Recently, a developer used the Dify platform combined with MCP (Multi-Channel Protocol) technology to create an intelligent assistant that automatically sends weather information to friends via WeChat, greatly facilitating users' needs for weather forecasts. This article will provide you with a detailed introduction to the development process of this emerging application.
Firstly, the developer needs to set up an application called MCP Server in the Windows environment. To achieve this goal, the first step is to install a Python package named "uv", which is a fast project manager that helps users easily create and manage Python virtual environments. Users can quickly complete this operation with just a simple PowerShell command.
Next, the developer needs to use the open-source library wxauto to achieve automation of WeChat operations. The library depends on the PC version of WeChat and requires a WeChat version of 3.9.x or higher. After creating the project, the developer can write code to send WeChat messages through MCP Server. By calling relevant functions and inputting message content and the WeChat nickname of the recipient, the program can automatically complete the sending process.
In addition to the weather information sending function, the developer also created a weather retrieval MCP Server using the httpx library for network requests. Users only need to input the location they want to query, and the program will send a request to the weather service API and return real-time weather data. This function is not only efficient but also supports queries for weather conditions in multiple cities.
Finally, the developer used Dify to build an intelligent application, integrating the weather query and WeChat message sending functions. Users can get the weather conditions of a city simply by giving a voice command, and the information will be automatically sent to the specified friend. This integrated solution not only improves the user experience but also demonstrates the practical application of AI technology in daily life.
This case based on Dify's intelligent application not only makes weather information retrieval and sharing simpler but also demonstrates the great potential of the MCP protocol in reducing development costs and improving application efficiency.
