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LLMs rely on outdated or generic information about the libraries you use.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• Code examples are outdated and based on year-old training data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 prompt in Cursor:

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 fetches up-to-date code examples and documentation right into your LLM's context.

• 1 Write your prompt naturally
• 2 Tell the LLM to use context7
• 3 Get working code answers

No tab-switching, no hallucinated APIs that don't exist, no outdated code generations.
