About Mcp Demos
Mcp Demos is the example-code repository for the 《从原理到实战：掌握 MCP》 article series, illustrating how to build applications with MCP. It lists Node.js weather, Python filesystem, and client examples.
Key features
- 01MCP application examples
- 02Node.js weather server example
- 03Python filesystem server example
- 04Multi-connection client example
Use cases
- 01Study a weather MCP server implementation
- 02Reference a file operations server example
- 03See a client connect and list tools
MCP support
The repository includes MCP server and client examples, demonstrating weather and file operations, as well as connecting to multiple MCP servers and listing their available tools.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.
Details
From the project README《从原理到实战：掌握 MCP》系列文章的示例代码库
本仓库将在后续维护一系列使用 Model Context Protocol (MCP) 的示例项目，用于展示如何使用 MCP 协议构建应用程序。
项目列表
- weather-server-node: 官方示例，基于 Node.js 的天气服务 MCP 服务器，提供天气预报和天气警报功能。
- simple-filesystem-server-python: 基于 Python 的简易文件系统服务器，支持多种文件操作。
- mcp-client-demo: MCP 客户端示例，创建多个 MCP 连接并打印各服务器的可用工具。
通用安装步骤
每个子项目都有自己的安装和运行说明，请参阅各个项目目录中的 README.md 文件。

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
