Yes. I have seen individuals with <30 MCATs get into MSTPs (even at Top 5 ranked schools) in the past. (Before anyone asks: No, these were not underrepresented minority students.) The odds are stacked against you, but an applicant who is outstanding in every way except for MCATs does have a chance of getting into an MSTP. The lowest MCAT I have seen for an accepted student was a 23 for an individual that went to a NIH-funded MSTP at a state university.
However, you should be realistic about your chances and not overload your list of schools with those at the top of the rankings. It would be fair to contact schools and ask if they would even consider applicants with your MCAT score. They might even be willing to tell you what the lowest score has been of those admitted to their program in the last few years.
You do not make it clear what your situation is, but you should consider taking a year off to retake the MCAT. Some individuals improve their scores on a retake.
Good luck.
