AI agents call liara_delete_app 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 an app is a destructive action that cannot be undone and results in loss of deployed application and associated data. This falls under the Destructive category as the primary effect is irreversible removal of infrastructure.
From the tool's definition Tool name 'liara_delete_app' and description 'Delete an app' indicate irreversible deletion of application resources on the Liara cloud platform.

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_app:
{
"version": "1",
"default": "deny",
"hide": [
"liara_delete_app"
]
}liara_delete_app disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
