Is MC allowable to run in a metal barn. The wire would be exposed. Will that give the wire protection to pass inspection?

Does this barn fall under 547? If yes than jacketed/PVC covered MC is allowed.

I find it hard to judge depending on details of "barn".
Standard (non-jacketed) MC is not an allowable wiring method for an Agricultural Building (Art 547), MC is not allowed where subject to physical damage or corrosive conditions (with exceptions), or in wet locations (subject to conditions).
If you can rule out the above, MC is fine.
