WHAT IT DOES

What resize_page does on Chrome DevTools MCP

AI agents invoke resize_page to trigger actions in Chrome DevTools MCP. 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.

RISK

Why resize_page is rated High

Resizing a browser page is an external operation affecting a live browser session. It falls under Execute as it triggers a browser-side action, but has low blast radius since it only changes display dimensions and is easily reversible.

From the tool's definition Resizes the selected page — triggers a browser action that changes the viewport/window dimensions of a live Chrome page

RECOMMENDED RULE

The rule that runs resize_page safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Chrome DevTools MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For resize_page, this is the rule to start with:

resize_page Rate-limited

resize_page 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.

policy.json

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

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Chrome DevTools MCP, apply this rule, and every resize_page call is checked against it from then on.

What risk level is resize_page? +
