WHAT SCROLL_DOWN ON MCP BROWSER USE DOES

AI agents invoke scroll_down to trigger actions in Mcp Browser Use. 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.

THE RISK

High Risk

This tool performs a browser action (scrolling) that triggers an external operation within a live browser session. While scrolling itself is low-impact, it is a browser execution action rather than a pure read, and could be used to navigate to content or trigger lazy-loaded elements. Severity is low as misuse has minimal blast radius.

From the tool's definition Scroll down the page by the specified amount... browser-use, allowing clients to utilize existing LLMs without requiring additional API keys

HOW TO CONTROL SCROLL_DOWN

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Browser Use, and nothing reaches the server without passing your rules. This is the rule we recommend for scroll_down:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "scroll_down": {
      "limits": [
        {
          "counter": "scroll_down_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

scroll_down stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Mcp Browser Use — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
