# Intro

> Context7 brings up-to-date, version-specific library documentation into your AI coding agent

Context7 brings up-to-date, version-specific documentation and code examples directly into your AI coding agent. That means no more outdated code or hallucinated APIs.

## ❌ Without Context7

LLMs rely on outdated or generic information about the libraries you use:

* ❌ Code examples based on 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 gives them to your coding agent.

Add `use context7` to your prompt in your coding agent:

```txt theme={null}
Create a Next.js proxy that checks for a valid JWT in cookies and redirects unauthenticated users to `/login`. use context7
```

```txt theme={null}
Configure a Cloudflare Worker script to cache JSON API responses for five minutes. use context7
```

Context7 grounds your coding agent with up-to-date documentation, ensuring that it always writes high quality code.

* 1️⃣ Write your prompt naturally
* 2️⃣ Add `use context7` to your prompt
* 3️⃣ Get working code with current APIs

No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.

Context7 is free to start: a free account includes 1,000 API calls each month, every public library, library owner tools, [Context7 Ask](https://context7.com/docs/ask/overview.md), and [Docs7](https://context7.com/docs/docs7/overview.md) for up to three sites. See [Plans & Pricing](https://context7.com/docs/plans-pricing.md).

## Get Started

Paste this prompt into your coding agent. The agent sets up Context7, and you sign in with OAuth in the browser. No API key is needed.

```txt theme={null}
Read https://context7.com/get-started.md and set up Context7
```

Or run `npx ctx7 setup` yourself. See [Installation](https://context7.com/docs/installation.md) for other ways to install.
