Combine mayonnaise, egg, Dijon mustard, Worcestershire sauce, lemon juice, Old Bay seasoning, salt, and pepper in a mixing bowl.
Gently fold in the crab meat, breadcrumbs, and chopped parsley, mixing lightly to keep crab chunks intact.
Shape the mixture into small patties about 2 to 3 inches wide and place them on a tray.
Chill the patties in the refrigerator for 10 to 15 minutes to help them hold their shape.
Preheat the air fryer to 375°F (190°C).
Lightly spray the crab cakes with cooking spray or olive oil.
Air fry the crab cakes for 10 to 12 minutes, flipping halfway through, until golden and crispy.
Remove from the air fryer and serve hot with fresh lemon wedges.
