THE RISK

Low Risk

Why stream_info needs a policy

This tool retrieves stream metadata or status information without creating, modifying, or deleting any resources. It is a passive query operation that poses minimal security risk if misused by an AI agent, as it cannot alter system state or incur financial obligations.

From the tool's definition Tool name 'stream_info' and description 'Get information about stream' indicate a retrieval operation with no side effects. The verb 'Get' and lack of any modification language confirm read-only intent.

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

POLICY

How to control stream_info

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 stream_info:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "stream_info": {}
  }
}

stream_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Awslabs Amazon Sns Sqs — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
