You might be able to find 'Phineas and Ferb' rated M fanfiction on some larger fanfiction platforms. However, not all platforms allow this type of content. AO3 is one place to look. They have a wide range of fan - created works with different ratings. But you need to be cautious as the content may not always align with the original spirit of the show. Another option could be some dedicated Disney - related fanfiction communities, but they may have their own policies regarding mature content.

I'm not entirely sure as I haven't read all of the 'Phineas and Ferb' rated M fanfiction.

However, this kind of fanfiction may also deviate from the original positive and light - hearted spirit of the show.
Fanfiction.net could also be a place to search for 'Phineas and Isabella' rated M fanfiction. But be aware that the site has its own rules and regulations regarding content. Sometimes, the search function might not be perfect, so you may need to use some specific keywords related to the characters and the rating in different combinations to find what you're looking for.
