Not total protection but definitely safer than without
While I would not pull out the grill with my bare hands on immediately opening the oven at 200°C, it is certainly less hot that the metal grill directly. Also, I did put one on my Cuisinart Toaster Oven grill and it works perfectly. Probably as long as the toaster oven is not set higher than the recommended heat, it works just like in the regular oven.
