Gmod Server Tools Help

Hello all hopefully this is the right spot to post but anyways when i join my favorite server (oshii) on gmod there are a few tools missing that the server has the other players have but that i dont have, and there is a buddies under utilites that i dont have and eveyone else has so could someone help me fix this it would be very much appreciated ty! :).
