Why get_cache_stats needs a policy

This tool retrieves cache statistics for monitoring purposes only. It has no side effects, does not modify data, does not execute arbitrary code, and does not delete or move resources. The read-only nature of performance monitoring queries makes this a low-severity Read operation.

From the tool's definition Tool name 'get_cache_stats' and description 'Get cache statistics for monitoring server performance' indicate a read-only query operation that retrieves performance metrics without modifying data or triggering external operations.

POLICY

How to control get_cache_stats

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

policy.json

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

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