THE RISK

Critical Risk

Why mysql_delete_data needs a policy

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.

POLICY

How to control mysql_delete_data

PolicyLayer is an MCP gateway — it sits between your AI agents and Mysql, and nothing reaches the server without passing your rules. This is the rule we recommend for mysql_delete_data:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "mysql_delete_data"
  ]
}

mysql_delete_data disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Mysql — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
