MK-677 increases growth hormone because of its similar chemical structure to ghrelin, a naturally occurring neuropeptide in the central nervous system. In a sense MK-677 mimics ghrelin and is able to bind to the brains ghrelin receptors, which in turn stimulates the release of growth hormone. 

Amazingly, MK677 achieves this without the expected side effect of disruption for other hormones like cortisol or testosterone.
