AI agents call ListAHORuns to retrieve information from Awslabs Amazon Sns Sqs without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'List' prefix conventionally indicates query/retrieval operations that retrieve data without modification. Without a description, confidence is reduced but the naming pattern strongly suggests this is a Read operation that retrieves or enumerates runs (likely related to AHO - Amazon Hail Operations or similar) without side effects.
From the tool's definition Tool name 'ListAHORuns' suggests listing/querying operations. The empty description prevents full certainty, but 'List' prefix is a strong indicator of read-only retrieval without side effects.
Documented attack patterns abuse exactly the kind of access ListAHORuns gives an agent:
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 ListAHORuns:
{
"version": "1",
"default": "deny",
"tools": {
"ListAHORuns": {}
}
}ListAHORuns is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

ListAHORuns. It is categorised as a Read tool in the Awslabs Amazon Sns Sqs MCP Server, which means it retrieves data without modifying state.
Register the Awslabs Amazon Sns Sqs MCP server in PolicyLayer and add a rule for ListAHORuns: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Awslabs Amazon Sns Sqs. Nothing to install.
ListAHORuns is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the ListAHORuns rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for ListAHORuns. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
ListAHORuns is provided by the Awslabs Amazon Sns Sqs MCP server (awslabs.amazon-sns-sqs-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
