# Browserbase MCP Server [](https://smithery.ai/server/@browserbasehq/mcp-browserbase)  [The Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) 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](https://www.browserbase.com/) and [Stagehand](https://github.com/browserbase/stagehand). It enables LLMs to interact with web pages, take screenshots, extract information, and perform automated actions with atomic precision. ## What's New in Stagehand v3 Powered by [Stagehand v3.0](https://github.com/browserbase/stagehand), this MCP server now includes: - **20-40% Faster Performance**: Speed improvements across all core operations (`act`, `extract`, `observe`) through automatic caching - **Enhanced Extraction**: Targeted extraction and observation across iframes and shadow roots - **Improved Schemas**: Streamlined extract schemas for more intuitive data extraction - **Advanced Selector Support**: CSS selector support with improved element targeting - **Multi-Browser Support**: Compatible with Playwright, Puppeteer, and Patchright - **New Primitives**: Built-in `page`, `locator`, `frameLocator`, and `deepLocator` for simplified automation - **Experimental Features**: Enable cutting-edge capabilities with the `--experimental` flag For more details, visit the [Stagehand v3 documentation](https://docs.stagehand.dev/). ## Features | Feature | Description | | ------------------ | ----------------------------------------------------------- | | Browser Automation | Control and orchestrate cloud browsers via Browserbase | | Data Extraction | Extract structured data from any webpage | | Web Interaction | Navigate, click, and fill forms with ease | | Screenshots | Capture full-page and element screenshots | | Model Flexibility | Supports multiple models (OpenAI, Claude, Gemini, and more) | | Vision Support | Use annotated screenshots for complex DOMs | | Session Management | Create, manage, and close browser sessions | | High Performance | 20-40% faster operations with automatic caching (v3) | | Advanced Selectors | Enhanced CSS selector support for precise element targeting | ## How to Setup ### Quickstarts: #### Add to Cursor Copy and Paste this link in your Browser: ```text 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](https://smithery.ai/server/@browserbasehq/mcp-browserbase) 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](https://www.stagehand.dev/evals) in [Stagehand](https://www.stagehand.dev).  If your client supports SHTTP: ```json { "mcpServers": { "browserbase": { "type": "http", "url": "your-smithery-url.com" } } } ``` If your client doesn't support SHTTP: ```json { "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: ```json { "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: #### Option 1: Direct installation ```bash # Clone the Repo git clone https://github.com/browserbase/mcp-server-browserbase.git cd mcp-server-browserbase # Install the dependencies and bu
