There are no minimum requirements as such, but I wouldn't recomend running Mongo on the same box as your webserver.

MongoDB automatically uses all free memory on the machine as its cache
(http://docs.mongodb.org/manual/faq/fundamentals/#does-mongodb-require-a-lot-of-ram)

This, along with the reasons mentioned in this answer (albeit for RDBMS) makes running mongodb on a separate box (even a small one) a much better idea.
