Medical Council of India is the regulatory body for all Medical Colleges across India. So any Medical College should be recognised by MCI for accepting Students to its Medical Programmes. And if youhave completed your MBBS from any MCI recognised Medical Colleged, that itself has credibility. And it is valid across the world. But yes to practise in any other Country, you have to appear for the licensing exam of that particular country because the curriculum in India is slightly different to the curriculum of other countries.
