## Description

Stop fighting with your AI agent's outdated knowledge of popular libraries. When you're building with a new framework or a specific version of a tool like Tailwind or Next.js, the standard training cutoff means your agent often suggests deprecated code or non-existent features. Context7 fixes this by giving your agent a direct line to the actual documentation. Instead of guessing, it pulls in specific Markdown chunks and real code examples based on the exact version you're using. It acts as a specialized knowledge layer that grounds every response in technical truth. You'll find it's a lot easier to build complex components when your agent actually knows the current rules. If you're looking to get this into your workflow, Vinkius is the best place to find and manage it. It makes the whole process of grounding your agent in real-time data a lot smoother.

## Tools

### resolve_library
Turns a fuzzy name like 'react' into a specific library ID and version. It ensures the agent looks at the right documentation source.

### query_docs
Fetches Markdown chunks and code examples for a specific library and topic. This provides the agent with the actual data it needs to answer your questions.

## Prompt Examples

**Prompt:** 
```
What's the new way to do layouts in Next.js 14?
```

**Response:** 
```
I've pulled the latest documentation for the Next.js 14 App Router. Here is how you should structure your layout and page files:

| File Type | Purpose |
| :--- | :--- |
| `layout.js` | Defines shared UI and metadata |
| `page.js` | Defines unique content |

**Example layout.js:**
```javascript
export default function Layout({ children }) {
  return <div>{children}</div>
}
```
This replaces the old pages directory approach.
```

**Prompt:** 
```
Show me a Tailwind v4 config example.
```

**Response:** 
```
Here is the configuration for the new Tailwind CSS v4 engine:

Tailwind v4 focuses on native CSS variables and a simplified configuration. You can now use the `@theme` block directly in your CSS:

```css
@theme {
  --color-primary: #3b82f6;
  --font-sans: 'Inter', sans-serif;
}
```
This version simplifies the config significantly compared to v3.
```

**Prompt:** 
```
Resolve 'react' for me.
```

**Response:** 
```
I've found several versions for 'react'. Here are the available IDs:

* **vercel/next.js/14.1.0** (latest)
* **vercel/next.js/13.5.6**
* **vercel/next.js/12.3.4**

Which version would you like to use for documentation?
```

## Capabilities

### Find exact library versions
Identify the correct library ID and version for any framework search query.

### Pull real code examples
Retrieve valid, version-specific code snippets directly into your development flow.

### Fetch specific documentation chunks
Get raw Markdown documentation for specific topics to ground your agent in facts.

### Stop hallucinations
Ensure your agent never suggests outdated API signatures or broken features.

### Bypass knowledge cutoffs
Access documentation synchronized with the latest releases instead of old training data.

## Use Cases

### Fixing outdated API suggestions
A dev asks for a Next.js 14 feature but gets Next.js 12 code. The agent uses resolve_library to find the 14.1.0 docs and query_docs to get the right answer.

### Exploring new frameworks
A prototype needs a specific Tailwind v4 component. The agent pulls the latest engine specs and code examples instantly.

### Verifying API signatures
A writer needs to check if a specific method exists in the current version of a library. The agent queries the live docs to confirm.

### Complex library integration
An engineer needs to know the exact layout for a specific library. The agent pulls the Markdown chunks to show the correct structure.

## Benefits

- Stop hallucinations by using query_docs to provide your agent with actual Markdown chunks from official sources. This ensures your agent stays grounded in the latest technical facts.
- Get accurate code by using resolve_library to ensure your agent isn't looking at outdated versions of a library. It helps you avoid breaking changes from previous releases.
- Save time on research because your agent pulls boilerplate and examples directly into your workspace. You won't have to tab out to search for common component structures anymore.
- Build faster with new frameworks since your agent stays updated with the latest releases, not just old training data. You get the most current patterns for every new project.
- Improve code quality by grounding every suggestion in the specific technical truths of the current API. It makes the difference between a guess and a production-ready snippet.

## How It Works

The bottom line is your agent gets access to live docs so it stops hallucinating old code.

1. Subscribe to the Connector and get your API key from the Context7 dashboard.
2. Connect your key to your preferred AI client like Cursor or Claude.
3. Ask your agent for specific documentation or code examples for any library.

## Frequently Asked Questions

**Does Context7 MCP help with outdated library info?**
Yes, it pulls live documentation directly into your chat. This means your agent stays up to date with the latest releases instead of relying on old training data.

**Can I use Context7 MCP for specific versions?**
Absolutely. It allows your agent to resolve a library name to a specific version ID, ensuring you get the exact documentation you need for your project.

**Does Context7 MCP work with Cursor?**
Yes, it works with any MCP-compatible client, including Cursor, Claude, and Windsurf. You just need to connect your API key.

**How does Context7 MCP stop hallucinations?**
It grounds your agent in technical truth. By pulling in real Markdown chunks and code examples, it prevents the agent from guessing or making up API signatures.

**Is Context7 MCP good for new frameworks?**
It's perfect for new frameworks. Because it pulls from live docs, your agent can help you prototype with the latest features as soon as they are released.

**Can Context7 MCP pull code examples?**
Yes, it retrieves specific code snippets and boilerplate for components or functions, so you can copy and paste them directly into your workspace.

**Can my agent find the latest documentation for a specific Tailwind CSS version?**
Yes. First, use the 'resolve_library' tool with 'tailwindcss'. It will return the deterministic ID and version (e.g., 'tailwindcss/3.4.1'). Then, use 'query_docs' to pull the exact Markdown blocks for your specific topic.

**Does Context7 provide code examples for the libraries I search for?**
Absolutely. When you query documentation via the 'query_docs' tool, the agent retrieves not only textual descriptions but also version-specific code examples found in the original library documentation to ensure implementation accuracy.

**How does this help prevent AI hallucinations in coding tasks?**
Standard LLMs have a training data cutoff. Context7 pulls live, version-specific documentation chunks that act as ground-truth context. By grounding your agent in this real-time data, it avoids hallucinating outdated or non-existent API methods.
