This is the movement towards member of the triad, applicable to solids.

Compare to:

	Ágihoz megyek. I am going to(wards) Agi.
	Áginál vagyok. I am at/by (the house of, or stood by) Ági.
	Ágitól jöttem. I came from (the house of, or being next to) Ági.

Application of this case implies that an object is solid and that you are not (going towards/coming from) inside it.

This is often translated as "to" but this is can be unhelpful.  In terms of movement, it's better to think of it as "towards".
Hungarians don't say that they gave a present to their mother (using -hoz), they say that the gave a present for their moth (using -nak).
