## Why delete_object is rated Critical

This tool permanently removes objects from Tencent Cloud Object Storage without possibility of reversal. The action cannot be undone and results in data loss. Even though it operates on a single object rather than bulk deletion, the irreversible nature of deletion operations places it in the Destructive category, which ranks above Execute, Write, and Read in severity hierarchy.

From the tool's own definition: "Tool name 'delete_object' and description '删除COS中的对象' (delete object in COS) indicate irreversible deletion of data from cloud storage."

## Use case

AI agents call delete_object to permanently remove resources in Tencent Cloud COS MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
