Why QBusinessQueryTool needs a policy

With no description available, classification is highly uncertain. The name suggests a query (Read) operation against Amazon Q Business, but given the server context (SNS/SQS management) and the ambiguity of an empty description, confidence is very low. Defaulting to Other with minimal severity pending more information.

From the tool's definition Tool description is empty and uninformative; the name 'QBusinessQueryTool' suggests a query/read operation but cannot be confirmed.

POLICY

How to control QBusinessQueryTool

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 QBusinessQueryTool:

policy.json

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

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