Why list_sub_check_rule_results needs a policy

The tool name suggests retrieving or listing check rule results, which is a read-only query operation. However, confidence is moderately reduced due to the empty description preventing verification of actual functionality. The 'list' prefix combined with context of an EKS management server indicates data retrieval rather than modification, deletion, or execution of arbitrary operations.

From the tool's definition Tool name 'list_sub_check_rule_results' contains 'list' which is a typical Read operation pattern for retrieving results without modification.

POLICY

How to control list_sub_check_rule_results

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 list_sub_check_rule_results:

policy.json

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

list_sub_check_rule_results 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.
