Browserbase MCP
DegradedBrowserbase MCP is a server for driving Browserbase's cloud browser on the Stagehand engine: the agent opens pages, performs actions in natural language (act), and extracts data (extract) with no selectors. Six tools cover the whole session lifecycle. Auth needs BROWSERBASE_API_KEY, PROJECT_ID and a model key. The reference repo was archived in July 2026; the hosted endpoint keeps running.
Why this server
- act performs page actions from a plain-language description — no CSS selectors or XPath
- The cloud browser session needs no local resources on the MCP client's machine
- extract returns structured page data instead of raw HTML or a screenshot
- The hosted mcp.browserbase.com endpoint keeps running even after the example repo was archived
