AI agents call cost-anomaly 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 tool name suggests retrieval and analysis of AWS cost data to detect anomalies. This appears to be a Read operation (querying/analyzing existing data with no side effects). However, the confidence is low because the description is empty, making it difficult to determine the precise scope and whether it could perform other actions like modifying billing settings or triggering cost controls.
From the tool's definition Tool name 'cost-anomaly' suggests querying or analyzing cost data for anomalies, which is a read operation. No explicit destructive, financial, or execute operations implied by the name alone.
Documented attack patterns abuse exactly the kind of access cost-anomaly 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 cost-anomaly:
{
"version": "1",
"default": "deny",
"tools": {
"cost-anomaly": {}
}
}cost-anomaly is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

cost-anomaly. 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 cost-anomaly: 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.
cost-anomaly 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 cost-anomaly 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 cost-anomaly. 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.
cost-anomaly 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.
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.
