Returns a list of Timestream for InfluxDB DB clusters filtered by status (case-insensitive).
AI agents call ListClustersByStatus 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 queries and returns information about Timestream for InfluxDB clusters filtered by a status parameter. It performs a read-only operation with no side effects—it neither modifies, executes external operations, deletes data, nor involves financial transactions. The blast radius of misuse is minimal (information disclosure only).
From the tool's definition Tool name 'ListClustersByStatus' and description 'Returns a list' indicate a retrieval operation with no modification of data. The verb 'list' is explicitly Read-category per the rules.
Documented attack patterns abuse exactly the kind of access ListClustersByStatus 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 ListClustersByStatus:
{
"version": "1",
"default": "deny",
"tools": {
"ListClustersByStatus": {}
}
}ListClustersByStatus is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns a list of Timestream for InfluxDB DB clusters filtered by status (case-insensitive). 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 ListClustersByStatus: 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.
ListClustersByStatus 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 ListClustersByStatus 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 ListClustersByStatus. 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.
ListClustersByStatus 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.
