The Tigers have earned points against Bournemouth and Swansea in their last two games.
And McCann believes there are plenty of positives to take from the draw against last season’s play-off finalists.
He said: “I thought we defended well and limited them to shots from range. Any point away in the Championship is good regardless of who we play. So, we’ll take the point and move on.
“We limited them to very little, people will want to ask questions, people want to hit us when we’re down. We’re used to people having pops at us.
“We’ve been missing a lot of players and we’ve got guys coming back from injuries but we’ve got two clean sheets in a row with a back four that people say can’t defend in the Championship.
“Things take time, Rome wasn’t built in a day. We’ve got two points in a row; we can take a lot of positives defensively. It was the foundation for us to win the league last season.
“We know we have goals in the team when we’re fit and firing. They’re only going to get better.”
Tigers goalkeeper Matt Ingram made a string of first-half saves to deny the dominant hosts and secure another valuable point Hull.
Swansea ended with 70 per cent possession.
Swansea head coach Russell Martin’s side have only scored once at home in their opening three matches at the Swansea.com Stadium but he believes an end to their barren run is close.
He said: “I am frustrated for the players because I thought they were outstanding.
“We have limited a team to just one shot on target and that was in the 94th minute. We had complete dominance and control from our intensity and let’s get it right, they did not come here to defend. Their keeper has made some fantastic saves and we have had a few too many shots from outside the box but when teams defend that deep it becomes difficult.
“They did not come here to defend and sit back, we did that, we earned that, and the only frustration is we didn’t score.”
