Is there a hack client to reconnect?

I've been playing grief games for some time. However, I have the problem that the server (I think 4 o'clock in the morning) is restarted and I get kicked. So I wanted to ask:

Is there a Minecraft client to reconnect and can it still automatically execute commands?

Just stop looking for any hack client and just play legit!

Live with the fact that you will probably not get any further answers to this.

Labymod has an auto connect
