AI agents call wechat_permanent_media to permanently remove resources in WeChat Official Account MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool supports deletion of permanent media materials ('永久素材'), which is irreversible. Per the severity rules, Destructive is more severe than Write/Read, so the presence of delete capability drives the classification. Blast radius is high because permanent media assets may be linked to published articles and other content; deleting them could break live content across the WeChat Official Account.
