# Extract 50+ audio features
features = analyze_audio(audio_file, features=["rms", "spectral", "harmonic"])
```
### `export_visualization`
🆕 Professional audio visualization export with multiple formats
```python
# Generate waveforms, spectrograms, genre/quality charts

format="png",
color_scheme="cool"
)
# Returns base64-encoded image data
```

## 🚀 Quick Start
### Installation
```bash
# Clone the repository
git clone https://github.com/your-org/audio-agent-mcp.git
cd audio-agent-mcp
# Install dependencies
pip install -r requirements.txt
# Run tests to verify installation
pytest tests/ -v
```
### 🔐 API Key Setup (Required)
**All MCP server operations now require API key authentication** for security.
#### 1. Generate API Key
```bash
# Generate a secure API key
python generate_api_key.py --output-file .env.local
# Or generate for production
python generate_api_key.py --length 64 --output-file .env.production
```
#### 2. Set Environment Variable
```bash
# Set for current terminal session
export MCP_API_KEY="your-generated-api-key-here"
# Or add to your shell profile (~/.bashrc, ~/.zshrc)
echo 'export MCP_API_KEY="your-generated-api-key-here"' >> ~/.bashrc
source ~/.bashrc
```
#### 3. Verify API Key
```bash
# Test the API key
curl -H "Authorization: Bearer $MCP_API_KEY" \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' \
https://audio-agent-mcp.bretbouchard.dev/mcp
```
**Security Note**: Never commit API keys to version control. Use `.env.local` for development and environment variables in production.

"key": "C major",
"genre": {"genre": "electronic", "confidence": 0.87},
"quality": {"overall": 75.2, "clarity": 80.1}
}
```
**Example**: Optimize your audio setup
```python
# ChatGPT can optimize your hardware:
optimization = optimize_device(
device_id="focusrite_scarlett",
device_type="audio_interface",
usage_context="recording"
)
# Returns real optimization settings:
{
"buffer_size": 128,
