You only need a valid San Marino passport at the border; immigration officers may still ask for a return or onward ticket, proof of accommodation and enough money for your stay. The 90-day limit usually counts calendar days from your arrival, so book your return flight inside that window.
Whatever your visa status, Montenegro applies the same entry conditions to every traveller:
Montenegro lets 98 passports in without a visa and requires an embassy visa from 100. San Marino citizens are treated the same way as Albania, Andorra, Austria, Belarus and Belgium. Overall the San Marino passport ranks #50 in the world with 102 visa-free destinations.

In the other direction, Montenegro citizens can visit San Marino visa-free for up to 30 days.
