WHY IT NEEDS A POLICY

Why create_configuration needs a policy

This tool creates a new configuration entity for an AmazonMQ broker. Configuration creation is a write operation that modifies system state by adding a new resource, but is generally reversible (the configuration can be deleted or updated later). It does not execute arbitrary code, delete data irreversibly, or move financial resources.

From the tool's definition Tool name 'create_configuration' and description 'Create configuration for AmazonMQ broker' indicate creation of a new configuration resource, a reversible write operation.
