Why create_support_case needs a policy

Creating a support case is a Write operation—it generates a new record in AWS Support system that is reversible (cases can be closed or modified). While the empty description reduces confidence, the name clearly indicates case creation rather than retrieval, execution, or deletion.

From the tool's definition Tool name 'create_support_case' indicates creation of a support case record. Description is empty, limiting certainty.

POLICY

How to control create_support_case

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 create_support_case:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_support_case": {
      "limits": [
        {
          "counter": "create_support_case_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_support_case stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. 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.
