+# SpringAI MCP RAG Project Documentation
+
+## Project Overview
+
+This project is an implementation of a Model Control Protocol (MCP) service based on SpringAI, featuring Retrieval-Augmented Generation (RAG) functionality. The project is divided into three main modules:
+
+1. **business-server** - Product information management service
+2. **mcp-client** - MCP client service with chat, search, and RAG capabilities
+3. **mcp-server** - MCP server service providing date and email tools
+
+## Features
+
+- Product information management (create, delete, query, update)
+- Chat functionality (supports streaming responses)
+- Web search functionality (integrated with SearXNG)
+- RAG functionality (supports document upload and retrieval)
+- Server-Sent Events (SSE) support
+- Email sending functionality
+- Date handling functionality
+
+## Technology Stack
+
+- Spring Boot 3.5.0
+- Spring AI
+- Model Context Protocol (MCP)
+- Redis (for chat memory storage)
+- PostgreSQL (for product information storage)
+- Reactor Netty (for reactive programming)
+- Lombok (to simplify Java code)
+- MapStruct (for object mapping)
+
+## Module Details
+
+### business-server
+
+Provides product information management services with the following core components:
+
+- `Product` entity class (JPA entity)
+- `ProductRepository` (JPA repository)
+- `ProductService` (business logic layer)
+- `ProductTool` (MCP tool implementation)
+
+### mcp-client
+
+MCP client service implementing the following features:
+
+- Chat functionality (Chat)
+- Web search (Internet Search)
+- RAG functionality (document upload and retrieval)
+- SSE (Server-Sent Events)
+- Frontend interface (built with Vue.js)
+
+### mcp-server
+
+MCP server service providing the following tools:
+
+- `DateTool` (retrieve current time)
+- `EmailTool` (email sending functionality)
+
+## Usage Instructions
+
+### Environment Preparation
+
+1. Java 17+
+2. Maven 3.x
+3. PostgreSQL database
+4. Redis server
+5. Python environment (for SearXNG search)
+
+### Configuration Instructions
+
+1. Modify `mcp-client/src/main/resources/application.yml` to set the SearXNG search service URL and result count
+2. Modify `mcp-server/src/main/resources/application.yml` to configure email server settings
+
+### Startup Steps
+
+1. Start the PostgreSQL database and create the required tables
+2. Start the Redis server
+3. Start the `mcp-server` module
+4. Start the `business-server` module
+5. Start the `mcp-client` module
+
+### API Documentation
+
+#### Product Management API
+
+- Create product: `POST /product`
+- Delete product: `DELETE /product/{productId}`
+- Query products: `GET /product`

+# SpringAI MCP RAG 项目文档
+
+## 项目概述
+
+本项目是一个基于SpringAI的Model Control Protocol (MCP) 服务实现，包含RAG（Retrieval-Augmented Generation）功能。项目分为三个主要模块：
+
+1. **business-server** - 商品信息管理服务
+2. **mcp-client** - MCP客户端服务，包含聊天、搜索和RAG功能
+3. **mcp-server** - MCP服务器服务，提供日期工具和邮件工具
+
+## 功能特性
+
+- 商品信息管理（创建、删除、查询、更新）
+- 聊天功能（支持流式响应）
+- 网络搜索功能（集成SearXNG）
+- RAG功能（支持文档上传和检索）
+- 服务器发送事件（SSE）支持
+- 邮件发送功能
+- 日期处理功能
+
+## 技术栈
+
+- Spring Boot 3.5.0
+- Spring AI
+- Model Context Protocol (MCP)
+- Redis（用于聊天记忆存储）
+- PostgreSQL（用于商品信息存储）
+- Reactor Netty（用于响应式编程）
+- Lombok（简化Java代码）
+- MapStruct（对象映射）
+
+## 模块说明
+
+### business-server
+
+提供商品信息管理服务，包含以下核心组件：
+
+- `Product` 实体类（JPA实体）
+- `ProductRepository`（JPA仓库）
+- `ProductService`（业务逻辑层）
