WHY IT NEEDS A POLICY

Why create_domain_name needs a policy

The tool creates a domain name, which is a reversible write operation that establishes a new resource configuration. While the description is empty (lowering confidence slightly), the name and server context clearly indicate resource provisioning rather than querying (Read) or deletion (Destructive).

From the tool's definition Tool name is 'create_domain_name' which indicates creating/provisioning a domain name resource. Server description mentions 'provision and manage your AMQ brokers', suggesting write operations for resource creation.
