A list of tags applied to the resource.
AI agents call ListTagsForResource 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.
This tool retrieves tag metadata from an SNS/SQS resource. It performs a query operation with no side effects, data modification, or execution capability. The severity is low as tag information is typically non-sensitive metadata, and the blast radius of misuse is minimal.
From the tool's definition Tool name 'ListTagsForResource' and description 'A list of tags applied to the resource' indicate a read-only operation that retrieves metadata without modifying state.
Documented attack patterns abuse exactly the kind of access ListTagsForResource 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 ListTagsForResource:
{
"version": "1",
"default": "deny",
"tools": {
"ListTagsForResource": {}
}
}ListTagsForResource is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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

Yes. Add a rate_limit block to the ListTagsForResource 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 ListTagsForResource. 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.
ListTagsForResource 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.
