Context7 MCP - Up-to-date Docs for AI Agents

❌ 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LLMs rely on outdated or generic information about the libraries you use.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• ❌ Code examples are outdated and based on year-old training data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 MCP pulls up-to-date, version-specific documentation and code examples straight from the source — and gives them to your coding agent.

Add use context7 to your prompt (or set up a rule to auto-invoke):

Create a Next.js proxy 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 coding agent's context.

• 1️⃣ Write your prompt naturally
• 2️⃣ Tell the LLM to use context7 (or set up a rule once)
• 3️⃣ Get working code answers

No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.

Note This repository hosts the source code of Context7 MCP server. The supporting components — API backend, parsing engine, and crawling engine — are private and not part of this release.

📚 Adding Projects

Check out our project addition guide to learn how to add (or update) your favorite libraries to Context7.

🛠️ Installation

Requirements

• Node.js >= v20.18.1
• Cursor, Claude Code, VSCode, Devin Desktop or another MCP Client
• Context7 API Key (Optional) for higher rate limits and private repositories (Get yours by creating an account at context7.com/dashboard)

Tip Recommended Post-Setup: Add a Rule to Auto-Invoke Context7

After installing Context7 (see instructions below), enhance your workflow by adding a rule so you don't have to type use context7 in every prompt. Define a simple rule in your MCP client's rule section to automatically invoke Context7 on any code question:

• For Devin Desktop, in .devin/rules/ directory
• For Cursor, from Cursor Settings > Rules section
• For Claude Code, in CLAUDE.md file
• Or the equivalent in your MCP client

Example Rule:

Always use context7 when I need code generation, setup or configuration steps, or
library/API documentation. This means you should automatically use the Context7 MCP
tools to resolve library id and get library docs without me having to explicitly ask.

From then on, you'll get Context7's docs in any related conversation without typing anything extra. You can alter the rule to match your use cases.

Installing via Smithery

To install Context7 MCP Server for any client automatically via Smithery:

npx -y @smithery/cli@latest install @upstash/context7-mcp --client <CLIENT_NAME> --key <YOUR_SMITHERY_KEY>
