THE RISK

Low Risk

Why aggregate needs a policy

With no description provided, it's impossible to determine what this tool does with confidence. The name 'aggregate' could imply read/query operations (aggregating data/metrics), but on an SNS/SQS server context it remains ambiguous. Lowering confidence significantly due to lack of evidence; defaulting to Other with low severity.

From the tool's definition Tool name is 'aggregate' and the description is empty or uninformative.

POLICY

How to control aggregate

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 aggregate:

policy.json

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

aggregate gets a rate cap, and 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.

FAQ

Questions about aggregate

What does the aggregate tool do? +

aggregate. It is categorised as a Other tool in the Awslabs Amazon Sns Sqs MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on aggregate? +

Register the Awslabs Amazon Sns Sqs MCP server in PolicyLayer and add a rule for aggregate: 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.

What risk level is aggregate? +

aggregate is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit aggregate? +

Yes. Add a rate_limit block to the aggregate 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.

How do I block aggregate completely? +

Set action: deny in the PolicyLayer policy for aggregate. 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.

What MCP server provides aggregate? +

aggregate 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.

Enforce policy on every Awslabs Amazon Sns Sqs tool call.

Start from Awslabs Amazon Sns Sqs, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
