MCP Service Framework

What is MCP Service Framework?

MCP Service Framework is an extensible service framework based on the Model Context Protocol (MCP) that provides a standardized tool invocation interface and AI integration capabilities. It includes a basic service architecture, a weather service implementation example, and an intelligent conversation processing pipeline for developers building AI-powered applications.

How to use MCP Service Framework?

Install dependencies with npm install @modelcontextprotocol/sdk express dotenv, configure environment variables (e.g., DeepSeek API key, weather API key), and start the main service with npm run start:prod. Invoke the chat endpoint by sending a POST /chat request with a JSON body containing a message and optional sessionId.

• Complete MCP protocol Server/Client communication model
• Hot-pluggable service registration and invocation
• Context-aware conversation management with automatic tool calling
• Multi-turn dialogue state persistence
• Request retry mechanism (default 3 times)
• Unified error handling and service health monitoring

Use cases of MCP Service Framework

• Integrate AI assistants with real‑time weather data retrieval
• Build custom tool services that plug into an MCP-based conversation pipeline
• Create multi‑turn chatbots with context retention and dynamic tool selection
• Develop and test new MCP tools using the provided service template
