THE RISK

Why delete_user_policy needs a policy

Delete operations are classified as Destructive because they irreversibly remove data or configurations. Deleting a user policy removes access permissions that cannot be automatically restored without reapplication. The high severity reflects that unauthorized deletion of IAM policies could grant or revoke access unintentionally, affecting system security and user permissions.

From the tool's definition Tool name is 'delete_user_policy' which contains the verb 'delete', indicating irreversible removal of a resource (an IAM user policy). The tool description is empty, providing no mitigating context.

POLICY

How to control delete_user_policy

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

policy.json

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

delete_user_policy 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 Labs amazon-keyspaces 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.
