Move a point feature to a new location by specifying an xy

This seems like it should be a geoprocessing tool, but I can't seem to find one. What I'd like to do is modify an existing point feature by moving it to a new location based on an xy that I specify. Basically, I want to do what you can do in the edit tool in Arcmap with the "move to" command when you're editing a feature.

What I don't particularly want to do is create a new feature in the right place with the right attributes, but I'd do that as a last resort.

Anyone have any ideas?
