Can't speak for Pro Tools, but I have been running Logic X, MPC Daw, Ableton and stuff like Isotope Ozone together on a 2011 iMac with 8Gb, so I would expect the base MBP should be able to cope with it.
Much may depend on project sizes and if it was being wired into a full studio I think it would struggle, but I do a lot of hip-hop production from a home studio/workstation and don't have any issues.
