WHAT IT DOES

What stream_group_delete_consumer does on AWS

AI agents call stream_group_delete_consumer to permanently remove resources in AWS — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Critical Risk

Why stream_group_delete_consumer needs a policy

The tool performs an irreversible deletion operation ('delete consumer from group'). Once executed, the consumer is removed and cannot be recovered without re-adding it manually. This is a destructive action that modifies system state permanently.

From the tool's definition Tool name contains 'delete'; description states 'Delete consumer from group.' This is an irreversible removal of a consumer entity from a Kafka/stream processing group.

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

POLICY

How to control stream_group_delete_consumer

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 stream_group_delete_consumer:

policy.json

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

stream_group_delete_consumer 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 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
