WHAT IT DOES

What browserbeam_scroll does on Browserbeam MCP Server

AI agents invoke browserbeam_scroll to trigger actions in Browserbeam MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why browserbeam_scroll needs a policy

This tool performs a browser action (scrolling) within a live browser session. It triggers an external operation in a real browser environment. While scrolling itself has minimal blast radius, it is a browser interaction/execution action rather than a passive read. It cannot directly destroy data or move money, making Execute the most appropriate category.

From the tool's definition Scroll the page by direction, to top/bottom, or scroll an element into view
