You've got no limit for CLIMB, you've got no limit for MCT anything above these settings is considered a TOGA limit. (of course Climb may well equal MCT in some conditions)
FLEX is a variable feast that may give you a thrust above or below MCT - you can't normally tell, so wisdom and experience dictates that FLEX should be considered limited by the TOGA limits also.
Can't give you a FCOM reference but reading across from many other jet types this is likely to be true.
