MCP Factory

A factory framework focused on MCP server creation and management

🎯 Overview

MCP Factory is a lightweight MCP (Model Context Protocol) server creation factory. It focuses on simplifying the building, configuration and management process of MCP servers, enabling developers to quickly create and deploy MCP servers.

🌟 Key Features

• 🏭 Server Factory - Quickly create and configure MCP server instances
• 📁 Project Building - Automatically generate complete MCP project structure
• 🔧 Configuration Management - Flexible YAML configuration system
• 🔗 Server Mounting - Support multi-server mounting and management
• 🛠️ CLI Tools - Simple and easy-to-use command line interface
• 🔐 Permission Control - Scope-based access control with 4-level permission system
• ⚙️ Management Tools - FastMCP native methods exposed as server tools (20+ tools)
• 🛡️ Production Security - Automatic security validation and flexible authentication

🚀 Quick Start

Installation

pip install mcp-factory

Basic Usage

📋 Programmatic Mode

from mcp_factory import MCPFactory

factory = MCPFactory(workspace_root="./workspace")
config = {
    "server": {"name": "api-server", "description": "Dynamic API server"},
    "components": {
        "tools": [{"module": "greeting_tools", "enabled": True}]
    }
}
server_id = factory.create_server("api-server", config)

📄 Configuration File Mode

# config.yaml
server:
  name: file-server
  description: "Server from configuration file"

management:
  expose_management_tools: true
  enable_permission_check: true

auth:
  provider: "none"  # or "oauth" for OAuth2 flow

components:
  tools:
    - module: "file_tools"
      enabled: true

factory = MCPFactory(workspace_root="./workspace")
server_id = factory.create_server("file-server", "config.yaml")

🏗️ Project Mode

mcp-factory project create my-server

🚀 Direct Server Creation

from mcp_factory import ManagedServer

server = ManagedServer(name="direct-server")

@server.tool()
def calculate(x: float, y: float, operation: str) -> float:
    """Perform mathematical calculations"""
    return x + y if operation == "add" else x * y

server.run()

🎛️ Operation Modes

Mode	Best For	Key Features
📋 Dictionary	Enterprise Integration, Testing	Programmatic control, dynamic configuration
📄 Config File	DevOps, Team Collaboration	Environment-specific deployment, standardized templates
🏗️ Project	Professional Development	Complex applications, full security features

🛠️ CLI Usage

# Create new project
mcp-factory project create my-project

# Create shared component
mcp-factory config component create --type tools --name "auth_tools"

# Quick start temporary server
mcp-factory server quick

# Run server from config file or project name
mcp-factory server run config.yaml
mcp-factory server run my-project

# Run with custom transport
mcp-factory server run config.yaml --transport http --host 0.0.0.0 --port 8080

# Publish project to GitHub
mcp-factory project publish my-project

# List all servers
mcp-factory server list

🔐 Authentication Setup

JWT Authentication (via environment variables)

export FASTMCP_AUTH_BEARER_PUBLIC_KEY="-----BEGIN PUBLIC KEY-----..."
export FASTMCP_AUTH_BEARER_ISSUER="https://your-auth-server.com"
export FASTMCP_AUTH_BEARER_AUDIENCE="your-app-name"

OAuth2 Authentication (via configuration)

auth:
  provider: "oauth"
  oauth:
    issuer_url: "https://your-auth-server.com"
    client_id: "your-client-id"
    scopes: ["openid", "mcp:read", "mcp:write", "mcp:admin"]

Required Token Scopes:

• mcp:read - readonly management tools
• mcp:write - modify management tools
• mcp:admin - destructive management tools
• mcp:external - external system tools

🏗️ Architecture

Core Components

• MCPFactory - Main factory class supporting all operation modes
• ManagedServer - Server class with decorator-based tool registration
• Configuration System - Flexible YAML configuration management
• Project Builder - Automatic project structure generation

🔧 Management Tools System

Our servers automatically register 20+ management tools from FastMCP native methods with 4-level permission control:

Permission Levels: readonly → modify → destructive → external

Key Tools: manage_get_tools, manage_add_tool, manage_remove_tool, manage_mount, manage_import_server, etc.
