Hosting

hosted

Transport

Streamable HTTP

Endpoint

https://mcp.browserbase.com

Authentication

Browserbase account credentials/authentication required; exact account setup is publisher-specific.

Requirements

• Browserbase account and API key
• Browserbase Project ID for local package
• MCP client supporting Streamable HTTP for hosted use or stdio for local use
• For local setup, required package environment values include BROWSERBASE_API_KEY, BROWSERBASE_PROJECT_ID, and GEMINI_API_KEY

Setup steps

1. Get the Browserbase API key from the official dashboard.
2. For hosted setup, add https://mcp.browserbase.com/mcp to the client and include browserbaseApiKey=<YOUR_API_KEY> as documented; treat query-string credentials as secrets and avoid sharing resulting URLs.
3. For local setup, use the official npm package @browserbasehq/mcp with the documented BROWSERBASE_API_KEY, BROWSERBASE_PROJECT_ID, and GEMINI_API_KEY values, or the documented Docker image.
4. Reload the client and verify by starting a browser session and navigating to a harmless public page.
5. Pass the returned sessionId on calls when the client does not preserve MCP session IDs between requests.
