On the turn you have 6 outs to a straight or trips if nobody else has a king, so you need the pot to be 6.7 BB. It is 8.75 with more bets to come on the river so you can call.
If one of them has a king you split the pot with a J so you should count 4 outs, 2 jacks and 2 queens.
If you collect only one bet on the river you don't have the implied odds to call, you need the pot to be 10.5 to call with 4 outs.
If one of them has AQ, AA, or TT you have 4 outs as well. I'd say it's very likely MP1 has AA, AK, QQ, AQ or TT so you have 4 outs = fold, but not a big mistake to call the turn.
