The only way to do that would be to have some script that would either read the "weapons/" folder (not recommended) or to read the "weapons" variable (serverside) which is a list of all weapons on the NPC Server.

Do the latter using a loop or so like someone previously suggested. Not a very good use of your NPC Server's CPU though.

And no, there is no event for when a new WNPC is added to the NPC Server (other then locally with-in that script, but that doesn't help you).
