Browserbase runs headless browsers in its own infrastructure, and this server hands one of those sessions to an agent. The tool surface is small on purpose: open or reuse a session, navigate, act, observe and extract — the page work is described in plain instructions and resolved by Stagehand rather than by CSS selectors written in advance. It needs a Browserbase API key and project id, plus a model key for the instruction layer. Note that the self-hosted repository was archived in July 2026 and the hosted endpoint at mcp.browserbase.com is now the maintained path.
