Getting updated docs for LLMs

Unproofread notes

The Upstash team has launched Context7 which provides updated documentation for LLMs and AI code editors. They also have a MCP server that can be conveniently connected to code editors like Cursor, Windsurf, VS Code, Claude Code, Claude Desktop, etc.

On the homepage, I see more than 4,500 different libraries listed including all popular frameworks like Next.js, Laravel, Clerk, MongoDB, FastAPI, Supabase, etc. And clicking on any one of the libraries takes to a separate page for the library where docs are available as llms.txt or JSON formats.

Currently, it's free to use as I don't see any mentions of pricing anywhere. But they also have an API waitlist page where it's mentioned that:

The Context7 API is currently in private preview. Enter your email and we'll let you know as soon as it's live.

So there are chances that it will become paid, or at least some parts of it will be paid. I am perfectly okay to pay as long as it correctly does what it says.

I tried using it with Cursor and just mentioning "use context7" in the prompt itself triggers the tool and it does work. I am still testing it and will update soon.
