Why sorted_set_remove_by_score needs a policy

This tool permanently removes data from a sorted set based on a score range. Deletion of data records is irreversible — once members are removed, they cannot be recovered without a backup. The bulk nature (range-based removal) increases the blast radius, as a misconfigured score range could delete large amounts of data unintentionally.

How to control sorted_set_remove_by_score

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_remove_by_score:

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "sorted_set_remove_by_score"
  ]
}

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

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