WHAT IT DOES

What create_queue does on AWS

AI agents use create_queue to create or update resources in AWS, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AWS environment.

RISK

Why create_queue is rated Medium

Creating a queue (likely SQS or similar AWS messaging service) is a reversible Write operation that modifies infrastructure state. While not immediately destructive, it commits resources and could enable message routing to unintended destinations if misused by an agent. Severity is high due to potential for service disruption and resource proliferation.

From the tool's definition Tool name 'create_queue' indicates creation of a queue resource; sibling tools include policy attachment and user management operations suggesting infrastructure/service control context; no description available to confirm scope

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_queue safely

PolicyLayer is an MCP gateway: it sits between your AI agents and AWS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_queue, this is the rule to start with:

create_queue Rate-limited

create_queue 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.

View as policy code

policy.json

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

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect AWS, apply this rule, and every create_queue call is checked against it from then on.
