The 58-year-old's position is due to be reviewed later this year but he dismissed exit talk by insisting that he is in constant dialogue with the board about how to take the team forward.
"Genuinely, I have not had any discussion with Honda or McLaren about the future," Brawn told Autosport. "I am in discussion with Niki [Lauda] and the board about how we run the team in the future.
"The team has come a long way in the last 12 months, but we've got to make sure it keeps going the right way. Next year is very exciting with the new engine and I think this engineering group that's been put together under Bob Bell has still got more it can do.
"But we all need to understand our roles and make sure that we're all happy and motivated by them. But I'm not looking at going anywhere else."
Brawn remained as team principal at Mercedes after they bought out Brawn GP in 2009.
