WHAT IT DOES

What start_security_scan does on AWS Labs Amazon Q Business anonymous mode MCP Server

AI agents invoke start_security_scan to trigger actions in AWS Labs Amazon Q Business anonymous mode MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

THE RISK

High Risk

Why start_security_scan needs a policy

Security scans are Execute-class tools because they trigger external operations (security analysis processes) whose side effects depend on what is scanned and how the scan is configured. While scans themselves are non-destructive reads of system state, initiating them is an active operation that could consume resources, trigger alerts, or expose sensitive information in scan results.

From the tool's definition Tool name 'start_security_scan' indicates initiation of a scanning operation. The tool description is empty, but the name suggests triggering an external security scanning process whose effects depend on runtime arguments and target configuration.

POLICY

How to control start_security_scan

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Labs Amazon Q Business anonymous mode MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for start_security_scan:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "start_security_scan": {
      "limits": [
        {
          "counter": "start_security_scan_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

start_security_scan stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
