THE RISK

Low Risk

Why get_page_metadata needs a policy

This tool only queries and retrieves publicly available metadata from web pages. It has no side effects, does not execute code, does not modify data, and does not consume financial resources. The blast radius of misuse is minimal since metadata is already public and the tool cannot interact with page functionality or user data beyond what is visible in HTML meta tags.

From the tool's definition Tool description states it 'Extract[s] meta tags, title, description, keywords from web pages' — purely data retrieval with no modification or execution of commands.

POLICY

How to control get_page_metadata

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_page_metadata": {}
  }
}

get_page_metadata is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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