THE RISK

Why cache_delete_multi needs a policy

This tool irreversibly deletes data from a cache system. Although cache data is typically recoverable through regeneration or upstream sources, the deletion operation itself is destructive and cannot be directly undone. The ability to delete multiple values in one operation increases blast radius if misused by an agent, warranting high severity.

From the tool's definition Tool name contains 'delete' and description states 'Delete multiple values from the cache'; the alias 'delete_many' reinforces that this performs deletion operations on cached data.

POLICY

How to control cache_delete_multi

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Labs amazon-qindex MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for cache_delete_multi:

policy.json

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

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

Point your MCP client (Claude, Cursor, anything) at your gateway URL.
