remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

Integrations

Retrieves up-to-date documentation for Next.js features including the new after function and route protection with NextAuth
Supports Node.js as a runtime requirement (v18.0.0+) for the MCP server
Delivers up-to-date documentation and code examples for React library features

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LLMs rely on outdated or generic information about the libraries you use.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❌ Code examples are outdated and based on year-old training data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No tab-switching, no hallucinated APIs that don't exist, no outdated code generations.
