Narrative:
On ILS tower advised we would have helicopter traffic. We had the traffic in sight; however; he was climbing through our altitude as we were on short final. We received a traffic alert from TCAS and maintained visual contact. Tower questioned the traffic to make sure he would maintain visual separation with us. He then began to climb; as our paths eventually crossed with him being only 200 feet above us as we passed directly beneath him. We had very little lateral separation. I was prepared to execute a resolution advisory if needed. We landed safely without any other incident.ATC coordinated traffic far too close and to pass only 200 feet above us while we were on final approach. He requested that the helicopter pilot maintain visual separation; but he was too close and greatly reduced the margin for safety. Helicopter traffic should not be cleared into the approach corridor; especially when they are just above the approach path; which would have prevented us from doing a standard go-around if a resolution advisory would have been needed. It would have been a descending resolution with us being less than 1;000 feet AGL.
