```python
from chuk_mcp_server import tool, run

@tool
def add(a: int, b: int) -> int:
    """Add two numbers together."""
    return a + b

run()  # That's it! Server running on stdio
```

## ⚡ Quick Start

### Installation

```bash
# Basic installation
pip install chuk-mcp-server

# With optional features
pip install chuk-mcp-server[google_drive]  # Google Drive OAuth
```

### Your First Server (30 seconds)

**Option 1: Use the scaffolder** (recommended)
```bash
uvx chuk-mcp-server init my-server
cd my-server
uv run my-server
```

**Option 2: Write it yourself** (5 lines of code)
```python
from chuk_mcp_server import tool, run

@tool
def greet(name: str) -> str:
    """Greet someone by name."""
    return f"Hello, {name}!"

run()
```

**Option 3: Add to Claude Desktop** (instant integration)
```bash
uvx chuk-mcp-server init my-server --claude
# Automatically adds to claude_desktop_config.json
```

### Use with Claude Desktop

Add to `~/Library/Application Support/Claude/claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "my-server": {
      "command": "uv",
      "args": ["run", "my-server"]
    }
  }
}
```

Restart Claude Desktop - your tools are now available!

## 🚀 Why ChukMCPServer?

## 🎯 Core Features

### Decorators for Everything

```python
from chuk_mcp_server import tool, resource, prompt, requires_auth

@tool
def calculate(x: int, y: int) -> int:
    """Perform calculations."""
    return x + y

@resource("config://settings")
def get_settings() -> dict:
    """Access configuration."""
    return {"theme": "dark", "version": "1.0"}

@prompt
def code_review(code: str, language: str) -> str:
    """Generate code review prompt."""
    return f"Review this {language} code:\n{code}"

@tool
@requires_auth()
async def publish_post(content: str, _external_access_token: str | None = None) -> dict:
    """OAuth-protected tool."""
    # Token automatically injected and validated
    ...
```

### HTTP Mode for Web Apps

```python
from chuk_mcp_server import ChukMCPServer

mcp = ChukMCPServer("my-api")

@mcp.tool
async def process_data(data: str) -> dict:
    return {"processed": data}

mcp.run(host="0.0.0.0", port=8000)  # HTTP server
```

### Cloud Deployment (Auto-Detection)

```python
# Same code works everywhere - cloud platform auto-detected!
from chuk_mcp_server import tool, run

@tool
def my_tool(x: int) -> int:
    return x * 2

run()  # Automatically adapts to GCP, AWS, Azure, Vercel, etc.
```

### Server Composition (Mix Local & Remote Tools)

Combine multiple MCP servers into one unified interface. Import tools from local Python modules or remote servers (STDIO/HTTP/SSE):

```python
# config.yaml
composition:
  import:
    # Local Python module
    - name: "echo"
      type: "module"
      module: "chuk_mcp_echo.server:echo_service"
      prefix: "echo"

    # Remote MCP server via STDIO
    - name: "fetch"
      type: "stdio"
      command: "uvx"
      args: ["mcp-server-fetch"]
      prefix: "fetch"

    # Remote MCP server via HTTP
    - name: "weather"
      type: "http"
      url: "https://api.weather.com/mcp"
      prefix: "weather"
```

```python
from chuk_mcp_server import ChukMCPServer

mcp = ChukMCPServer("composed-server")
mcp.load_config("config.yaml")
mcp.run()  # All tools available under unified namespaces
```

**What you get:**
- ✅ **Module imports**: Direct Python imports (fastest)
- ✅ **STDIO proxy**: Connect to subprocess servers (uvx, npx, python -m)
- ✅ **HTTP proxy**: Connect to remote HTTP MCP servers
- ✅ **Built-in resilience**: Automatic timeouts, retries, circuit breakers (via chuk-tool-processor)
- ✅ **Unified namespace**: Tools prefixed by source (e.g., `fetch.fetch`, `echo.echo_text`)

## 🏆 Performance

ChukMCPServer is built for high throughput:

- **36,348 RPS** peak throughput (performance test)
- **39,261 RPS** with max optimizations (ultra test)
- **<3ms overhead** per tool call
- **100% success rate** under sustained load

See [Performance Benchmarks](https://chrishayuk.github.io/chuk-mcp-server/benchmarks) for detailed results.
