IE in Crafty, just cut/paste a FEN string directly into crafty, hit <enter>, then type "score" and it will give you the total score, and then king safety score (although the king safety score is only a 'partial score'). However, that is probably not the right way to tune, as in chess everything is relative to everything else. You don't want to shred your own king safety just to get a rook on the 7th or whatever..
