What is the MCP server?
The MCP server is a middleware framework that allows developers to build intelligent agents that can interact with AI models (such as Google Gemini). It uses Server-Sent Events (SSE) technology to achieve real-time communication and has built-in multiple practical function modules.How to use the MCP server?
Interact with the server through the MCP client or direct API calls, send requests and receive responses from the AI model. Function calling and streaming responses are supported.Use cases
Suitable for application development that requires AI agent functions, such as intelligent assistants, knowledge Q&A systems, data analysis, and automated task processing.Main features
AI model integrationSeamlessly integrate large language models such as Google Gemini, supporting function calling and streaming responses
Real-time communicationRealize real-time data transmission based on Server-Sent Events (SSE)
Function modulesBuilt-in practical functions such as OpenWeatherMap weather query and BMI calculator
RAG supportSupport Retrieval Augmented Generation (RAG) function, and can integrate vector databases such as FAISS and ChromaDB
Advantages and limitations
Advantages
Simplify the development process of AI agents
Support multiple AI models and function modules
Provide real-time interaction capabilities
Flexible architecture design, easy to expand
Limitations
Requires a certain technical background to fully utilize all functions
Some advanced functions may require additional configuration
Dependent on external API services (such as OpenWeatherMap)
How to use
Start the MCP server
Run the server program and ensure that the necessary environment variables and API keys are configured
Connect to the MCP client
Use the MCP client or directly connect to the server through the API
Send a request
Send a request containing instructions to the server, such as weather query or BMI calculation
Receive a response
Get the output results of the AI model through the SSE stream or direct response
Usage examples
Weather queryGet real-time weather information by integrating the OpenWeatherMap API
Health consultationCalculate the BMI index and provide health advice
Knowledge Q&AKnowledge retrieval and answering based on RAG
