镜像概述

Code Runner MCP Server是一款用于运行代码片段并展示结果的MCP服务器，支持多种编程语言，可集成到VS Code、Claude Desktop等应用中，帮助用户快速验证代码逻辑。

核心功能

• 支持多种编程语言：JavaScript、PHP、Python、Perl、Ruby、Go、Lua等（完整列表可查看https://github.com/formulahendry/mcp-server-code-runner/blob/main/src/constants.ts%EF%BC%89
• 与MCP协议兼容，可轻松集成到支持MCP的应用中
• 提供多种安装方式（npx、Docker、Smithery），适配不同场景需求

使用场景

• 快速验证代码片段的执行结果
• 测试小型功能模块的逻辑正确性
• 获取系统信息（如CPU数量、临时文件夹路径）
• 学习多种编程语言时的代码调试

配置说明

npx安装（VS Code）

可通过按钮直接安装，或在settings.json中添加以下配置：

json
{
  "mcp": {
    "inputs": [],
    "servers": {
      "mcp-server-code-runner": {
        "command": "npx",
        "args": [
          "-y",
          "mcp-server-code-runner@latest"
        ]
      }
    }
  }
}

npx安装（Claude Desktop）

在claude_desktop_config.json中添加配置：

json
{
  "mcpServers": {
    "mcp-server-code-runner": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-server-code-runner@latest"
      ]
    }
  }
}

Docker部署（VS Code）

通过按钮安装，或在settings.json中配置：

json
{
  "mcp": {
    "inputs": [],
    "servers": {
      "mcp-server-code-runner": {
        "command": "docker",
        "args": [
          "run",
          "--rm",
          "-i",
          "formulahendry/mcp-server-code-runner"
        ]
      }
    }
  }
}

Smithery安装

通过Smithery在Claude Desktop中自动安装：

bash
npx -y @smithery/cli install @formulahendry/mcp-server-code-runner --client claude

Windows下npx问题解决

若Windows上npx连接失败，可尝试以下方法：

1. 使用bunx：安装https://bun.sh/docs/installation%E5%90%8E%EF%BC%8C%E5%B0%86%E9%85%8D%E7%BD%AE%E4%B8%AD%E7%9A%84%60npx%60%E6%9B%BF%E6%8D%A2%E4%B8%BA%60bunx%60
2. 使用cmd：在VS Code的settings.json中配置：

json
{
  "mcp": {
    "inputs": [],
    "servers": {
      "mcp-server-code-runner": {
        "command": "cmd",
        "args": [
          "/c",
          "npx",
          "-y",
          "mcp-server-code-runner@latest"
        ]
      }
    }
  }
}

使用示例

在已配置该服务的应用中，可尝试以下指令：

• Run the JavaScript Code: console.log(5+6)
• Where is temporary folder in my OS? Use run-code tool
• How many CPUs do I have in my machine? Use run-code tool
