I built an MCP-connected bookmark manager because X's are useless

I made BookmarkSOS because I had a dumb problem. I bookmark around 20-30 tweets a day on X, being threads, tools, launch posts, and design references. The problem? I would never go back, and if I did, I would never find what I needed again. X gives you a reverse-chronological list with no search, no folders, no tags. Basically a write-only database. Very disorganized and useless.

So I built a web app + extension that adds a save button to every tweet. One click captures everything that you need, text, images, videos, author, timestamps. All into a dashboard with folders, color-coded tags, and full-text search.

And the best part: it ships with an MCP server. You install it with command line, connect it to Claude Code, and now your AI can search and reference every tweet you've ever saved. "Find that thread about programmatic SEO I bookmarked last week" just works. Your bookmarks become part of your dev workflow instead of sitting in a graveyard.

Stack used: Next.js, Convex for the reactive backend, Better Auth with Google OAuth, and a Manifest V3 Chrome extension.

Would love to hear what you think.
