AI agents call delete_ppt to permanently remove resources in ChatPPT-MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes PPT documents from the RAG index, which cannot be undone without re-adding them. This is a destructive operation affecting data persistence. Severity is high because losing indexed documents could disrupt document availability and analysis workflows, though financial impact is unlikely unless documents contain critical business content.
From the tool's definition Tool name 'delete_ppt' and description '从RAG索引中删除指定的PPT文档' (delete specified PPT documents from RAG index) indicate irreversible removal of indexed documents.
Documented attack patterns abuse exactly the kind of access delete_ppt gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ChatPPT-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_ppt:
{
"version": "1",
"default": "deny",
"hide": [
"delete_ppt"
]
}delete_ppt disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
