Browserbase MCP: Documentation

Updated:

Connection

  • Hosted (recommended): https://mcp.browserbase.com/mcp (stdio/Streamable HTTP) — "the easiest way to get started," per the Browserbase team.
  • Local: npx @browserbasehq/mcp with BROWSERBASE_API_KEY, BROWSERBASE_PROJECT_ID and GEMINI_API_KEY (the default model for reading page actions; swappable for another).

Tools (6)

  • start — create a new cloud browser session or reuse the current one.
  • navigate — go to a given URL.
  • act — perform a page action from a natural-language description (click, type, etc.).
  • observe — identify actionable elements on the page.
  • extract — pull structured data from the page.
  • end — close the current session.

Agent flow

"Open site X, find the signup form and fill it with test data", "extract the pricing table from the page", "log in and show the list of recent orders" — no CSS selectors, just a description of the action.

Note

The browserbase/mcp-server-browserbase repository was archived on July 20, 2026 — "read-only" and no longer maintained as a reference implementation. The hosted mcp.browserbase.com/mcp endpoint keeps running and remains the recommended way to connect; the README separately warns that the archived self-hosted version doesn't reflect Browserbase's current production service.

Pricing

Browserbase itself is a paid service (cloud browser sessions are billed by time/usage); the MCP server is free and open source (3.4k★), but requires an active Browserbase account and a model key for act/extract.
