AI agents call liara_delete_snapshot to permanently remove resources in Liara MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a VM snapshot is a destructive action that permanently removes infrastructure backup data. While not as critical as deleting a running VM or database, snapshots are often the only recovery mechanism for data loss or corruption. Unauthorized or mistaken deletion could prevent recovery of entire application states, making this a high-severity destructive operation.
From the tool's definition Tool name contains 'delete' and description states 'Delete a VM snapshot' — this irreversibly removes a snapshot, which cannot be undone.
Documented attack patterns abuse exactly the kind of access liara_delete_snapshot gives an agent:
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_delete_snapshot:
{
"version": "1",
"default": "deny",
"hide": [
"liara_delete_snapshot"
]
}liara_delete_snapshot disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

liara_delete_snapshot is provided by the Liara MCP Server MCP server (razavioo/liara-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Liara MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
