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LLMs rely on outdated or generic information about the libraries you use.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• ❌ Code examples are outdated and based on year-old training data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No tab-switching, no hallucinated APIs that don't exist, no outdated code generations.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

Agent Mode Configuration

If you're using Zed's agent mode, you need to enable this context server for your assistant:

1. Open Zed's assistant settings
2. Enable the Context7 MCP server. If you see that the status of the tool is a red dot, make sure you toggle it so that becomes green.
