template-mcp-server

Okay, here's a PDM template structure and some key considerations for developing an MCP (Minecraft Protocol) server, translated into Chinese. I'll provide both the English and Chinese versions. **English Version (with explanations):** This template focuses on a modular and scalable approach. It's a starting point; you'll need to adapt it to your specific needs. ``` mcp_server/ ├── pyproject.toml # PDM configuration file ├── src/ │ ├── mcp_server/ # Main package directory │ │ ├── __init__.py # Makes 'mcp_server' a package │ │ ├── core/ # Core server logic │ │ │ ├── __init__.py │ │ │ ├── server.py # Main server class (handling connections, etc.) │ │ │ ├── client.py # Represents a connected client │ │ │ ├── protocol.py # Handles Minecraft protocol parsing/serialization │ │ │ └── event_loop.py # Asynchronous event loop management (if using asyncio) │ │ ├── networking/ # Networking related code │ │ │ ├── __init__.py │ │ │ ├── connection_handler.py # Handles new connections │ │ │ ├── packet_handler.py # Dispatches packets to appropriate handlers │ │ ├── modules/ # Optional: Modular features (e.g., chat, world management) │ │ │ ├── __init__.py │ │ │ ├── chat/ │ │ │ │ ├── __init__.py │ │ │ │ ├── chat_module.py │ │ │ ├── world/ │ │ │ │ ├── __init__.py │ │ │ │ ├── world_module.py │ │ ├── config/ # Configuration management │ │ │ ├── __init__.py │ │ │ ├── config.py # Loads and manages server configuration │ │ ├── utils/ # Utility functions │ │ │ ├── __init__.py │ │ │ ├── logger.py # Logging setup │ │ │ ├── data_structures.py # Custom data structures │ │ └── main.py # Entry point to start the server │ ├── tests/ # Unit tests │ │ ├── __init__.py │ │ ├── core/ │ │ │ ├── test_server.py │ │ │ ├── test_protocol.py │ ├── README.md # Project documentation │ └── LICENSE # License information ``` **Explanation of Key Components:** * **`pyproject.toml`:** PDM's configuration file. Defines dependencies, build settings, etc. Example: ```toml [project] name = "mcp_server" version = "0.1.0" description = "A Minecraft Protocol Server" authors = [{name = "Your Name", email = "your.email@example.com"}] dependencies = [ "cryptography", # For encryption (if needed) "asyncio", # For asynchronous operations (highly recommended) # Add other dependencies here ] [build-system] requires = ["pdm-backend"] build-backend = "pdm.backend" ``` * **`src/mcp_server/core/server.py`:** The heart of the server. Handles: * Socket creation and listening. * Accepting new client connections. * Managing client connections. * Server lifecycle (start, stop). * **`src/mcp_server/core/client.py`:** Represents a single connected Minecraft client. Handles: * Reading data from the client's socket. * Writing data to the client's socket. * Client authentication (login). * Client state (e.g., position, health). * **`src/mcp_server/core/protocol.py`:** Crucial for understanding and implementing the Minecraft protocol. Handles: * Packet parsing (converting raw bytes from the client into meaningful data). * Packet serialization (converting data into raw bytes to send to the client). * Protocol version handling (different Minecraft versions have different protocols). This is a *complex* area. You'll likely need to refer to the Minecraft protocol documentation (e.g., Wiki.vg). * **`src/mcp_server/networking/packet_handler.py`:** Receives parsed packets from `protocol.py` and dispatches them to the appropriate handlers (e.g., a chat handler for chat messages, a movement handler for player movement). * **`src/mcp_server/modules/`:** A place for optional features. This promotes modularity. For example, a chat module could handle chat messages, a world module could manage the game world. * **`src/mcp_server/config/config.py`:** Loads server configuration from a file (e.g., a JSON or YAML file). This allows you to easily change server settings without modifying the code. * **`src/mcp_server/utils/logger.py`:** Sets