WHAT IT DOES

What restore_virtual_machine does on CloudStack MCP Server

AI agents use restore_virtual_machine 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.

RISK

Why restore_virtual_machine is rated Medium

Restore is a write operation that modifies VM state by reverting it to a previous configuration or snapshot. While it changes infrastructure, it is generally reversible (the current state can be snapshotted again). This is less severe than destructive operations (which are irreversible) but more severe than simple data creation.

From the tool's definition Tool name 'restore_virtual_machine' and description 'Restore a virtual machine' indicates modification of VM state. Restore operations typically revert a VM to a previous state, which is a reversible write operation rather than irreversible deletion.

RECOMMENDED RULE

The rule that runs restore_virtual_machine safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CloudStack MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For restore_virtual_machine, this is the rule to start with:

restore_virtual_machine Rate-limited

restore_virtual_machine stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
