WHAT IT DOES

What reboot_virtual_machine does on CloudStack MCP Server

AI agents invoke reboot_virtual_machine to trigger actions in CloudStack MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why reboot_virtual_machine is rated High

Rebooting a virtual machine is an external operation that disrupts running workloads and services. It is not purely destructive (data is not deleted) but it executes an action with significant operational impact. Misuse could cause service outages for any workloads running on the VM, warranting a high severity rating.

From the tool's definition 'Reboot a virtual machine' — triggers an external operation (restart) on a running VM

RECOMMENDED RULE

The rule that runs reboot_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 reboot_virtual_machine, this is the rule to start with:

reboot_virtual_machine Rate-limited

reboot_virtual_machine stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect CloudStack MCP Server, apply this rule, and every reboot_virtual_machine call is checked against it from then on.
