MCP.Pizza Chef: browserbase

A cloud browser does the visiting for you: your assistant opens a page, follows links, fills things in, and reads back whatever you asked for, all described in ordinary sentences rather than clicks. Browserbase runs a hosted version you can point at with a single line of settings; running your own copy needs a Browserbase account key and a Google Gemini key. The project itself is archived and no longer updated.

Browserbase MCP Server

Archived

This repository is archived and no longer maintained.

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:

mcp-server-browserbase FAQ

Is this still maintained?
No. The repository is archived and kept only as a reference. Browserbase points people to its hosted version instead.
Do I need an account?
Yes, a Browserbase account gives you the key it needs. The hosted version also covers the model costs for you.
Can I use this to gather prices from a shopping site?
Yes — you can ask it to open the page, find the items, and read the prices back to you.
How hard is setup?
The hosted version is a few lines pasted into your assistant's settings. Running it yourself means installing it or building a container first.
Does the browser run on my computer?
No, it runs in the cloud on Browserbase, so pages load away from your machine.
Which assistants work with it?
Any assistant that supports MCP connections. Ones that cannot reach a hosted address directly can use the small bridging command shown in the setup notes.
