- **Multi-library Support**: Access documentation for any supported library

## 📦 Installation

### Option 1: Using AutoPM (Recommended)

```bash
# Install from npm with automatic configuration
autopm mcp install @upstash/context7-mcp --enable

# Configure API key
echo "CONTEXT7_API_KEY=your-key-here" >> .claude/.env

# Enable the server
autopm mcp enable context7

# Sync configuration
autopm mcp sync
```

## 🔑 Configuration

### Environment Variables

Add to `.claude/.env`:

```bash
# Optional: Minimum tokens for documentation retrieval (default: 10000)
DEFAULT_MINIMUM_TOKENS=10000
```

Note: Context7 API key is not required for basic usage.

## 🔧 Available Tools

### 1. `resolve-library-id`
Resolves a general library name into a Context7-compatible library ID.

**Example:**
```
Library: "react" → ID: "react/latest"
Library: "nextjs" → ID: "next/latest"
```

### 2. `get-library-docs`
Fetches documentation for a library using a Context7-compatible library ID.

**Parameters:**
- `libraryId` (required): Context7 library ID (e.g., "react/latest")
- `topic` (optional): Specific topic to focus on
- `tokens` (optional): Minimum tokens to retrieve (default: 10000)

**Example:**
```
get-library-docs("react/latest", topic="hooks")
get-library-docs("nextjs/14", topic="app-router", tokens=15000)
```
