They don't know about the latest library updates.</p> <h2> The Solution: Context7 MCP Server </h2> <p><a href="https://context7mcp.com" rel="noopener noreferrer">Context7 MCP Server</a> solves this by providing <strong>real-time, version-specific documentation</strong> directly to your AI assistant. It supports over 9,000 libraries including React, Next.js, Vue, Django, FastAPI, and many more.</p> <h2> How It Works </h2> <p>Context7 uses the Model Context Protocol (MCP) to connect with your AI coding tool. When you ask about a library, Context7 fetches the current documentation and provides it to the AI, ensuring accurate code generation.</p> <h2> Quick Installation </h2> <p>Install in one command:<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code><span class="c"># For Cursor</span> npx @upstash/context7-mcp@latest init <span class="nt">--cursor</span> <span class="c"># For Claude Desktop</span> npx @upstash/context7-mcp@latest init <span class="nt">--claude</span> <span class="c"># For Windsurf</span> npx @upstash/context7-mcp@latest init <span class="nt">--windsurf</span> </code></pre> </div> <p>Then restart your editor.
