WHY IT NEEDS A POLICY

Why create_resource needs a policy

The 'create_resource' tool on an MQ provisioning server most likely creates message broker instances or related infrastructure. This is a Write operation—it creates new resources that can be modified or deleted later. Severity is high because provisioning cloud infrastructure resources can incur significant costs and consume account quota, though it is reversible (unlike Destructive operations).

From the tool's definition Tool name 'create_resource' on Amazon MQ MCP Server indicates creation of broker resources. Server description states the server provisions and manages AMQ brokers. No description provided for the specific tool, limiting precision.
