You get: - ❌ Code examples are outdated and based on year-old training data - ❌ Hallucinated APIs that don't even exist - ❌ Generic answers for old package versions ## ✅ With Context7 Context7 MCP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 places them directly into your prompt. Add `use context7` to your prompt (or [set up a rule](#️-installation) to auto-invoke): ```txt Create a Next.js middleware that checks for a valid JWT in cookies and redirects unauthenticated users to `/login`. use context7 ``` ```txt 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. - 1️⃣ Write your prompt naturally - 2️⃣ Tell the LLM to `use context7` (or [set up a rule](#️-installation) once) - 3️⃣ Get working code answers No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.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](https://context7.com/docs/adding-libraries) to learn how to add (or update) your favorite libraries to Context7. ## 🛠️ Installation ### Requirements - Node.js >= v18.0.0 - Cursor, Claude Code, VSCode, Windsurf 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](https://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 Windsurf, in `.windsurfrules` file > - For Cursor, from `Cursor Settings > Rules` section > - For Claude Code, in `CLAUDE.md` file > - Or the equivalent in your MCP client > > **Example Rule:** > > ```txt > Always use context7 when I need code generation, setup or configuration steps, or > library/API docum
