What mysql_delete_data does on Mysql
AI agents call mysql_delete_data 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_delete_data is rated Critical
Deletion of database records cannot be undone without a backup restore. This represents the highest severity action in database operations. Although the server description claims to be 'read-only' and 'production-ready' with 'secure' endpoints, the presence of this destructive tool directly contradicts the read-only claim.
From the tool's definition Tool name is 'mysql_delete_data' with description 'Delete data from a table.' The verb 'delete' and explicit mention of removing data from a table indicates irreversible data destruction.
Attacks that exploit this kind of access
The rule that runs mysql_delete_data safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mysql, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mysql_delete_data, this is the rule to start with:
mysql_delete_data 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, apply this rule, and every mysql_delete_data call is checked against it from then on.
