MCP Server Template (Python)

MCP Server Template (Python)

A ready-to-use template for building Model Context Protocol (MCP) servers in Python. This template helps you quickly create servers that can register and expose tools and prompts for AI models to use.

🚀 Quick Start

Prerequisites

• Python 3.10 or newer

Setup in 3 Easy Steps

1️⃣ Install the package

# Clone the repository
git clone https://github.com/nisarg38/mcp-server-template-python.git my-mcp-server
cd my-mcp-server

# Install in development mode
pip install -e ".[dev]"

2️⃣ Run your server

# Run with Python
python -m src.main

# Or use the convenient CLI
mcp-server-template

3️⃣ Your server is now live!

Access your MCP server at:

• 🌐 HTTP: http://localhost:8080
• 💻 Or use the stdio transport: mcp-server-template --transport stdio

You'll see log output confirming the server is running successfully.

🎮 Command Line Options

Customize your server behavior with these command-line options:

# Change port (default: 8080)
mcp-server-template --port 9000

# Enable debug mode for more detailed logs
mcp-server-template --debug

# Use stdio transport instead of HTTP
mcp-server-template --transport stdio

# Set logging level (options: debug, info, warning, error)
mcp-server-template --log-level debug

🛠️ Creating Your Own Tools and Prompts

Add a Tool

Tools are functions that AI models can call. To add a new tool:

1. Edit src/main.py
2. Add a new function with the @mcp.tool() decorator:

@mcp.tool()
def your_tool_name(param1: str, param2: int) -> Dict[str, Any]:
    """
    Your tool description - this will be shown to the AI.
    
    Args:
        param1: Description of first parameter
        param2: Description of second parameter
        
    Returns:
        Dictionary with your results
    """
    # Your tool logic here
    return {"result": "your result"}

Add a Prompt

Prompts are templates that AI models can access:

@mcp.prompt()
def your_prompt_name(param: str) -> str:
    """Your prompt description."""
    return f"""
    Your formatted prompt with {param} inserted.
    Use this for structured prompt templates.
    """

🚢 Deployment Options

Docker Deployment

# Build the Docker image
docker build -t my-mcp-server .

# Run the container
docker run -p 8080:8080 my-mcp-server

Cloud Deployment

This template is designed to work well with various cloud platforms:

• Deploy as a container on AWS, GCP, or Azure
• Run on serverless platforms that support containerized applications
• Works with Kubernetes for orchestration

🧪 Development Guide

# Install development dependencies
pip install -e ".[dev]"

# Run tests
pytest

# Format code
