Just highlighting this in case it was missed among other posts: there is an ongoing discussion about a possible future setup to integrate an MCP server and other AI-related APIs into Joplin, with support for plugins (which some of you may end up developing).
As mentioned there, implementing this architecture could itself be a solid GSoC project. If this topic interests you, feel free to submit a proposal around it!
