MCP Server Creator

What is MCP-Server-Creator?

MCP-Server-Creator is a meta-server built on the Model Context Protocol (MCP) that enables the dynamic creation and management of other MCP servers. It provides a framework for defining server configurations, tools, and resources, and then generating the corresponding Python code for these servers.

How to use MCP-Server-Creator?

Installation:

pip: pip install mcp-server-creator
uvx (recommended): uvx mcp-server-creator
As a module: python -m mcp_server_creator

Usage as an MCP Server: Integrate with MCP clients like Claude Desktop by adding the following to your claude_desktop_config.json:

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

Programmatic Usage (Python):

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)
