WHAT IT DOES

What enable_vm_ha does on CloudStack MCP Server

AI agents use enable_vm_ha to create or update resources in CloudStack MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CloudStack MCP Server environment.

WHY IT NEEDS A POLICY

Why enable_vm_ha needs a policy

This tool modifies a VM's high availability setting, which is a Write operation (configuration change to infrastructure). While it affects availability posture, the change is reversible—HA can be disabled. It does not delete data, execute arbitrary code, or move funds.

From the tool's definition Tool name 'enable_vm_ha' and description 'Enable high availability for virtual machine' indicate a configuration modification operation that modifies VM settings (HA state) reversibly.
