THE RISK

Critical Risk

Why removeRssFeed needs a policy

This tool irreversibly deletes a configured RSS feed entry from the database. While the blast radius is limited to feed configuration (not user data or financial assets), the action cannot be undone without manual restoration. Deletion from a database is inherently destructive.

From the tool's definition Tool name is 'removeRssFeed' and description states 'Remove an RSS feed from the database' — the verb 'remove' indicates deletion/removal of data from persistent storage.

POLICY

How to control removeRssFeed

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "removeRssFeed"
  ]
}

removeRssFeed disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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