How to get up-to-date API information for AI coding tools

The Rundown: Context7 MCP server eliminates AI hallucination by providing real-time API documentation and code examples directly to your AI coding tools like Windsurf and Cursor.

🧰 Who is this useful for:

  • Developers tired of outdated API examples from AI tools
  • Coders using Windsurf, Cursor, or similar AI assistants
  • Teams building projects with frequently updated libraries
  • Anyone wanting accurate, current documentation while coding


STEP 1: Access the Context7 Repository

Head over to the Context7 GitHub repository to grab the configuration code. The setup is straightforward, you'll find installation instructions specifically for different AI coding tools. Context7 maintains over 23,500 libraries with current versions of Next.js, React, Tailwind, and other popular frameworks.

Copy the configuration code provided for your specific tool.

STEP 2: Configure Your AI Coding Tool

Open your AI coding tool (Windsurf in this example) and navigate to the configuration settings. Look for "Configure" in the menu, then select "View Raw Config" to open your MCP configuration file.

This will open the mcp_config.json file where you'll paste the Context7 server configuration.

STEP 3: Install and Save Configuration

Paste the copied configuration code into your MCP config file. Save the file using Command+S (Mac) or Control+S (Windows).

Once saved, you'll see the Context7 MCP server appear as available, providing two key services: "Resolve Library ID" for finding libraries and "Get Library Docs" for accessing current documentation.

STEP 4: Start Using Up-to-Date API Information

Now you can prompt your AI coding tool with confidence. For example, try: "Create a simple Next.js project with OpenAI's API using GPT-4o model. Use context for up-to-date API call info."

The AI will automatically query Context7's database for the latest API documentation and provide accurate, current code examples instead of potentially outdated information.

Pro tip: Always mention "use context for up-to-date API info" in your prompts to make sure the AI uses the Context7 server for the most current documentation and examples.
