Browserbase MCP Server
The Browserbase MCP server, powered by Stagehand, lets AI agents drive a real cloud browser with natural language. Agents can start and end browser sessions, navigate to URLs, act on pages, observe actionable elements, and extract structured data — enabling reliable web automation, scraping, and form-filling in the cloud.

Note where the key goes: Browserbase documents it as a query parameter on the URL, not a header — the opposite of what Firecrawl asks for, and a reason to keep this URL out of anything you share or commit. Driving a non-default model adds &modelName=...&modelApiKey=... to the same URL. The stdio alternative is npx @browserbasehq/mcp with BROWSERBASE_API_KEY and GEMINI_API_KEY.
