No. By definition, free/open-source software comes with a license that spells out under what conditions you can use/modify/distribute their code. As long as you obey the terms of the license, you don't need authors' permission.
Even the most restrictive free/open-source licenses allow the creation of new packages that build on the existing code. In MNE's case, my understanding is that it comes under the very liberal BSD license, which imposes no substantial restrictions; you would be even be permitted to incorporate it into proprietary commercial software.
