删除 TOS 对象
AI agents call tos_delete_object to permanently remove resources in TOS MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool directly deletes objects from cloud storage without recovery options. This is an irreversible operation that destroys data, placing it in the Destructive category. Severity is high because unauthorized or misdirected deletion could result in permanent loss of user data, though the impact is scoped to individual objects rather than infrastructure-wide.
From the tool's definition Tool name tos_delete_object and description '删除 TOS 对象' (delete TOS object) indicate irreversible deletion of stored objects in Volcengine's object storage service.
