From the tool's definition Tool name 'search_feed_items' and description 'Search for content across one or more RSS feeds' indicate a query/search operation with no side effects on the feeds or their data.

POLICY

How to control search_feed_items

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

policy.json

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

search_feed_items 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 Rss — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
