Description of your suggestion
So when you buy something in the shop like a kit starter it asks you what command should it execute in console (Atleast in Minecraft version of Azuriom it does that), but not all the plugins are designed to be compatible through in-game commands. So i suggest you add a new feature that instead of executing a command in console executes it in MySQL as query command.
Advantages
Adds support for more plugins and their features.
