Context7

Gives the AI today's documentation, not last year's.

Why use Context7?

An AI model only knows the versions of software that existed when it was trained, so it confidently writes code for features that have since been renamed or removed. Context7 fetches the current documentation while the assistant is working. What it writes then matches the version you actually have installed.

When should you use Context7?

Working with software that changes quickly (web-building kits such as Next.js and Tailwind are the classic case), or with any tool released more recently than the model itself.

How do you install and use Context7?

  1. Add it to your assistant's connected tools with the command below.
  2. Add the words use context7 to your request, or set a rule so it happens every time.
  3. You get code written against current documentation instead of the model's memory.
Paste into the Terminal app claude mcp add context7 -- npx -y @upstash/context7-mcp
