WHAT IT DOES

What create_agent_runtime does on AWS Labs amazon-qindex MCP Server

AI agents invoke create_agent_runtime to trigger actions in AWS Labs amazon-qindex 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.

Why create_agent_runtime needs a policy

The name implies provisioning or launching an agent runtime, which is an Execute-level operation (spinning up infrastructure/processes). However, because the description is empty, confidence is reduced. Given the server context (AWS/Amazon Q Business) and the pattern of sibling tools, this likely creates a new runtime resource.

From the tool's definition Tool name 'create_agent_runtime' suggests creation/instantiation of an agent runtime environment; description is empty and uninformative.

Documented attack patterns abuse exactly the kind of access create_agent_runtime gives an agent:

POLICY

How to control create_agent_runtime

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Labs amazon-qindex MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_agent_runtime:

policy.json

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

create_agent_runtime 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
