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-creatorRun with uvx (recommended)
uvx mcp-server-creatorRun as a module
python -m mcp_server_creatorFeatures
- 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)Available Tools

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())Development
