WHY IT NEEDS A POLICY

Why add_vmware_cloud needs a policy

Adding a VMware cloud integration to an HPE Morpheus appliance creates new cloud configuration and connectivity, which is a reversible Write operation with significant blast radius (affects multi-tenant infrastructure). While the tool description is empty, the naming pattern and sibling tools (add_cloud, add_syslog_rule) confirm this is a resource creation action.

From the tool's definition Tool name 'add_vmware_cloud' with context from server description indicating capability to 'provision resources' and manage 'cloud infrastructure' through 'Morpheus API calls'. The 'add_' prefix indicates creation/modification of infrastructure resources.
