Official rulings

1 ruling · in English, source Scryfall

Despite that fact that it can produce mana as it resolves, Klauth's triggered ability is not a mana ability because its trigger condition wasn't the activation or resolution of an activated mana ability. This means that it uses the stack and can be responded to. Notably, players can respond by destroying attacking creatures to reduce the amount of mana produced.
