Context7 MCP - Up-to-date Docs For Any Cursor Prompt
❌ Without Context7
LLMs rely on outdated or generic information about the libraries you use. You get:
- ❌ Code examples are outdated and based on year-old training data
- ❌ Hallucinated APIs don't even exist
- ❌ Generic answers for old package versions
✅ With Context7
Context7 MCP pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt.
Add use context7 to your question in Cursor:
How do I use the new Next.js `after` function? use context7
How do I invalidate a query in React Query? use context7
How do I protect a route with NextAuth? use context7
Context7 fetches up-to-date documentation and working code examples right into your LLM’s context.
- 1️⃣ Ask your question naturally
- 2️⃣ Tell the LLM to
use context7 - 3️⃣ Get working code answers
No tab-switching, no hallucinated APIs that don't exist, no outdated code generations.
