mcpserver-ts

Here's a basic MCP (Mock Control Panel) server template in TypeScript for quick mock data, along with explanations and considerations: ```typescript // server.ts import express, { Request, Response } from 'express'; import cors from 'cors'; // Import the cors middleware import bodyParser from 'body-parser'; const app = express(); const port = process.env.PORT || 3000; // Enable CORS for all origins (for development - adjust for production!) app.use(cors()); // Parse JSON request bodies app.use(bodyParser.json()); // Mock Data (Replace with your actual mock data) const mockData = { users: [ { id: 1, name: 'John Doe', email: 'john.doe@example.com' }, { id: 2, name: 'Jane Smith', email: 'jane.smith@example.com' }, ], products: [ { id: 'p1', name: 'Awesome Widget', price: 29.99 }, { id: 'p2', name: 'Deluxe Gadget', price: 49.99 }, ], settings: { theme: 'dark', notificationsEnabled: true, }, }; // API Endpoints app.get('/api/users', (req: Request, res: Response) => { res.json(mockData.users); }); app.get('/api/users/:id', (req: Request, res: Response) => { const userId = parseInt(req.params.id); const user = mockData.users.find((u) => u.id === userId); if (user) { res.json(user); } else { res.status(404).json({ error: 'User not found' }); } }); app.get('/api/products', (req: Request, res: Response) => { res.json(mockData.products); }); app.get('/api/settings', (req: Request, res: Response) => { res.json(mockData.settings); }); app.put('/api/settings', (req: Request, res: Response) => { // In a real MCP, you'd validate and update the settings. // For this mock, we'll just echo back what we received. mockData.settings = req.body; // WARNING: No validation! res.json(mockData.settings); }); // Start the server app.listen(port, () => { console.log(`Mock MCP Server listening at http://localhost:${port}`); }); ``` Key improvements and explanations: * **TypeScript:** Uses TypeScript for type safety and better code organization. Install the necessary dev dependencies: `npm install --save-dev typescript @types/node @types/express` and `npm install express cors body-parser`. You'll also need to configure a `tsconfig.json` file (see below). * **Express:** Uses Express.js, a popular Node.js web framework, for routing and handling HTTP requests. * **CORS:** Includes `cors` middleware. **Crucially important** for allowing your frontend (running on a different port, e.g., `localhost:4200`) to access the API. In production, you'll want to restrict the allowed origins to your actual domain. * **Body Parser:** Uses `body-parser` middleware to parse JSON request bodies (needed for `PUT` requests, for example). * **Mock Data:** Provides a simple `mockData` object. This is where you'll define the data that your API endpoints will return. Replace this with your specific mock data. * **API Endpoints:** * `/api/users`: Returns a list of users. * `/api/users/:id`: Returns a specific user by ID. * `/api/products`: Returns a list of products. * `/api/settings`: Returns the settings. * `/api/settings` (PUT): Simulates updating settings. **Important:** This version *does not* validate the incoming data. In a real application, you *must* validate the data before updating your mock data. * **Error Handling:** Includes a basic 404 error for when a user is not found. * **Port Configuration:** Uses `process.env.PORT` to allow you to configure the port via an environment variable (useful for deployment). Defaults to 3000. * **Clear Comments:** Explains the purpose of each section of the code. **How to use it:** 1. **Create a Project:** ```bash mkdir mock-mcp cd mock-mcp npm init -y npm install express cors body-parser npm install --save-dev typescript @types/node @types/express ts-node nodemon ``` 2. **Create `server.ts`:** Copy and paste the code above into a file named `server.ts`. 