## 🚀 快速开始
### 安装依赖
```bash
npm install
```
### 启动开发环境
```bash
npm run dev
```
### 生产环境
```bash
npm run build
npm run start:prod
```
### 其他命令
```bash
npm run dev:watch # nodemon 热重载
npm run dev:debug # 调试模式
npm start # 直接运行(ts-node)
```
## ⚙️ 配置
- 端口、名称、版本、日志、会话等均可通过环境变量配置,详见 `src/config/index.ts`
- 常用环境变量:
- `PORT`、`SERVER_NAME`、`SERVER_VERSION`、`NODE_ENV`、`LOG_LEVEL`、`MAX_SESSIONS`、`SESSION_TIMEOUT`
## 🔧 可用工具(API)
### 1. 天气查询 getWeather
- 参数:`city`(可选,城市名,缺省自动定位),`unit`(可选,celsius/fahrenheit)
- 示例:
```json
{ "city": "北京", "unit": "celsius" }
```
### 2. 定位 getLocation
- 参数:无
- 返回:当前定位的城市名(模拟/可扩展)
### 3. 数学计算 calculate
- 参数:`operation`(add/subtract/multiply/divide),`a`,`b`
- 示例:
```json
{ "operation": "add", "a": 1, "b": 2 }
```
### 4. IoT 设备控制 iotControl
- 参数:`deviceId`,`action`(lock/unlock/open/close/getStatus),`value`(可选)
- 示例:
```json
{ "deviceId": "lock001", "action": "lock" }
```
### 5. GitHub 搜索 search
- 参数:`query`(关键词),可选:`language`、`stars`、`forks`、`user`、`topic`、`created`、`sort`、`order`、`limit`
- 示例:
```json
{ "query": "nodejs", "language": "TypeScript", "limit": 3 }
```
## 📊 健康检查
- `GET /health` 返回服务器状态
## 🧪 测试
所有测试脚本位于 `test/` 目录:
- `test/test-mcp.js`、`test/test-modular.js`、`test/test-tools-rename.js`
- 运行示例:
```bash
node test/test-mcp.js
node test/test-modular.js
node test/test-tools-rename.js
```
## 🔄 扩展指引
- 新增工具:在 `src/tools/` 新建文件并注册
- 新增服务/中间件/类型:参考现有目录结构

# MCP Server - Modular Multi-Tool Service (English)
## 📝 Introduction
MCP Server is a modular backend based on Model Context Protocol (MCP), supporting weather, location, calculator, IoT device control, GitHub search and more. Ideal for AI agents and assistant scenarios.
## 📁 Structure
See above for directory tree. Main code in `src/`, tests in `test/`.
## 🚀 Quick Start
### Install dependencies
```bash
npm install
```
### Start development server
```bash
npm run dev
```
### Production
```bash
npm run build
npm run start:prod
```
### Other scripts
```bash
npm run dev:watch # nodemon hot reload
npm run dev:debug # debug mode
npm start # direct run (ts-node)
```
## ⚙️ Configuration
- All configs (port, name, version, log, session, etc.) via env vars, see `src/config/index.ts`
- Common env vars: `PORT`, `SERVER_NAME`, `SERVER_VERSION`, `NODE_ENV`, `LOG_LEVEL`, `MAX_SESSIONS`, `SESSION_TIMEOUT`
## 🔧 Tools (APIs)
### 1. Weather getWeather
- Params: `city` (optional, auto-location if omitted), `unit` (optional, celsius/fahrenheit)
- Example:
```json
{ "city": "Beijing", "unit": "celsius" }
```
### 2. Location getLocation
- Params: none
- Returns: current city (mocked/extendable)
### 3. Calculator calculate
- Params: `operation` (add/subtract/multiply/divide), `a`, `b`
- Example:
```json
{ "operation": "add", "a": 1, "b": 2 }
```
### 4. IoT Device Control iotControl
- Params: `deviceId`, `action` (lock/unlock/open/close/getStatus), `value` (optional)
- Example:
```json
{ "deviceId": "lock001", "action": "lock" }
```
### 5. GitHub Search search
- Params: `query` (keyword), optional: `language`, `stars`, `forks`, `user`, `topic`, `created`, `sort`, `order`, `limit`
- Example:
```json
{ "query": "nodejs", "language": "TypeScript", "limit": 3 }
```
## 📊 Health Check
- `GET /health` returns server status
## 🧪 Testing
All test scripts in `test/`:
- `test/test-mcp.js`, `test/test-modular.js`, `test/test-tools-rename.js`
- Run example:
```bash
node test/test-mcp.js
node test/test-modular.js
node test/test-tools-rename.js
```
## 🔄 Extension
- Add tool: create file in `src/tools/` and register
- Add service/middleware/type: follow existing structure
