MCP Server Cookiecutter Template

MCP 服务 Cookiecutter 模板

用于使用 Python 创建 Model Context Protocol（MCP）服务的完整 Cookiecutter 模板。

什么是 MCP？

Model Context Protocol（MCP） 是一项开放标准，让应用以标准化的方式为 Claude 等大语言模型（LLM）提供上下文。MCP 服务可以公开：

• 工具：LLM 可执行以完成操作的函数
• 资源：LLM 可访问以获取上下文的数据源
• 提示词：可重复使用的 LLM 交互模板

功能

• 🚀 完整的项目结构，已预先配置所有必需组件
• 🔧 工具、资源和提示词的示例实现
• 📦 集成 FastMCP，支持简单的基于装饰器的开发
• 🧩 生命周期管理，可正确初始化和清理资源
• 🐍 现代 Python 实践，包含类型提示和文档
• 🛠️ 开发工具，包括 Makefile、测试和类型检查
• 🐋 支持 Docker，用于容器化部署
• 🔌 集成 Claude Desktop，可与 Claude 无缝测试

快速开始

要求

• Python 3.12+
• Cookiecutter

创建项目

# Install cookiecutter if needed
pip install cookiecutter

# Generate a new MCP server project from the template
cookiecutter gh:shubhamgupta-dat/mcp-server-cookiecutter

# Or from local copy
cookiecutter path/to/mcp-server-cookiecutter

开始使用新服务

# Navigate to your new project
cd your-project-name

# Set up the environment (uses uv under the hood)
make setup

# Activate the virtual environment
source .venv/bin/activate  # On Unix/MacOS
# or
.venv\Scripts\activate     # On Windows

# Run the server in development mode with the MCP Inspector
make dev

# Install the server in Claude Desktop (for local testing)
make install

## Overview

This is a Model Context Protocol (MCP) server that exposes tools, resources, and prompts for use with LLM applications like Claude. MCP servers let you extend AI applications with custom functionality, data sources, and templated interactions.

## Quick Start

### Setup with uv (Recommended)

```bash
# Set up the environment
make setup

# Activate the virtual environment
source .venv/bin/activate  # On Unix/MacOS
# or
.venv\Scripts\activate     # On Windows

# Run the server in development mode with the MCP Inspector
make dev

# Install the server in Claude Desktop
make install

手动设置

# Install uv if you don't have it
pip install uv

# Create a virtual environment
uv venv

# Activate the virtual environment
source .venv/bin/activate  # On Unix/MacOS
# or
.venv\Scripts\activate     # On Windows

# Install the package in development mode
uv pip install -e .

# Run in development mode
mcp dev {{cookiecutter.module_name}}.server

# Install in Claude Desktop
mcp install {{cookiecutter.module_name}}.server

Docker

使用 Docker 构建并运行：

# Build the Docker image
make docker-build
# or
docker build -t {{cookiecutter.project_name}} .

# Run the container
make docker-run
# or
docker run -p 8000:8000 {{cookiecutter.project_name}}

服务架构

服务由多个组件组成：

• server.py：MCP 服务的主要设置和配置
• config.py：配置管理
• tools/：工具实现（LLM 可执行的函数）
• resources/：资源实现（LLM 可访问的数据）
• prompts/：提示词模板实现（可重复使用的对话模板）

MCP 功能

此服务实现了全部三种 MCP 原语：

1. 工具：LLM 可调用以执行操作的函数

   • 示例：calculate、fetch_data、long_task

2. 资源：为 LLM 提供上下文的数据源

   • 示例：static://example、dynamic://{parameter}、config://{section}

3. 提示词：可重复使用的 LLM 交互模板

   • 示例：simple_prompt、structured_prompt、data_analysis_prompt

添加自己的组件

添加新工具

在 tools/ 目录中创建或修改文件：

@mcp.tool()
def my_custom_tool(param1: str, param2: int = 42) -> str:
    """
    A custom tool that does something useful.
    
    Args:
        param1: Description of first parameter
        param2: Description of second parameter with default value
        
    Returns:
        Description of the return value
    """
    # Your implementation here
    return f"Result: {param1}, {param2}"

添加新资源

在 resources/ 目录中创建或修改文件：

@mcp.resource("my-custom-resource://{param}")
def my_custom_resource(param: str) -> str:
    """
    A custom resource that provides useful data.
    
    Args:
        param: Description of the parameter
        
    Returns:
        The resource content
    """
    # Your implementation here
    return f"Resource content for: {param}"

添加新提示词

在 prompts/ 目录中创建或修改文件：

@mcp.prompt()
def my_custom_prompt(param: str) -> str:
    """
    A custom prompt template.
    
    Args:
        param: Description of the parameter
        
    Returns:
        The formatted prompt
    """
    return f"""
    # Custom Prompt Template
    
    Context: {param}
    
    Please respond with your analysis of the above context.
    """

配置

此服务支持通过以下方式进行配置：

1. 环境变量：使用 MCP_ 前缀（例如，MCP_API_KEY=xyz123）

   • 嵌套配置：使用双下划线（MCP_DATABASE__HOST=localhost）

2. 配置文件：通过 MCP_CONFIG_FILE 环境变量指定

配置示例：

{
  "api": {
    "key": "xyz123",
    "url": "https://api.example.com"
  },
  "database": {
    "host": "localhost",
    "port": 5432
  }
}
