# Context7 MCP Server

> Inject current library and framework documentation into AI context.

## Overview
Provides AI agents with up-to-date documentation for libraries and frameworks. Instead of relying on training data, Context7 fetches current documentation in real-time, preventing hallucinated APIs and outdated patterns.

```bash
npx -y @upstash/context7-mcp
