It was originally published as a reference implementation and is retained for historical purposes. It should not be interpreted as representative of Browserbase's current production services or implementation.
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.**
Tools
This server exposes 6 tools that match the hosted Browserbase MCP server:
| Tool | Description | Input |
| ---------- | --------------------------------------- | -------------------------- |
| start | Create or reuse a Browserbase session | _(none)_ |
| end | Close the current Browserbase session | _(none)_ |
| navigate | Navigate to a URL | { url: string } |
| act | Perform an action on the page | { action: string } |
| observe | Observe actionable elements on the page | { instruction: string } |
| extract | Extract data from the page | { instruction?: string } |
How to Setup
We currently support 2 transports for our MCP server, STDIO and SHTTP. We recommend you use SHTTP with our hosted MCP server to take advantage of the server at full capacity.
SHTTP (Hosted MCP):
Use the Browserbase hosted MCP server at https://mcp.browserbase.com/mcp. This is the easiest way to get started -- we host the server and provide the LLM costs for Gemini, the best performing model in Stagehand.
For full setup instructions, see the Browserbase MCP documentation.
If your client supports SHTTP:
If your client doesn't support SHTTP:
STDIO (Self-Hosted):
You can either use our server hosted on NPM or run it completely locally by cloning this repo.
> **Note:** 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 via NPM (Recommended)
Go into your MCP Config JSON and add the Browserbase Server:
That's it! Reload your MCP client and you're ready to go.
To run 100% local:
Option 1: Direct installation
Option 2: Docker
Then in your MCP Config JSON run the server:
Using Direct Installation
Using Docker
