Commandos 1 and 2 would be a good first place to start. Shadow Tactics is a solid modern recreation of those two. They're more tactical stealth, rather than stealth action, but that's about as close as you're going to get while retaining the isometric viewpoint.
Otherwise try the first three Splinter Cell games, which don't have the isometric angle, but play the closest to MGS.
