What mysql_migration_rollback does on Mysql Mcp
AI agents call mysql_migration_rollback to permanently remove resources in Mysql Mcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why mysql_migration_rollback is rated Critical
Rolling back a migration reverts database schema changes and potentially destroys data that was created under the migrated schema. This is an irreversible operation in practice — data written to new columns/tables may be dropped, and the rollback cannot be undone without re-running the migration and potentially losing data permanently. Combined with enterprise MySQL context, the blast radius is critical.

The rule that runs mysql_migration_rollback safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mysql Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mysql_migration_rollback, this is the rule to start with:
mysql_migration_rollback is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Mysql Mcp, apply this rule, and every mysql_migration_rollback call is checked against it from then on.
