I don't know of any tool that will do that but this will work.

Make a copy of your MOHAA icon then right click on it. Double-click on properties and in the target field scroll over to the end and add +set cl_playintro 0 +connect nnn.nnn.nnn.nnn:12203
Rename the icon for the server.

Now when you double-click on the icon your game will start without the intro and connect to the IP address.

To add a password add "+password AaBbCcDd" without the quotes, after the playintro 0, and before the +connect
