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();
