Clear all messages from the SpamAssassin spam box
AI agents call clear_spam_box to permanently remove resources in cPanel MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data (spam messages) in bulk with no stated recovery mechanism. While spam is often unwanted, the tool's destructive nature and inability to undo the action places it in the Destructive category rather than Write. The high severity reflects that an AI agent could inadvertently delete legitimate messages incorrectly flagged as spam, causing data loss for the account holder.
From the tool's definition 'Clear all messages from the SpamAssassin spam box' — irreversibly deletes all spam messages without recovery option or undo capability.
