Building a new MCP? Testing one in development? Taking it to production?

Useful ones get shared in threads, people bookmark them, and then they become hard to find once the discussion moves on. To address that, I started keeping a public index of MCPs with real usage notes, where:

-reliable MCPs don’t get lost -setup quirks and limitations are documented -contributors are credited by name

AI-Stack.dev is where developers share MCPs at any stage and update the notes as they scale.

For MCP creators: → Post your alpha/beta MCP to get early user feedback → Update documentation as you fix bugs and add features → Let users find working MCPs, not just popular ones

For MCP users: → Find production-ready tools with real usage notes → See development-stage MCPs you can test and contribute to → Watch tools evolve from "works on my machine" to production-tested

If you’ve built or discovered an MCP that’s held up in real use, it can be added there.

Not trying to replace discussion here, just trying to preserve the useful stuff once the thread scrolls away.

I’ve been running into the same issue repeatedly when using Claude for coding: the model knows the concept, but the docs it references are slightly outdated or version-mismatched.

Context7 MCP seems to solve this by pulling documentation directly from official sources instead of relying on training data.

I’ve seen a lot of people mention it as one of the few MCPs that’s actually “always on” and worth the context cost — especially compared to search-based MCPs.

I started documenting MCPs (including Context7) with setup steps and usage notes so I don’t have to re-discover this every time.

Curious: - Are you using Context7 regularly? - Does it noticeably improve accuracy for you? - Any downsides you’ve run into?

(If helpful, I’ve written up the setup + notes here: https://ai-stack.dev)

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?
