千里马招标网站行业网站作用
效果演示
向大模型索要数据，并自动发送到指定邮箱
最后收到邮件的结果截图
先推荐2个mcp网站
mcp中文文档：https://mcpcn.com/docs/introduction/
mcp server收录站：https://mcp.so/
手搓的配套视频我放到文章底部
前置准备
我这边以node来做演示，node js环境点此下载，这个一定要有，没有现场装，啪的一下很快
// 检查node环境
node -v
// 检查npm环境
npm -v
// 检查npx环境
npx -v
// 配置淘宝源
npm config set registry https://registry.npmmirror.com
初始化mcp项目
# 创建一个文件夹（可手动创建）
mkdir first-mcp-server
cd first-mcp-server# 初始化 npm 项目
npm init -y# 安装mcp sdk依赖
npm install @modelcontextprotocol/sdk @anthropic-ai/sdk dotenv
npm install -D typescript @types/node# 创建 TypeScript 配置
npx tsc --init# 创建必要的文件
mkdir src
touch src/index.ts
加入如下代码
#!/usr/bin/env node
import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import {ListToolsRequestSchema,
} from "@modelcontextprotocol/sdk/types.js";const server = new Server({name: "first-mcp-server",version: "0.0.1",
}, {capabilities: {tools: {}}
});// List available tools 一定要有，否则无法接入mcp-client
server.setRequestHandler(ListToolsRequestSchema, async () => {return {tools: [{name: "测试方法",description: "这是一个测试方法描述",inputSchema: {type: "object",properties: {property1: {type: "string",description: "属性1",},property2: {type: "string",description: "属性2",},property3: {type: "number",description: "属性3，非必填",},},required: ["property1", "property2"],},},],};
});// 启动服务
async function main() {const transport = new StdioServerTransport();await server.connect(transport);console.error("First MCP Server running on stdio");
}// 异常捕获
main().catch((error) => {console.error("Fatal error in main():", error);process.exit(1);
});
tsconfig.json改为如下
{"compilerOptions": {"target": "ES2022","module": "Node16","moduleResolution": "Node16","outDir": "./build","rootDir": "./src","strict": true,"esModuleInterop": true,"skipLibCheck": true,"forceConsistentCasingInFileNames": true},"include": ["src/**/*"]
}
package.json加入如下代码
{"type": "module","scripts": {"build": "tsc","start": "node build/client.js"}
}
编译构建
打开命令行执行 npm run build，构建后会生成build/index.js文件
cherry-studio接入
注意：cherry-studio需要安装bun和uv，否则可能会报错
点击保存后会与你的mcp-代码建立连接，连接完成如下：
如果你做到了和我上面一样，那么接下来我们来实现发邮件的功能，代码如下：
#!/usr/bin/env node
import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import {ListToolsRequestSchema,CallToolRequestSchema,
} from "@modelcontextprotocol/sdk/types.js";
import * as nodemailer from 'nodemailer';const server = new Server({name: "email-mcp-server",version: "0.0.1",
}, {capabilities: {tools: {}}
});// 环境变量配置
const EMAIL_HOST = process.env.EMAIL_HOST || 'smtp.qq.com';
const EMAIL_PORT = parseInt(process.env.EMAIL_PORT || '465');
const EMAIL_USER = process.env.EMAIL_USER;
const EMAIL_PASS = process.env.EMAIL_PASS;if (!EMAIL_USER || !EMAIL_PASS) {console.error("EMAIL_USER or EMAIL_PASS environment variable is not set");process.exit(1);
}// 创建邮件传输器
const transporter = nodemailer.createTransport({host: EMAIL_HOST,port: EMAIL_PORT,secure: true,auth: {user: EMAIL_USER,pass: EMAIL_PASS,},
});// List available tools 一定要有，否则无法接入mcp-client
server.setRequestHandler(ListToolsRequestSchema, async () => {return {tools: [{name: "send-email",description: "发送邮件，支持HTML内容、表格和附件",inputSchema: {type: "object",properties: {to: {type: "string",description: "收件人邮箱，多个收件人用逗号分隔",},cc: {type: "string",description: "抄送邮箱，多个抄送用逗号分隔",},subject: {type: "string",description: "邮件主题",},html: {type: "string",description: "邮件HTML内容，支持表格等HTML标签",},attachments: {type: "array",description: "附件列表",items: {type: "object",properties: {filename: { type: "string" },path: { type: "string" }}}}},required: ["to", "subject", "html"],},},],};
});// 处理发送邮件请求
server.setRequestHandler(CallToolRequestSchema, async (request) => {try {if (!request.params.name || !request.params.arguments) {return {success: false,error: "Tool name and arguments are required"};}if (request.params.name === "send-email") {const args = request.params.arguments as {to: string;cc?: string;subject: string;html: string;attachments?: Array<{ filename: string; path: string }>;};if (!args.to || !args.subject || !args.html) {return {success: false,error: "Required fields missing: to, subject, and html are required"};}const mailOptions = {from: EMAIL_USER,to: args.to,cc: args.cc,subject: args.subject,html: args.html,attachments: args.attachments};const info = await transporter.sendMail(mailOptions);return {success: true,data: {}};}return {success: false,error: `Unknown tool: ${request.params.name}`};} catch (error) {return {success: false,error: error instanceof Error ? error.message : "Unknown error occurred"};}
});// 启动服务
async function main() {const transport = new StdioServerTransport();await server.connect(transport);console.error("First MCP Server running on stdio");
}// 异常捕获
main().catch((error) => {console.error("Fatal error in main():", error);process.exit(1);
});
这里增加了一个发送邮件的nodemailer依赖，所以需要npm安装一下
npm install --save @types/nodemailer
然后再次执行构建 npm run build，构建后去cherry-studio简单修改下属性点击保存
这里有几个参数我给个示例
EMAIL_HOST=smtp.qq.com
EMAIL_PORT=465
EMAIL_USER=88888888@qq.com
EMAIL_PASS=lrjlmbyslnxxxx
注意EMAIL_PASS需要手动去开启邮箱的smtp服务，开启后会有一个码，开启位置如下：
最后收到邮件的结果
