Mo code:
[A] Fly—A lure constructed on a single-point hook, of feathers, tinsel, chenille, yarn, fur, hair, silk, rayon or nylon thread or floss, with or without spinner.
Artificial lure—A manufactured lure other than a fly or soft plastic bait (unscent-ed).
[C] Soft plastic bait (unscented)—Synthetic eggs, synthetic worms, synthetic grubs and soft plastic lures.
Per regulations your lure is a soft plastic bait.
Mo code further says:
From the closed zone 760 feet below Table Rock Dam to the mouth of Fall Creek, and tributaries of Lake Taneycomo. Artificial flies and lures only (soft plastics specifically prohibited).
Not that I see anything wrong with your lure. I would use it myself -- outside of the restricted zone.
