local-only server

The server can only run on the client’s local machine because it depends on local resources.

Integrations

Allows deployment and integration as an NPM package, making the system information retrieval functionality available for other applications via package installation
Provides TypeScript interfaces for integrating with the system information retrieval functionality, enabling type-safe access to system data

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();
