I want to start a discussion and maybe some brainstorming about the future of 3rd Party Metadata Agents. So far, the Custom Agents were loaded by Plex and integrated into the UI so that you can select them in your Library and be able to do basic tasks with them (like searching and fixing a match). …

Interesting questions. I am also interested in these things, but @McWanke told me that they don’t have plans to publish best-practice scripts for baisc things like authentication, so I get that the community needs to put all strings together in order to find solutions for these kind of problems.

I would hope that this is a separate Metadata Agent and is not specifically integrated into the existing Plex Series/Plex Movie A…
