Why track_changes_detailed needs a policy

This tool performs read-only operations: fetching web page content at different points in time and performing diff analysis to identify changes. Diff analysis is a computational comparison task with no side effects. It aligns with the Read category (retrieves or queries data; no side effects). The context of a web scraping server reinforces that this is content analysis rather than manipulation.

From the tool's definition Tool name 'track_changes_detailed' and description 'Track detailed changes in web page content with diff analysis' indicate passive observation and comparison of web content.

POLICY

How to control track_changes_detailed

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 track_changes_detailed:

policy.json

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

track_changes_detailed 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.
