Quick Start

Installation

# Install uv package manager
make install-uv

# Install all dependencies
make install

# Or install production only
make install-prod

Basic Usage

from mcp_server_hero import MCPServerHero
import anyio
from mcp.server.stdio import stdio_server

async def add_numbers(a: int, b: int) -> int:
    """Add two numbers together."""
    return a + b

async def main():
    # Create server instance
    server = MCPServerHero(name="My Server")
    
    # Register a tool
    server.add_tool(
        name="add",
        tool_func=add_numbers,
        description="Add two numbers",
        schema={
            "type": "object",
            "properties": {
                "a": {"type": "integer"},
                "b": {"type": "integer"}
            },
            "required": ["a", "b"]
        }
    )
    
    # Run the server
    async with stdio_server() as streams:
        await server.run(streams[0], streams[1], server.create_initialization_options())

if __name__ == "__main__":
    anyio.run(main)

Enterprise Usage

from mcp_server_hero import MCPServerHero
from mcp_server_hero.middleware.rate_limit import RateLimitMiddleware
from mcp_server_hero.auth.base import SimpleAuthProvider

# Create enterprise server
server = MCPServerHero("Enterprise Server", debug=True)

# Add advanced features
server.add_middleware(RateLimitMiddleware(tool_limit=100))
server.enable_auth_provider(SimpleAuthProvider())
await server.load_plugins_from_directory("plugins/")

# Initialize and run
await server.initialize()

Running Examples

# Run different server examples
make run-basic       # Basic function-based server
make run-advanced    # Class-based server with custom components  
make run-enterprise  # Full-featured enterprise server

# Run with different transports
make run-server      # SSE transport (web-based)
make run-stdio       # Stdio transport (direct communication)
make run-debug       # Debug mode with detailed logging

Development

# Code quality
make check          # Run all quality checks (lint + format + typecheck)
make test           # Run tests
make test-cov       # Run tests with coverage

# Individual quality checks  
make lint           # Code linting
make format         # Code formatting
make typecheck      # Type checking

Components

Tools

Tools perform actions and return results:

# Simple function tool
async def my_tool(param: str) -> str:
    return f"Result: {param}"

server.add_tool("my_tool", my_tool, "Description")

# Class-based tool with advanced features
from mcp_server_hero.tools.base import BaseTool

class MyTool(BaseTool):
    async def execute(self, arguments):
        return [TextContent(type="text", text="Result")]

Resources

Resources provide read-only data:

# Simple function resource
async def get_data() -> str:
    return "Resource data"

server.add_resource("data://example", get_data, "Example data")

Prompts

Prompts generate structured messages:

# Simple function prompt
async def create_prompt(topic: str) -> str:
    return f"Please explain {topic}"

server.add_prompt("explain", create_prompt, "Explanation prompt")

Middleware

Process requests through a pipeline:

from mcp_server_hero.middleware import ValidationMiddleware, TimingMiddleware

server.add_middleware(ValidationMiddleware())
server.add_middleware(TimingMiddleware())

Plugins

Extend functionality dynamically:

from mcp_server_hero.plugins.base import BasePlugin

class MyPlugin(BasePlugin):
    async def initialize(self, server):
        server.add_tool("plugin_tool", self.my_tool, "Plugin tool")

Configuration

from mcp_server_hero.config import ServerSettings

settings = ServerSettings(
    name="My Server",
    debug=True,
    log_level="DEBUG",
    timeout=60.0
)

server = MCPServerHero(settings=settings)

Monitoring & Metrics

The server provides comprehensive monitoring:

# Get server statistics
stats = server.get_server_stats()

# Get performance metrics  
metrics = await server.get_metrics()

# Health check
health = await server.health_check()

Project Commands

make help           # Show all available commands
make examples       # List example servers
make stats          # Show project statistics  
make clean          # Clean build artifacts
