Browserbase MCP Server

What is Browserbase MCP Server?

A Model Context Protocol server that provides cloud browser automation capabilities via Browserbase and Stagehand. It enables LLM applications—such as AI-powered IDEs and custom AI workflows—to control cloud browsers, interact with web pages, take screenshots, and execute JavaScript.

How to use Browserbase MCP Server?

The server offers two distinct MCPs: Browserbase MCP (located in browserbase/) for browser orchestration and data extraction, and Stagehand MCP (located in stagehand/) for high-level, atomic web instructions. Alternative installation is available through Smithery.

Key features of Browserbase MCP Server

• Orchestrate and control cloud browsers
• Extract structured data from any webpage

FAQ from Browserbase MCP Server

What is the difference between the Browserbase MCP and the Stagehand MCP?

The Browserbase MCP focuses on core browser automation (navigation, screenshots, data extraction, console monitoring). The Stagehand MCP provides higher-level atomic instructions (e.g., act("click the login button")) and supports multiple LLM models with vision capabilities.

What do I need to start using this server?

You need a Browserbase account and API keys to provision cloud browsers. Detailed setup guides are available in the browserbase/ and stagehand/ directories.

Can I run this server locally without cloud infrastructure?

No. This server is designed for a cloud browser environment using Browserbase; it does not support local browser instances.

How does this server compare to the Playwright MCP Server?

The Browserbase MCP Server builds on Playwright but adds cloud browser orchestration and high-level Stagehand instructions. It credits and thanks the Playwright team for their foundational work.

Is this project open source?

Yes. The Stagehand MCP component is explicitly listed as open source, and community contributions are welcomed via the Stagehand Slack community.
