Find SQS queues with no messages sent or received.
AI agents call find_unused_sqs_queues to retrieve information from AWS FinOps MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries AWS SQS queue metrics to identify unused queues based on message activity. It performs no modifications, deletions, or execution of external operations—it only reads and analyzes existing data. The purpose is cost optimization discovery, not resource management.
From the tool's definition Tool name 'find_unused_sqs_queues' and description 'Find SQS queues with no messages sent or received' indicate a query/detection operation that retrieves information about queue usage metrics without modifying or deleting any resources.
Attacks that exploit this kind of access
Find SQS queues with no messages sent or received. It is categorised as a Read tool in the AWS FinOps MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS FinOps MCP Server MCP server in PolicyLayer and add a rule for find_unused_sqs_queues: 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 AWS FinOps MCP Server. Nothing to install.
find_unused_sqs_queues 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 find_unused_sqs_queues 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 find_unused_sqs_queues. 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.
find_unused_sqs_queues is provided by the AWS FinOps MCP Server MCP server (prashantgupta123/aws-pillar-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
