What mysql_truncate_table does on Mysql
AI agents call mysql_truncate_table to permanently remove resources in Mysql, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why mysql_truncate_table is rated Critical
TRUNCATE permanently and irreversibly deletes all rows from a table. This is a destructive operation with no undo capability, making it critical severity. The server description emphasizes 'read-only queries' and 'monitoring', yet this tool allows destructive mutations, representing significant blast radius if misused by an AI agent (complete data loss).
From the tool's definition Tool name 'mysql_truncate_table' and description 'remove all rows quickly' indicate irreversible deletion of all table data. TRUNCATE is a DDL operation that cannot be undone without backups.

mysql_truncate_table is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
