The midfielder insists they will only take stock of their position come January despite a positive start.
The Blues have lost just once in their opening eight games so far, at home to a then on fire Manchester City, a strong start given their struggles last season.
They beat champions Chelsea 3-1 in the most impressive of those performances so far, while they have also progressed in the Capital One cup, a marked improvement on the last campaign.
Roberto Martinez’s side can go fifth in the table if they beat West Brom on Monday evening but McCarthy insists they are not getting carried away.
“We are not getting carried away,” he told evertonfc.com.
“We had a tough start in terms of the games and we’ve got another tough few games coming up, so all we’re focused on is each game as it comes. Of course we want to build on the start we’ve had and we believe we can.”
Europe still the aim for Everton despite last season
The midfielder has also insisted that the side are determined to qualify for Europe again this season despite their struggles last year.
The Blues were highly impressive in their Europa League campaign, with two big wins against German side Wolfsburg in the group stages the pick of their victories during their run in the tournament.
It had a negative effect on their Premier League campaign though as they struggled to balance the added football from Europe, finishing a disappointing 11th in the table.
McCarthy though, says Europe is the aim but they will take stock in January.
“We want to achieve things at the club, get into European places, that’s the aim,” he added.
“Come January we can look again at the table and take stock then. There will still be a long way to go in the league but we can weigh up from there where we want to be going.”
