[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/).

## 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
