THE RISK

Why liara_restore_snapshot needs a policy

Restoring a VM from a snapshot is a destructive operation because it irreversibly overwrites the current state of the virtual machine with the snapshot state. Any data, configurations, or changes made after the snapshot was captured are permanently lost.

From the tool's definition 'Restore a VM from a snapshot' — restoring from a snapshot overwrites the current VM state irreversibly, destroying all data and changes made after the snapshot was taken.

POLICY

How to control liara_restore_snapshot

PolicyLayer is an MCP gateway — it sits between your AI agents and Liara MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for liara_restore_snapshot:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "liara_restore_snapshot"
  ]
}

liara_restore_snapshot disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Liara MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
