AI agents call sorted_set_range to retrieve information from AWS without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a range of members from a sorted set data structure. It only reads data based on index range parameters with no side effects, making it a straightforward Read operation with low severity.
From the tool's definition Get range of members from sorted set
Documented attack patterns abuse exactly the kind of access sorted_set_range gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AWS, and nothing reaches the server without passing your rules. This is the rule we recommend for sorted_set_range:
{
"version": "1",
"default": "deny",
"tools": {
"sorted_set_range": {}
}
}sorted_set_range is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get range of members from sorted set. Args: key: The name of the key start: Start index (inclusive) stop: Stop index (inclusive) withscores: Include scores in result reverse: Return results in reverse order Returns: List of members (with scores if requested) or error message. It is categorised as a Read tool in the AWS MCP Server, which means it retrieves data without modifying state.
Register the AWS MCP server in PolicyLayer and add a rule for sorted_set_range: 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. Nothing to install.
sorted_set_range 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 sorted_set_range 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 sorted_set_range. 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.
sorted_set_range is provided by the AWS MCP server (@awslabs/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AWS, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
