How do you keep track of MCPs, AI tools, and coding workflows?

I’ve been experimenting with MCPs, AI coding tools, and workflow rules across Cursor, Claude, Replit, Copilot, and Windsurf.

Discovery feels fragmented right now GitHub repos, docs, Reddit threads, HN comments, personal notes.

Curious how others here keep track of what exists and what’s actually useful. Do you rely on repos, newsletters, bookmarks, or something else?
