Why validate_ecs_express_mode_prerequisites needs a policy

The description is empty, so classification is based solely on the name. 'Validate' and 'prerequisites' suggest a read/check operation that inspects configuration without modifying state. However, without a description, confidence is very low. Assigning 'Other' with low severity as a validation check is unlikely to have significant blast radius.

From the tool's definition Tool description is empty; tool name 'validate_ecs_express_mode_prerequisites' suggests a validation/check operation

POLICY

How to control validate_ecs_express_mode_prerequisites

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "validate_ecs_express_mode_prerequisites": {
      "limits": [
        {
          "counter": "validate_ecs_express_mode_prerequisites_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

validate_ecs_express_mode_prerequisites gets a rate cap, and everything else on the server is denied unless you say otherwise.
