Nemeth, who will spend at least the 2015 MLS season with Sporting, is expected to fit well in head coach Peter Vermes' attacking plans for next year's campaign.
"Krisztian is a player who has extensive experience playing in a 4-3-3 [system]," Vermes said in a statement released by the club.
"He also fits well in the overall model of play for Sporting Kansas City and we look forward to his adaptation."
He joins Chilean goalkeeper Luis Marin at Sporting Park after SKC confirmed the signing of the 31-year old on Thursday afternoon.
