Context7 MCP Server for Zed

This extension integrates Context7 as a Model Context Protocol (MCP) server for Zed’s Assistant, providing up-to-date documentation for any prompt.

What is Context7?

Context7 pulls up-to-date, version-specific documentation and code examples straight from the source and places them directly into your prompt context.

❌ 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LLMs rely on outdated or generic information about the libraries you use.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• ❌ Code examples are outdated and based on year-old training data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 that don’t even exist
• ❌ Generic answers for old package versions

✅ With Context7

Context7 fetches 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 Zed Assistant:

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

How It Works

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No tab-switching, no hallucinated APIs that don’t exist, no outdated code generations.

Installation

This extension can be installed from the Zed extension.
