Why extract_images needs a policy

This tool retrieves image data and associated metadata from web pages. It performs no side effects, creates no new data, modifies nothing, executes no code, and destroys nothing. It is a straightforward read operation consistent with other analysis tools on this server (analyze_cookies, analyze_readability, etc.).

From the tool's definition Tool name 'extract_images' and description 'Extract all images from a web page with metadata' indicate data retrieval only.

POLICY

How to control extract_images

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 extract_images:

policy.json

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

extract_images 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.
