THE RISK

Why get_cache_stats needs a policy

This tool retrieves internal cache statistics and metrics. It performs a read-only query of system state data. There is no data modification, deletion, execution of external commands, or financial impact. The minimal severity reflects that cache statistics are non-sensitive operational metadata with no blast radius if accessed by an AI agent.

From the tool's definition Tool name 'get_cache_stats' and description 'Get cache performance statistics including total entries, pending requests, and data type breakdown' indicate retrieval of monitoring/diagnostic data with no modification or side effects.

POLICY

How to control get_cache_stats

PolicyLayer is an MCP gateway — it sits between your AI agents and Discogs 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 Discogs 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.
