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 🙏

获取当前环境的 mcp

Readme

env-mcp

一个用于获取当前环境系统信息的 MCP 工具包。

功能特性

  • 获取详细的系统信息
  • 支持跨平台使用
  • 易于集成到支持 MCP 的应用程序中
  • 提供 TypeScript 类型支持

安装

npm install @zhijianren/env-mcp -g

在支持 MCP 的应用中使用

1. 配置 MCP 服务

在应用的 MCP 配置中添加以下内容:

{
  "mcpServers": {
    "env-mcp": {
      "name": "env-mcp",
      "type": "command",
      "command": "node",
      "args": [
        "/usr/local/lib/node_modules/@zhijianren/env-mcp/dist/index.js"
      ],
      "enabled": true
    }
  }
}

2. 调用服务

// 获取平台信息
const platformInfo = await mcp.env.getPlatformInfo();

// 获取内存信息
const memoryInfo = await mcp.env.getMemoryInfo();

// 获取 CPU 信息
const cpuInfo = await mcp.env.getCpuInfo();

// 获取网络信息
const networkInfo = await mcp.env.getNetworkInfo();

// 获取用户信息
const userInfo = await mcp.env.getUserInfo();

// 获取 CPU 使用率
const cpuUsage = await mcp.env.getCpuUsage();

// 获取硬盘使用率
const diskUsage = await mcp.env.getDiskUsage();

// 获取终端类型
const terminalTypes = await mcp.env.getTerminalTypes();

// 获取 IPv4 信息
const ipv4Info = await mcp.env.getIpv4Info();

// 获取 IPv6 信息
const ipv6Info = await mcp.env.getIpv6Info();

// 获取代理信息
const proxyInfo = await mcp.env.getProxyInfo();

// 获取 Docker 信息
const dockerInfo = await mcp.env.getDockerInfo();

// 获取 Node.js 版本信息
const nodeInfo = await mcp.env.getNodeInfo();
