkFTRV9BUElfS0VZIjoiIiwiQlJPV1NFUkJBU0VfUFJPSkVDVF9JRCI6IiIsIkdFTUlOSV9BUElfS0VZIjoiIn19

We currently support 2 transports for our MCP server, STDIO and SHTTP. We recommend you use SHTTP with our remote hosted url to take advantage of the server at full capacity.

SHTTP:

To use the Browserbase MCP Server through our remote hosted URL, add the following to your configuration.

Go to smithery.ai and enter your API keys and configuration to get a remote hosted URL. When using our remote hosted server, we provide the LLM costs for Gemini, the best performing model in Stagehand.

If your client supports SHTTP:

{
  "mcpServers": {
    "browserbase": {
      "type": "http",
      "url": "your-smithery-url.com"
    }
  }
}

If your client doesn't support SHTTP:

{
  "mcpServers": {
    "browserbase": {
      "command": "npx",
      "args": ["mcp-remote", "your-smithery-url.com"]
    }
  }
}

STDIO:

You can either use our Server hosted on NPM or run it completely locally by cloning this repo.

> ❗️ Important: If you want to use a different model you have to add --modelName to the args and provide that respective key as an arg. More info below.

To run on NPM (Recommended)

Go into your MCP Config JSON and add the Browserbase Server:

{
  "mcpServers": {
    "browserbase": {
      "command": "npx",
      "args": ["@browserbasehq/mcp-server-browserbase"],
      "env": {
        "BROWSERBASE_API_KEY": "",
        "BROWSERBASE_PROJECT_ID": "",
        "GEMINI_API_KEY": ""
      }
    }
  }
}

That's it! Reload your MCP client and Claude will be able to use Browserbase.

To run 100% local:
