AI agents call delete_worksheet to permanently remove resources in Office Editor — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes a worksheet from an Excel file, which is an irreversible operation that destroys data. Although the scope is limited to a single worksheet (not the entire file), the destruction of all data within that worksheet and inability to undo makes this Destructive rather than Write. The high severity reflects the potential data loss if an AI agent mistakenly deletes the wrong worksheet.
From the tool's definition Tool name 'delete_worksheet' and description '从Excel工作簿中删除指定的工作表' (delete specified worksheet from Excel workbook) indicate irreversible deletion of data. The operation removes a worksheet and cannot be undone.
Documented attack patterns abuse exactly the kind of access delete_worksheet gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Office Editor, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_worksheet:
{
"version": "1",
"default": "deny",
"hide": [
"delete_worksheet"
]
}delete_worksheet disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
