Analysis summary

Browserbase MCP Server is an officially published MCP server from Browserbase. Anomity scores its risk at 10 out of 100 (low).

Browserbase runs headless browsers in the cloud and exposes them to agents over MCP, so browser automation happens on their infrastructure rather than on the developer's machine — useful for scale, sessions, and not handing a local browser to a model.

It declares browser control and outbound network access. Moving the browser off your machine changes the risk shape rather than removing it: the automation no longer touches your local profile, but the pages, credentials, and session state now live with a third party. For authenticated automation, that means your logged-in sessions exist in someone else's infrastructure — a reasonable trade for many workloads, but one to make deliberately.

Capabilities

Every capability the entry declares, with the security implication of each.

  • browser:control Browser control
    Drives a browser session. Combined with credential access can impersonate the user on web services.
  • network:outbound Outbound network
    Can make outbound network requests. Required for hosted model providers and remote APIs; also the path for data exfiltration if combined with read access.
