Generate Python Code for MCP Servers

MCP Server Creator 🏗️

A powerful Model Context Protocol (MCP) server that creates other MCP servers! This meta-server provides tools for dynamically generating FastMCP server configurations and Python code.

🚀 Quick Start

Install with pip

pip install mcp-server-creator

Run with uvx (recommended)

uvx mcp-server-creator

Run as a module

python -m mcp_server_creator

Features

• Dynamic Server Creation: Create new MCP server configurations on the fly
• Tool Builder: Add custom tools with parameters, return types, and implementations
• Resource Manager: Add static and dynamic resources with template support
• Code Generation: Generate complete, runnable Python code for your servers
• File Export: Save generated servers directly to Python files
• Example Templates: Built-in example server to demonstrate capabilities

Usage

As an MCP Server

The MCP Server Creator is itself an MCP server that can be used with Claude Desktop or any MCP client.

Claude Desktop Configuration

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "mcp-server-creator": {
      "command": "uvx",
      "args": ["mcp-server-creator"]
    }
  }
}

Programmatic Usage

from mcp_server_creator import create_server, add_tool, generate_server_code

# Create a new server configuration
result = create_server(
    name="My API Server",
    description="A custom API integration server",
    version="1.0.0"
)

# Add a tool
add_tool(
    server_id="my_api_server",
    tool_name="fetch_data",
    description="Fetch data from the API",
    parameters=[{"name": "endpoint", "type": "str"}],
    return_type="dict",
    implementation='return {"data": f"Fetched from {endpoint}"}'
)

# Generate the code
code = generate_server_code("my_api_server")
print(code)

Example: Creating a Weather Service

import asyncio
from mcp_server_creator import create_server, add_tool, add_resource, save_server

async def create_weather_service():
    # Create the server
    create_server(
        name="Weather Service",
        description="Get weather information",
        version="1.0.0"
    )
    
    # Add a weather tool
    add_tool(
        server_id="weather_service",
        tool_name="get_weather",
        description="Get current weather for a city",
        parameters=[
            {"name": "city", "type": "str"},
            {"name": "units", "type": "str", "default": '"celsius"'}
        ],
        return_type="dict",
        is_async=True,
        implementation='''
    # Your weather API logic here
    return {
        "city": city,
        "temperature": 20,
        "units": units,
        "condition": "sunny"
    }'''
    )
    
    # Add a resource
    add_resource(
        server_id="weather_service",
        uri="weather://{city}/current",
        name="Current Weather",
        description="Get current weather data",
        is_template=True,
        implementation='return {"city": city, "weather": "sunny"}'
    )
    
    # Save to file
    await save_server("weather_service", "weather_service.py")

# Run the creation
asyncio.run(create_weather_service())
