THE RISK

Why sorted_set_remove_by_rank needs a policy

The tool explicitly removes members from a sorted set by rank range. Removal of data is irreversible (destructive), and misuse by an AI agent could result in unintended data loss across potentially large rank ranges.

From the tool's definition 'Remove members by rank range' — removes data from a sorted set irreversibly

Documented attack patterns abuse exactly the kind of access sorted_set_remove_by_rank gives an agent:

POLICY

How to control sorted_set_remove_by_rank

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Transform 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",
  "hide": [
    "sorted_set_remove_by_rank"
  ]
}

sorted_set_remove_by_rank 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 AWS Transform 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.
