Remove and return members with lowest scores.
AI agents use sorted_set_popmin to create or update resources in Awslabs Amazon Sns Sqs — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Awslabs Amazon Sns Sqs environment.
This tool modifies data by removing elements (sorted set members) but the operation is reversible in principle—the removed data could be restored from backups or logs, and the action only affects specific low-scoring members rather than entire datasets. While 'Remove' suggests mutation, it does not match 'Destructive' criteria of irreversible deletion without recovery options typical of production data purges.
From the tool's definition Tool name 'sorted_set_popmin' and description 'Remove and return members with lowest scores' indicate a data modification operation that removes elements from a collection.
Documented attack patterns abuse exactly the kind of access sorted_set_popmin 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 sorted_set_popmin:
{
"version": "1",
"default": "deny",
"tools": {
"sorted_set_popmin": {
"limits": [
{
"counter": "sorted_set_popmin_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}sorted_set_popmin stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Remove and return members with lowest scores. It is categorised as a Write tool in the Awslabs Amazon Sns Sqs MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Awslabs Amazon Sns Sqs MCP server in PolicyLayer and add a rule for sorted_set_popmin: 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.
sorted_set_popmin is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the sorted_set_popmin 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_popmin. 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_popmin 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.
