In your Ark Ascended page you indicate you do not know if it is possible to send items to players via RCON. It is in fact possible with command “GiveItemToPlayer 999999999 “Blueprint’/Game/PrimalEarth/CoreBlueprints/Items/Armor/Metal/PrimalItemArmor_MetalGloves.PrimalItemArmor_MetalGloves’” 1 1 0”. Details here: https://ark.wiki.gg/wiki/Console_commands#GiveItemToPlayer.
The tricky part is the only way I could find to get the right player ID number is from inside the games own admin interface while logged into the server. But the command certainly does work via RCON.
