```

## 🎯 Zero Configuration Quick Start

### Ultimate Zero Config (Magic Decorators)

```python
from chuk_mcp_server import tool, resource, run

# ✨ CLEAN: No server creation, no configuration needed!
@tool
async def hello(name: str = "World") -> str:
    """Say hello to someone (async)."""
    return f"Hello, {name}!"

@tool  
async def calculate(expression: str) -> str:
    """Calculate mathematical expressions (async)."""
    try:
        result = eval(expression)  # Note: Use safely in production
        return f"{expression} = {result}"
    except Exception as e:
        return f"Error: {str(e)}"

@resource("config://settings")
async def get_settings() -> dict:
    """Server configuration (async resource)."""
    return {
        "app": "Zero Config Demo",
        "version": "1.0.0",
        "magic": True,
        "performance_optimized": True
    }

if __name__ == "__main__":
    # ✨ CLEAN: Just run() - everything auto-detected!
    run()  # Auto-detects host, port, performance settings, everything!
```

### Traditional Style (Still Zero Config)

```python
from chuk_mcp_server import ChukMCPServer

# ✨ Smart server with auto-detected configuration
mcp = ChukMCPServer()  # Uses SmartConfig for all detection!

@mcp.tool
async def process_data(data: list, operation: str = "sum") -> dict:
    """Process data asynchronously."""
    if operation == "sum":
        result = sum(data) if all(isinstance(x, (int, float)) for x in data) else 0
    elif operation == "count":
        result = len(data)
    else:
        result = f"Unknown operation: {operation}"
    
    return {
        "operation": operation,
        "input_size": len(data),
        "result": result,
        "async": True
    }

@mcp.resource("docs://readme")  
async def get_readme() -> str:
    """Project documentation (async resource)."""
    return """# Zero Configuration MCP Server

This server was created with **ZERO** configuration!

## Performance Results
- MCP Ping: 39,651 RPS
- Async Tool Calls: 25,000+ RPS  
- Async Resource Reads: 26,000+ RPS
"""

if __name__ == "__main__":
    mcp.run()  # Auto-detects everything!
```

## 🔍 MCP Inspector Integration

ChukMCPServer works perfectly with [MCP Inspector](https://github.com/modelcontextprotocol/inspector):

1. **Start your server**:
   ```bash
   python zero_config_examples.py  # Runs on http://localhost:8000
   ```

2. **Use MCP Inspector**:
   - Transport Type: **Streamable HTTP**
   - URL: `http://localhost:8000/mcp`
   - All tools and resources will be automatically discovered

3. **For development with proxy**:
   ```bash
   # Use proxy on port 8011 for Inspector
   # URL: http://localhost:8011/mcp/inspector
   ```

## 🛠️ Advanced Features

### Type Safety and Parameter Conversion

```python
from typing import Union, List

@tool
async def smart_calculator(
    expression: str,
    precision: Union[str, int] = 2,
    format_output: bool = True
) -> str:
    """
    ChukMCPServer automatically handles:
    - String "2" → int 2
    - String "true" → bool True
    - JSON arrays → Python lists
    """
    # Your tool logic here
    pass
```

### Rich Resources with Multiple MIME Types

```python
@resource("docs://readme")
async def get_documentation() -> str:
    """🧠 Auto-inferred: mime_type=text/markdown"""
    return "# My API Documentation\n\nThis is **markdown** content!"

