Delete a message from a chat.
AI agents call delete_message to permanently remove resources in Telegram Mcp Kit — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Message deletion is an irreversible action that permanently removes data from a chat. This falls squarely into the Destructive category as it cannot be undone or rolled back. While the blast radius is limited to a single message in a specific chat (not system-wide), the permanent loss of data and potential impact on communication history, evidence preservation, or user experience justifies a 'high' severity rating.
From the tool's definition Tool name is 'delete_message' with description 'Delete a message from a chat.' The verb 'delete' and the irreversible nature of message deletion clearly indicate a destructive operation that cannot be undone.
