Context7 MCP - User Guide

What is this about?

This is the simple guide to Context7 MCP. It explains what it is good for, what to ask it, and when it is better than a normal AI answer.

Need the technical details instead? See the Context7 MCP Developer Guide.

1. What it helps with​

Context7 gives your AI assistant current documentation for libraries and frameworks.

That is useful when you want answers like:

  • "How do I configure this package?"
  • "What is the current API for this SDK?"
  • "How does auth work in the newest version?"

2. Good questions to ask​

Context7 is a strong choice for:

  • install and setup instructions,
  • framework configuration,
  • current API usage,
  • version-specific examples.

Typical prompts:

  • "Use Context7 and show the current Next.js auth setup."
  • "Get the latest docs for Supabase sign-up."
  • "How does this library configure middleware in version 14?"

3. When it is the right tool​

Use Context7 when the risk is outdated docs.

That usually means:

  • fast-moving JavaScript frameworks,
  • SDKs that changed recently,
  • tools where old examples break.

4. When not to use it​

Context7 is not the right tool for everything.

Do not expect it to:

  • debug a live browser,
  • read your GitHub issues and pull requests,
  • inspect your database,
  • understand your private codebase by itself.

5. Simple rule of thumb​

Choose Context7 if your question is basically:

"What do the current docs say?"

If the question is instead:

"What is happening in my app, repo, browser, or database right now?"

then another MCP is usually the better fit.
