THE RISK

Critical Risk

Why sorted_set_popmin needs a policy

A pop operation both removes and returns data. The removal is destructive and cannot be undone; the members are permanently deleted from the sorted set. This warrants a Destructive classification with high severity since an AI agent misusing this tool could irreversibly delete data from a data store.

From the tool's definition 'Remove and return members with lowest scores' — the removal is irreversible (pop operation permanently deletes the members from the sorted set).

POLICY

How to control sorted_set_popmin

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon ECS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for sorted_set_popmin:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "sorted_set_popmin"
  ]
}

sorted_set_popmin disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Amazon ECS MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