3. **Create `tsconfig.json`:** This file tells the TypeScript compiler how to compile your code. A basic `tsconfig.json` looks like this: ```json { "compilerOptions": { "target": "es6", "module": "commonjs", "outDir": "./dist", "esModuleInterop": true, "forceConsistentCasingInFileNames": true, "strict": true, "skipLibCheck": true, "resolveJsonModule": true }, "include": ["./server.ts"], "exclude": ["node_modules"] } ``` 4. **Add a `start` script to `package.json`:** This makes it easy to run your server. Add or modify the `scripts` section of your `package.json` to include: ```json "scripts": { "start": "node dist/server.js", "dev": "nodemon server.ts", "build": "tsc" } ``` 5. **Build and Run:** ```bash npm run build # Compile the TypeScript code npm start # Run the compiled JavaScript code ``` Alternatively, use the `dev` script with `nodemon` for automatic restarts on code changes: ```bash npm run dev ``` **Important Considerations:** * **Data Validation:** The `PUT /api/settings` endpoint *does not* validate the incoming data. This is a **critical security risk** in a real application. You should always validate data before using it. Libraries like `joi` or `yup` can help with this. * **Error Handling:** The error handling is very basic. You should add more robust error handling, including logging and more informative error messages. * **Authentication/Authorization:** This mock server has no authentication or authorization. In a real MCP, you would need to implement these to protect your data. * **Database:** This mock server uses in-memory data. For a more realistic MCP, you would likely use a database (e.g., MongoDB, PostgreSQL). * **Scalability:** This is a very simple server. For a production MCP, you would need to consider scalability and performance. * **CORS Configuration (Production):** In production, you *must* configure CORS to only allow requests from your specific domain(s). Do *not* use `cors({ origin: '*' })` in production. Instead, specify the allowed origins: ```typescript app.use(cors({ origin: 'https://your-frontend-domain.com' // Replace with your actual domain })); ``` * **Nodemon Configuration:** You might need a `nodemon.json` file to configure nodemon to watch for changes in your TypeScript files and restart the server. A basic `nodemon.json` would look like this: ```json { "watch": ["server.ts"], "ext": "ts", "exec": "ts-node ./server.ts" } ``` **Example `package.json` (after adding scripts):** ```json { "name": "mock-mcp", "version": "1.0.0", "description": "A mock MCP server", "main": "index.js", "scripts": { "start": "node dist/server.js", "dev": "nodemon server.ts", "build": "tsc" }, "keywords": [], "author": "", "license": "ISC", "dependencies": { "body-parser": "^1.20.4", "cors": "^2.8.5", "express": "^4.18.2" }, "devDependencies": { "@types/express": "^4.17.21", "@types/node": "^20.11.20", "nodemon": "^3.1.0", "ts-node": "^10.9.2", "typescript": "^5.4.2" } } ``` This template provides a solid foundation for building a mock MCP server. Remember to adapt it to your specific needs and add the necessary features for your project. Good luck! ```chinese 这是一个用 TypeScript 编写的 MCP（Mock Control Panel，模拟控制面板）服务器模板，用于快速生成模拟数据，并附带解释和注意事项： ```typescript // server.ts import express, { Request, Response } from 'express'; import cors from 'cors'; // 导入 cors 中间件 import bodyParser from 'body-parser'; const app = express(); const port = process.env.PORT || 3000; // 启用 CORS 以允许所有来源（用于开发 - 生产环境需要调整！） app.use(cors()); // 解析 JSON 请求体 app.use(bodyParser.json()); // 模拟数据（替换为你的实际模拟数据） const mockData = { users: [ { id: 1, name: 'John Doe', email: 'john.doe@example.com' }, { id: 2, name: 'Jane Smith', email: 'jane.smith@example.com' }, ], products: [ { id: 'p1', name: 'Awesome Widget', price: 29.99 }, { id: 'p2', name: 'Deluxe Gadget', price: 49.99 }, ], settings: { theme: 'dark', notificationsEnabled: true, }, }; // API 端点 app.get('/api/users', (req: Request, res: Response) => { res.json(mockData.users); }); app.get('/api/users/:id', (req: Request, res: Response) => { const userId = parseInt(req.params.id); const user = mockData.users.find((u) => u.id === userId); if (user) { res.json(user); } else { res.status(404).json({ error: 'User not found' }); } }); app.get('/api/products', (req: Request, res: Response) => { res.json(mockData.products); }); app.get('/api/settings', (req: Request, res: Response) => { res.json(mockData.settings); }); app.put('/api/settings', (req: Request, res: Response) => { // 在真实的 MCP 中，你需要验证和更新设置。 // 对于这个模拟，我们只是将收到的内容回显。 mockData.settings = req.body; // 警告：没有验证！ res.json(mockData.settings); }); // 启动服务器 app.listen(port, () => { console.log(`Mock MCP Server listening at http://localhost:${port}`); }); ``` 关键改进和解释： * **TypeScript:** 使用 TypeScript 提高类型安全性和代码组织性。 安装必要的开发依赖项：`npm install --save-dev typescript @types/node @types/express` 和 `npm install express cors body-parser`。 你还需要配置一个 `tsconfig.json` 文件（见下文）。 * **Express:** 使用 Express.js，一个流行的 Node.js Web 框架，用于路由和处理 HTTP 请求。 * **CORS:** 包含 `cors` 中间件。 **至关重要**，用于允许你的前端（运行在不同的端口，例如 `localhost:4200`）访问 API。 在生产环境中，你需要将允许的来源限制为你的实际域名。 * **Body Parser:** 使用 `body-parser` 中间件来解析 JSON 请求体（例如，`PUT` 请求需要）。 * **模拟数据:** 提供一个简单的 `mockData` 对象。 你可以在这里定义你的 API 端点将返回的数据。 将其替换为你的特定模拟数据。 * **API 端点:** * `/api/users`: 返回用户列表。 * `/api/users/:id`: 返回指定 ID 的用户。 * `/api/products`: 返回产品列表。 * `/api/settings`: 返回设置。 * `/api/settings` (PUT): 模拟更新设置。 **重要提示：** 此版本*不*验证传入的数据。 在实际应用中，你*必须*在更新模拟数据之前验证数据。 * **错误处理:** 包含一个基本的 404 错误，用于在找不到用户时返回。 * **端口配置:** 使用 `process.env.PORT` 允许你通过环境变量配置端口（对部署很有用）。 默认为 3000。 * **清晰的注释:** 解释了代码每个部分的目的。 **如何使用它：** 1. **创建项目：** ```bash mkdir mock-mcp cd mock-mcp npm init -y npm install express cors body-parser npm install --save-dev typescript @types/node @types/express ts-node nodemon ``` 2. **创建 `server.ts`：** 将上面的代码复制并粘贴到名为 `server.ts` 的文件中。 3. **创建 `tsconfig.json`：** 此文件告诉 TypeScript 编译器如何编译你的代码。 一个基本的 `tsconfig.json` 如下所示： ```json { "compilerOptions": { "target": "es6", "module": "commonjs", "outDir": "./dist", "esModuleInterop": true, "forceConsistentCasingInFileNames": true, "strict": true, "skipLibCheck": true, "resolveJsonModule": true }, "include": ["./server.ts"], "exclude": ["node_modules"] } ``` 4. **将 `start` 脚本添加到 `package.json`：** 这可以让你轻松运行服务器。 添加或修改 `package.json` 的 `scripts` 部分，使其包含： ```json "scripts": { "start": "node dist/server.js", "dev": "nodemon server.ts", "build": "tsc" } ``` 5. **构建和运行：** ```bash npm run build # 编译 TypeScript 代码 npm start # 运行编译后的 JavaScript 代码 ``` 或者，使用带有 `nodemon` 的 `dev` 脚本，以便在代码更改时自动重启服务器： ```bash npm run dev ``` **重要注意事项：** * **数据验证：** `PUT /api/settings` 端点*不*验证传入的数据。 在实际应用中，这是一个**严重的安全风险**。 你应该始终在使用数据之前验证数据。 诸如 `joi` 或 `yup` 之类的库可以帮助你完成此操作。 * **错误处理：** 错误处理非常基础。 你应该添加更强大的错误处理，包括日志记录和更具信息性的错误消息。 * **身份验证/授权：** 此模拟服务器没有身份验证或授权。 在真实的 MCP 中，你需要实现这些来保护你的数据。 * **数据库：** 此模拟服务器使用内存中的数据。 对于更真实的 MCP，你可能会使用数据库（例如，MongoDB、PostgreSQL）。 * **可扩展性：** 这是一个非常简单的服务器。 对于生产 MCP，你需要考虑可扩展性和性能。 * **CORS 配置（生产环境）：** 在生产环境中，你*必须*配置 CORS 以仅允许来自你的特定域的请求。 *不要*在生产环境中使用 `cors({ origin: '*' })`。 而是指定允许的来源： ```typescript app.use(cors({ origin: 'https://your-frontend-domain.com' // 替换为你的实际域名 })); ``` * **Nodemon 配置：** 你可能需要一个 `nodemon.json` 文件来配置 nodemon 以监视 TypeScript 文件中的更改并重新启动服务器。 一个基本的 `nodemon.json` 如下所示： ```json { "watch": ["server.ts"], "ext": "ts", "exec": "ts-node ./server.ts" } ``` **示例 `package.json`（添加脚本后）：** ```json { "name": "mock-mcp", "version": "1.0.0", "description": "A mock MCP server", "main": "index.js", "scripts": { "start": "node dist/server.js", "dev": "nodemon server.ts", "build": "tsc" }, "keywords": [], "author": "", "license": "ISC", "dependencies": { "body-parser": "^1.20.4", "cors": "^2.8.5", "express": "^4.18.2" }, "devDependencies": { "@types/express": "^4.17.21", "@types/node": "^20.11.20", "nodemon": "^3.1.0", "ts-node": "^10.9.2", "typescript": "^5.4.2" } } ``` 此模板为构建模拟 MCP 服务器提供了坚实的基础。 请记住根据你的特定需求进行调整，并为你的项目添加必要的功能。 祝你好运！ ```
