THE RISK

Medium Risk

Why sorted_set_remove_by_rank needs a policy

The tool modifies data by removing members from a sorted set based on rank criteria. While removal is occurring, it is reversible (data can be restored if backed up or re-added), distinguishing it from truly destructive operations. The scope appears limited to a specific data structure rather than cascading system-wide deletions.

From the tool's definition Tool name 'sorted_set_remove_by_rank' and description 'Remove members by rank range' indicate a data modification operation that deletes members from a sorted set structure, which is a reversible write operation (members can be re-added).

POLICY

How to control sorted_set_remove_by_rank

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "sorted_set_remove_by_rank": {
      "limits": [
        {
          "counter": "sorted_set_remove_by_rank_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

sorted_set_remove_by_rank 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.
