WHAT IT DOES

What create_vm_snapshot does on CloudStack MCP Server

AI agents use create_vm_snapshot 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 create_vm_snapshot needs a policy

Creating a VM snapshot is a reversible write operation that creates new infrastructure state but does not permanently destroy data or execute arbitrary code. While snapshotting can consume significant storage resources and has operational implications in a cloud environment, it remains a standard write-category operation.

From the tool's definition Tool name 'create_vm_snapshot' and description 'Create virtual machine snapshot' indicate creation of a new snapshot resource. This is a write operation that creates a new data object (snapshot) but is reversible through snapshot deletion.
