## 🚀 Quick Start

### 1. Security Setup (REQUIRED)

```bash
# 1. Read the security guide
cat SECURITY_SETUP.md

# 2. Set up your Google service account (outside this repo)
# 3. Configure your environment variables
cp .env.template .env
# Edit .env with your actual values

# 4. Verify no sensitive files will be committed
git status
```

### 2. Installation

```bash
# Install dependencies
pip install -r requirements.txt

# Test the setup
python local_test.py
```

### 3. Choose Your Interface

#### 🤖 Fully Automated (Recommended)
```bash
# Start auto-processor - upload files and walk away!
python start_auto_processor.py
```

#### 🌐 API Server
```bash
# Start FastAPI server
python main.py
```

#### 🧠 LLM Integration (MCP)
```bash
# Start MCP server for Claude Desktop, etc.
python mcp_server.py
```

#### 🖥️ Command Line
```bash
# Manual dataset management
python dataset_manager.py list
python dataset_manager.py process YOUR_FILE_ID
```

## 🎯 Usage Scenarios

### Scenario 1: Set-and-Forget Automation
1. `python start_auto_processor.py`
2. Upload files to Google Drive
3. Files processed automatically within 30 seconds
4. Monitor with `python processor_dashboard.py --live`

### Scenario 2: LLM-Powered Data Analysis
1. Configure MCP server in Claude Desktop
2. Chat: "Analyze the dataset I just uploaded"
3. Claude uses MCP tools to process and explain your data

### Scenario 3: API Integration
1. `python main.py`
2. Integrate with your data pipelines via REST API
3. Programmatic dataset onboarding

```

## 🐳 Docker Deployment

```bash
# Build
docker build -t mcp-dataset-server .

# Run (mount your service account key securely)
docker run -p 8000:8000 \
  -v /secure/path/to/key.json:/app/keys/key.json \

  mcp-dataset-server
```

## 🔍 Troubleshooting

### Common Issues
- **No files detected**: Check Google Drive permissions
- **Processing errors**: Verify service account access
- **MCP not working**: Check Claude Desktop configuration

### Debug Commands
```bash
# Test Google Drive connection
python -c "from utils import get_drive_service; print('✅ Connected')"

# Check auto-processor status
python auto_processor.py --once

# Verify MCP server
python test_mcp_server.py
```
