Why export_page needs a policy

Exporting a page with resources involves driving a browser to load, render, and collect external assets from a specified URL. This is an active browser execution operation, not a simple passive read. Misuse could involve exfiltrating sensitive internal pages, hitting arbitrary URLs, or downloading malicious content.

From the tool's definition Export webpage with resources — triggers a browser automation action that fetches and packages external web content/resources, constituting an external operation whose effects depend on arguments

POLICY

How to control export_page

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

policy.json

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

export_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.

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