## 🛠️ Installation & Setup

### Step 1: Clone the Repository

```bash
git clone https://github.com/dannySubsense/youtube-mcp-server.git
cd youtube-mcp-server
```

### Step 2: Install Dependencies

```bash
pip install -r requirements.txt
```

### Step 3: Get YouTube API Key

1. Go to the [Google Cloud Console](https://console.cloud.google.com/)
2. Create a new project or select an existing one
3. Enable the YouTube Data API v3
4. Create credentials (API Key)
5. (Optional) Restrict the API key to YouTube Data API v3 for security

### Step 4: Configure API Key

Create a `credentials.yml` file in the project root:

```yaml
youtube_api_key: "YOUR_YOUTUBE_API_KEY_HERE"
```

**Important:** Never commit your `credentials.yml` file to version control!

### Step 5: Test the Server

```bash
python test_server.py
```

This will run comprehensive tests on all 14 functions to ensure everything is working correctly.

## 🔧 Integration Guides

### Claude Desktop Integration

1. **Install the server** following the setup steps above

2. **Add to Claude Desktop configuration** - Edit your Claude Desktop config file:

**Windows:** `%APPDATA%\Claude\claude_desktop_config.json`
**Mac:** `~/Library/Application Support/Claude/claude_desktop_config.json`

```json
{
  "mcpServers": {
    "youtube": {
      "command": "python",
      "args": ["/path/to/youtube-mcp-server/youtube_mcp_server.py"],
      "env": {
        "YOUTUBE_API_KEY": "your_youtube_api_key_here"
      }
    }
  }
}
```

3. **Restart Claude Desktop**

4. **Verify integration** - Ask Claude: "Can you search for Python tutorials on YouTube?"

### Cursor Integration

1. **Install the server** following the setup steps above

2. **Configure in Cursor settings:**

   - Open Cursor Settings
   - Navigate to MCP Servers
   - Add new server with the python command and arguments

3. **Set environment variable** for your API key

4. **Test with Cursor** by asking it to search YouTube content

### Custom Project Integration

For custom applications or other MCP clients:

```python
from youtube_mcp_server import (
    get_video_details,
    search_videos,
    evaluate_video_for_knowledge_base
)

# Example usage
async def example():
    # Search for videos
    results = await search_videos("machine learning", max_results=5)
    print(results)

    # Evaluate video for knowledge base
    evaluation = await evaluate_video_for_knowledge_base("dQw4w9WgXcQ")
    print(evaluation)
```

### Environment Variables Setup

You can also use environment variables instead of the credentials file:

```bash
export YOUTUBE_API_KEY="your_api_key_here"
```

## 📖 Usage Examples

### Basic Video Information

```python
# Get detailed video information
result = await get_video_details("https://www.youtube.com/watch?v=dQw4w9WgXcQ")

# Also works with video IDs
result = await get_video_details("dQw4w9WgXcQ")
```

### Search and Discovery

```python
# Search for recent Python tutorials
tutorials = await search_videos(
    query="Python tutorial",
    max_results=10,
    order="date"
)

# Get trending videos in the US
trending = await get_trending_videos(region_code="US", max_results=5)
```

### Channel Analysis

```python
# Get channel information
channel_info = await get_channel_details("@3Blue1Brown")

# Get recent videos from a channel
recent_videos = await get_channel_videos("@3Blue1Brown", max_results=5)

# Get all playlists from a channel
playlists = await get_channel_playlists("@3Blue1Brown")
```

### Content Evaluation (Special Feature)

```python
# Evaluate if a video is worth adding to knowledge base
# Includes technology freshness scoring for educational content
evaluation = await evaluate_video_for_knowledge_base("Z6nkEZyS9nA")

# Example output:
# 🟢 HIGHLY RECOMMENDED - Strong indicators of valuable content
# ⏰ Content Freshness: Very Recent (2 days old)
# 🚀 Tech Currency: React 2025 content - framework evolves rapidly
```

### Transcript Extraction (New!)
```python
# Extract full transcript content from a video
transcript = await get_video_transcript("Z6nkEZyS9nA")

# Also works with URLs and different languages
transcript_spanish = await get_video_transcript(
    "https://www.youtube.com/watch?v=Z6nkEZyS9nA", 
    language="es"
)

# Example output:
# 📝 Full Transcript: [Complete video transcript text]
# ⏰ Timestamped Segments: [00:15] Welcome to this tutorial...

```

### Engagement Analysis

```python
# Analyze video engagement metrics
engagement = await analyze_video_engagement("dQw4w9WgXcQ")

# Get video comments
comments = await get_video_comments("dQw4w9WgXcQ", max_results=10, order="relevance")
```
