THE RISK

Low Risk

Why cache_get_many needs a policy

This tool performs a read-only operation—retrieving cached values. It has no capacity to modify, delete, or execute code. The blast radius of misuse is minimal, limited to potential information disclosure of cached data. Low severity reflects the typical low-sensitivity nature of cache contents and the absence of destructive or operational side effects.

From the tool's definition Tool name 'cache_get_many' and description 'Get multiple values from the cache' indicate a retrieval operation with no modification or side effects.

POLICY

How to control cache_get_many

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

policy.json

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

cache_get_many 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 Amazon EKS 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.
