Intro

Context7 brings up-to-date, version-specific documentation and code examples directly into your AI coding assistant. That means no more outdated code or hallucinated APIs.

❌ Without Context7#

LLMs rely on outdated or generic information about the libraries you use:

• ❌ Code examples based on old training data
• ❌ Hallucinated APIs that 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 prompt in your AI coding assistant:

Create a Next.js middleware that checks for a valid JWT in cookies and redirects unauthenticated users to `/login`. use context7

Configure a Cloudflare Worker script to cache JSON API responses for five minutes. use context7

Context7 grounds your LLM with up-to-date documentation, ensuring that it always writes high quality code.

• 1️⃣ Write your prompt naturally
• 2️⃣ Add use context7 to your prompt
• 3️⃣ Get working code with current APIs

No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.
