Why restore_database_backup needs a policy

Restoring a database from backup is a reversible write operation—it overwrites current database contents with historical data, but the action can be undone by creating a new backup or restoring to a different point in time. It is not Destructive because the original data is not permanently lost (backups exist), and the operation is theoretically reversible.

From the tool's definition Tool name 'restore_database_backup' and description 'Restore a MySQL database from a backup file' indicate the tool modifies database state by restoring data from a backup.

POLICY

How to control restore_database_backup

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "restore_database_backup": {
      "limits": [
        {
          "counter": "restore_database_backup_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

restore_database_backup stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