up logging for the server. Good logging is essential for debugging and monitoring. * **`src/mcp_server/main.py`:** The entry point of your server application. It typically: * Loads the server configuration. * Initializes the server. * Starts the server's main loop. **Key Considerations:** * **Asynchronous Programming (asyncio):** Minecraft servers need to handle many concurrent connections. Using `asyncio` is *highly* recommended for efficient handling of these connections. * **Minecraft Protocol:** The Minecraft protocol is complex and changes between versions. Refer to [https://wiki.vg/Protocol](https://wiki.vg/Protocol) for detailed information. Consider using a library that helps with protocol handling (though many are outdated). Be prepared to implement a significant portion of the protocol yourself. * **Security:** Implement proper security measures to prevent attacks (e.g., authentication, rate limiting, input validation). * **World Generation:** You'll need to implement world generation if you want a playable world. This is a complex topic in itself. * **Performance:** Optimize your code for performance. Profile your server to identify bottlenecks. * **Testing:** Write unit tests to ensure your code is working correctly. **Chinese Translation:** ``` mcp_server/ ├── pyproject.toml # PDM 配置文件 ├── src/ │ ├── mcp_server/ # 主包目录 │ │ ├── __init__.py # 使 'mcp_server' 成为一个包 │ │ ├── core/ # 核心服务器逻辑 │ │ │ ├── __init__.py │ │ │ ├── server.py # 主服务器类 (处理连接等) │ │ │ ├── client.py # 代表一个已连接的客户端 │ │ │ ├── protocol.py # 处理 Minecraft 协议的解析/序列化 │ │ │ └── event_loop.py # 异步事件循环管理 (如果使用 asyncio) │ │ ├── networking/ # 网络相关代码 │ │ │ ├── __init__.py │ │ │ ├── connection_handler.py # 处理新连接 │ │ │ ├── packet_handler.py # 将数据包分发到适当的处理程序 │ │ ├── modules/ # 可选: 模块化功能 (例如，聊天，世界管理) │ │ │ ├── __init__.py │ │ │ ├── chat/ │ │ │ │ ├── __init__.py │ │ │ │ ├── chat_module.py │ │ │ ├── world/ │ │ │ │ ├── __init__.py │ │ │ │ ├── world_module.py │ │ ├── config/ # 配置管理 │ │ │ ├── __init__.py │ │ │ ├── config.py # 加载和管理服务器配置 │ │ ├── utils/ # 实用函数 │ │ │ ├── __init__.py │ │ │ ├── logger.py # 日志设置 │ │ │ ├── data_structures.py # 自定义数据结构 │ │ └── main.py # 启动服务器的入口点 │ ├── tests/ # 单元测试 │ │ ├── __init__.py │ │ ├── core/ │ │ │ ├── test_server.py │ │ │ ├── test_protocol.py │ ├── README.md # 项目文档 │ └── LICENSE # 许可证信息 ``` **Chinese Explanation of Key Components (Simplified):** * **`pyproject.toml`:** PDM 的配置文件，定义依赖项、构建设置等。 * **`src/mcp_server/core/server.py`:** 服务器的核心，处理套接字创建、监听、客户端连接和服务器生命周期。 * **`src/mcp_server/core/client.py`:** 代表一个连接的 Minecraft 客户端，处理客户端数据的读取和写入、身份验证和客户端状态。 * **`src/mcp_server/core/protocol.py`:** 至关重要，用于理解和实现 Minecraft 协议。 处理数据包解析（将客户端的原始字节转换为有意义的数据）和数据包序列化（将数据转换为原始字节以发送到客户端）。 * **`src/mcp_server/networking/packet_handler.py`:** 接收来自 `protocol.py` 的已解析数据包，并将它们分发到适当的处理程序（例如，聊天消息的聊天处理程序，玩家移动的移动处理程序）。 * **`src/mcp_server/modules/`:** 可选功能的存放地，促进模块化。 * **`src/mcp_server/config/config.py`:** 从文件加载服务器配置，允许您轻松更改服务器设置，而无需修改代码。 * **`src/mcp_server/utils/logger.py`:** 设置服务器的日志记录。 良好的日志记录对于调试和监控至关重要。 * **`src/mcp_server/main.py`:** 服务器应用程序的入口点。 **Chinese Key Considerations:** * **异步编程 (asyncio):** Minecraft 服务器需要处理许多并发连接。 强烈建议使用 `asyncio` 来有效处理这些连接。 * **Minecraft 协议:** Minecraft 协议很复杂，并且在不同版本之间会发生变化。 请参阅 [https://wiki.vg/Protocol](https://wiki.vg/Protocol) 获取详细信息。 考虑使用一个帮助处理协议的库（尽管许多库已过时）。 准备好自己实现协议的很大一部分。 * **安全性:** 实施适当的安全措施以防止攻击（例如，身份验证、速率限制、输入验证）。 * **世界生成:** 如果您想要一个可玩的世界，您需要实现世界生成。 这本身就是一个复杂的话题。 * **性能:** 优化您的代码以提高性能。 分析您的服务器以识别瓶颈。 * **测试:** 编写单元测试以确保您的代码正常工作。 **Important Notes:** * This is a *template*. You'll need to fill in the details. * The Minecraft protocol is the most challenging part. Start with a simple version of the protocol and gradually add more features. * Consider using existing libraries for tasks like networking and data serialization, but be aware that many Minecraft-specific libraries are outdated. * Good luck! Developing an MCP server is a complex but rewarding project.