@resource("data://metrics")
async def get_metrics() -> dict:
    """🧠 Auto-inferred: mime_type=application/json"""
    return {
        "cpu_usage": 45.2,
        "memory_usage": 67.8,
        "requests_per_second": 39651  # Your actual performance!
    }
```

### Smart Environment Detection

```python
# Development mode (localhost:8000, debug=True, full logging)
NODE_ENV=development python server.py

# Production mode (0.0.0.0:PORT, debug=False, minimal logging)  
NODE_ENV=production python server.py

# Container mode (auto-detected from Docker/K8s environment)
# Automatically uses 0.0.0.0, optimizes for containers

# Serverless mode (auto-detected from AWS Lambda, Vercel, etc.)
# Automatically optimizes for cold starts and single workers
```

## 🚀 Examples

## 📋 API Reference

### Zero Config API

```python
from chuk_mcp_server import tool, resource, run

# Global decorators (ultimate simplicity)
@tool
async def hello(name: str) -> str:
    """Auto-inferred: category=general, tags=["tool", "general"]"""
    return f"Hello, {name}!"

@resource("config://settings")
async def get_settings() -> dict:
    """Auto-inferred: mime_type=application/json, tags=["resource", "config"]"""
    return {"app": "zero-config", "magic": True}

# Just run - everything auto-detected!
run()  # 🧠 Everything auto-detected using SmartConfig!
```

### Traditional API

```python
from chuk_mcp_server import ChukMCPServer

# Create server (all parameters optional - smart defaults used)
mcp = ChukMCPServer(
    name="My Server",        # Auto-detected from directory/package.json
    version="1.0.0", 
    host=None,               # Auto-detected (localhost/0.0.0.0)
    port=None,               # Auto-detected (finds available port)
    debug=None,              # Auto-detected (based on environment)
    tools=True,              # Enable tools capability
    resources=True,          # Enable resources capability
    prompts=False,           # Enable prompts capability
    logging=False            # Enable logging capability
)

# Decorators with smart inference
@mcp.tool                              # Auto-infers name, description, tags
@mcp.tool(tags=["custom"])            # Override smart defaults
@mcp.resource("uri://path")           # Auto-infers MIME type, tags
@mcp.endpoint("/path", methods=["GET"]) # Custom HTTP endpoint

# Manual registration
mcp.add_tool(tool_handler)
mcp.add_resource(resource_handler)

# Smart configuration access
mcp.get_smart_config()                # Get all smart configuration
mcp.get_smart_config_summary()        # Get detection summary
mcp.refresh_smart_config()            # Refresh configuration

# Run server with smart defaults
mcp.run()  # All parameters optional - uses smart detection
```

### Configuration Introspection

```python
# Get comprehensive smart configuration
smart_config = mcp.get_smart_config()
print(f"Environment: {smart_config['environment']}")
print(f"Workers: {smart_config['workers']}")
print(f"Performance Mode: {smart_config['performance_mode']}")

# Get detection summary
summary = mcp.get_smart_config_summary()
for key, value in summary["detection_summary"].items():
    print(f"{key}: {value}")

# Refresh configuration (useful for runtime changes)
mcp.refresh_smart_config()
```

```

### Docker

```dockerfile
FROM python:3.11-slim

WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt

COPY . .
EXPOSE 8000

# Zero config - automatically detects container environment
CMD ["python", "server.py"]
```

### Environment Variables (Optional)

```bash
# Override smart detection if needed
export NODE_ENV=production     # Force production mode
export PORT=8080              # Custom port
export DEBUG=false            # Override debug setting
export LOG_LEVEL=WARNING      # Custom log level

# Run with automatic optimization
python server.py
```

## 🔧 Configuration Options

### Performance Modes

```python
# Performance mode (39,000+ RPS)
python server.py --performance
# - LOG_LEVEL=WARNING (minimal logging)  
# - debug=False (no debug overhead)
# - Optimized for maximum throughput

# Development mode (full logging)
python server.py --development
# - Full logging enabled
# - debug=True (helpful for development) 
# - Still fast: 12,000+ RPS

# Smart auto-detection
python server.py

    port=9000,               # Override smart port detection  
    debug=False              # Override smart debug detection
)

# Or use smart defaults with manual run override
mcp = ChukMCPServer()        # All smart defaults
mcp.run(host="0.0.0.0", port=9000, debug=False)  # Runtime override
```
