Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

淘宝MCP演示服务器 - 提供基础工具和资源

Readme

MCP Demo Server

这是一个简单的MCP(Model Context Protocol)服务器示例,提供了基本的工具和资源。

功能

工具 (Tools)

  • add: 加法工具
    • 参数: a (数字), b (数字)
    • 返回: 两个数字的和

资源 (Resources)

  • greeting: 动态问候生成器
    • URI模式: greeting://{name}
    • 返回: 个性化的问候语

安装和运行

  1. 安装依赖:
npm install
  1. 运行服务器:
node server.js

客户端配置

方法1: 使用配置文件

创建 mcp-config.json 文件:

{
  "mcpServers": {
    "demo-server": {
      "command": "node",
      "args": ["server.js"],
      "cwd": "E:\\work\\python\\taobao-mcp-dev"
    }
  }
}

方法2: 环境变量配置

设置环境变量:

# Windows PowerShell
$env:MCP_SERVERS='{"demo-server":{"command":"node","args":["server.js"],"cwd":"E:\\work\\python\\taobao-mcp-dev"}}'

# 或者添加到系统环境变量

方法3: 在Cursor中配置

  1. 打开Cursor设置
  2. 找到MCP配置部分
  3. 添加服务器配置:
{
  "command": "node",
  "args": ["server.js"],
  "cwd": "E:\\work\\python\\taobao-mcp-dev"
}

测试服务器

测试加法工具

// 调用加法工具
const result = await mcp.callTool("add", { a: 5, b: 3 });
console.log(result); // 输出: 8

测试问候资源

// 访问问候资源
const greeting = await mcp.getResource("greeting://Alice");
console.log(greeting); // 输出: "Hello, Alice!"

故障排除

  1. 模块类型警告: 确保 package.json 中包含 "type": "module"
  2. 路径问题: 确保 cwd 路径正确指向项目目录
  3. 权限问题: 确保有执行 node 命令的权限

扩展

要添加新的工具,在 server.js 中使用 server.registerTool()

server.registerTool("toolName",
  {
    title: "工具标题",
    description: "工具描述",
    inputSchema: { param1: z.string(), param2: z.number() }
  },
  async ({ param1, param2 }) => ({
    content: [{ type: "text", text: "结果" }]
  })
);

要添加新的资源,使用 server.registerResource()

server.registerResource(
  "resourceName",
  new ResourceTemplate("resource://{param}", { list: undefined }),
  { 
    title: "资源标题",
    description: "资源描述"
  },
  async (uri, { param }) => ({
    contents: [{
      uri: uri.href,
      text: `资源内容: ${param}`
    }]
  })
);
