# Development Commands

## 🚀 Quick Start Commands

### 1. Install Dependencies
```bash
uv sync
```

### 2. Setup Environment
```bash
# Create .env file from template
cp .env.example .env

# Edit .env file and add your Anthropic API key
ANTHROPIC_API_KEY=your_actual_api_key_here
```

### 3. Run FastAPI Server
```bash
# Standard uvicorn command with auto-reload
uvicorn main:app --reload

# Or with custom host/port
uvicorn main:app --reload --host 0.0.0.0 --port 8000
```

### 4. Install MCP Server
```bash
# Install the MCP server for Claude Desktop
uv run mcp install mcp_main.py

# Or install from current directory
uv run mcp install .
```

### 5. Test MCP Server Locally
```bash
# Test the MCP server directly
python mcp_main.py

# Or using uv
uv run mcp_main.py
```

## 📊 API Testing

### Test FastAPI Endpoints
```bash
# Health check
curl http://localhost:8000/health

# Upload PDF
curl -X POST "http://localhost:8000/upload-pdf/" -F "file=@sample.pdf"

# List documents
curl http://localhost:8000/documents/

# Get document status
curl http://localhost:8000/status/{file_id}
```

## 🔧 Claude Desktop Configuration

### Manual Configuration
1. Open Claude Desktop configuration:
   - **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
   - **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
   - **Linux**: `~/.config/claude/claude_desktop_config.json`

2. Add the server configuration:
```json
{
  "mcpServers": {
    "pdf-parser": {
      "command": "uv",
      "args": ["--directory", "C:\\path\\to\\your\\pdf-parser", "run", "mcp_main.py"],
      "cwd": "C:\\path\\to\\your\\pdf-parser"
    }
  }
}
```

3. Restart Claude Desktop

## 🛠️ Development Tools

### Code Quality
```bash
# Format code
uv run ruff format .

# Lint code
uv run ruff check .

# Type checking
uv run mypy .
```

### Testing
```bash
# Run tests
uv run pytest

# Run with coverage
uv run pytest --cov=. --cov-report=html
```

## 🐛 Debugging

### Check Dependencies
```bash
python -c "import fitz, tiktoken, anthropic, fastapi, uvicorn, mcp; print('All dependencies OK')"
```

### Verbose Logging
```bash
# Run FastAPI with debug logging
uvicorn main:app --reload --log-level debug

# Run MCP server with debug
python mcp_main.py --verbose
```

### Environment Variables
```bash
# Check environment variables
python -c "import os; print('ANTHROPIC_API_KEY:', 'SET' if os.getenv('ANTHROPIC_API_KEY') else 'NOT SET')"
```

## 🔄 Common Workflows

### Development Workflow
1. `uv sync` - Install dependencies
2. `cp .env.example .env` - Setup environment
3. `uvicorn main:app --reload` - Start FastAPI server
4. `uv run mcp install mcp_main.py` - Install MCP server
5. Configure Claude Desktop
6. Test with PDF uploads

### Production Deployment
1. `uv sync --frozen` - Install exact dependencies
2. `uvicorn main:app --host 0.0.0.0 --port 8000` - Start production server
3. Configure reverse proxy (nginx/apache)
4. Setup SSL certificates
5. Configure Claude Desktop for production
