AI agents call ppt_delete_node to permanently remove resources in Ppt — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The 'delete' verb strongly indicates an irreversible destructive action on presentation nodes (likely slides, shapes, or other elements). Deletion cannot be undone programmatically via this API and would result in data loss.
From the tool's definition Tool name 'ppt_delete_node' with 'delete' verb indicates irreversible removal of presentation content; description is empty but context shows this is part of a PowerPoint automation suite with 155 tools for creating and editing presentations.
Documented attack patterns abuse exactly the kind of access ppt_delete_node gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ppt, and nothing reaches the server without passing your rules. This is the rule we recommend for ppt_delete_node:
{
"version": "1",
"default": "deny",
"hide": [
"ppt_delete_node"
]
}ppt_delete_node disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
