Context7 MCP - Up-to-date Code Docs For Any Prompt

❌ 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LLMs rely on outdated or generic information about the libraries you use.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• ❌ Code examples are outdated and based on year-old training data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 places them directly into your prompt.

Add use context7 to your prompt in Cursor:

Create a Next.js middleware 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 LLM's context.

• 1️⃣ Write your prompt 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No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.

🔨 Available Tools

Context7 MCP provides the following tools that LLMs can use:

• resolve-library-id: Resolves a general library name into a Context7-compatible library ID.

  • libraryName (required): The name of the library to search for

• get-library-docs: Fetches documentation for a library using a Context7-compatible library ID.

  • context7CompatibleLibraryID (required): Exact Context7-compatible library ID (e.g., /mongodb/docs, /vercel/next.js)
  • topic (optional): Focus the docs on a specific topic (e.g., "routing", "hooks")
  • tokens (optional, default 5000): Max number of tokens to return. Values less than 1000 are automatically increased to 1000.

🛟 Tips

Add a Rule

If you don't want to add use context7 to every prompt, you can define a simple rule in your MCP client's rule section:

• 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 to auto-invoke Context7 on any code question.

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.

Use Library Id

If you already know exactly which library you want to use, add its Context7 ID to your prompt. That way, Context7 MCP server can skip the library-matching step and directly continue with retrieving docs.

Implement basic authentication with Supabase. use library /supabase/supabase for API and docs.

The slash syntax tells the MCP tool exactly which library to load docs for.
