The rule that runs stream_group_delete_consumer safely
PolicyLayer is an MCP gateway: it sits between your AI agents and AWS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For stream_group_delete_consumer, this is the rule to start with:
stream_group_delete_consumer is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect AWS, apply this rule, and every stream_group_delete_consumer call is checked against it from then on.
