MADRE and AHP+ are open source.
Both are licensed under Apache 2.0. In plain words: you can use, change and share them, including for commercial work, as long as you keep the license notice.
Apache 2.0
What it allows.
Use it for anything. In personal or commercial projects, without paying or asking permission.
Change it. You can modify the code and make your own version.
Share it. You can redistribute it, with or without changes.
With one condition. Include the license and the NOTICE file, and mark which files you changed.
The license also grants you rights to any patents that cover the code, and it comes without warranty of any kind. What it doesn’t include is the name or the logo: you can say your project uses MADRE, but not present it as if it were MADRE.
