What mysql_delete does on Db

AI agents call mysql_delete to permanently remove resources in Db — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

Critical Risk

Why mysql_delete needs a policy

MySQL DELETE is a destructive operation that permanently removes records from a database. While the server mentions 'runtime protections' and 'graded security modes' which may mitigate some risk, the fundamental capability is irreversible data deletion. This is more severe than Write (which is reversible) and ranks as Destructive.

From the tool's definition Tool name explicitly states 'delete' and description confirms '执行 MySQL DELETE 删除操作' (executes MySQL DELETE operation). DELETE operations irreversibly remove data from database rows.

Documented attack patterns abuse exactly the kind of access mysql_delete gives an agent:

How to control mysql_delete

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

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "mysql_delete"
  ]
}

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

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