MCP server for executing shell, Python, and Node.js commands locally

Project description

timeverse-command-mcp

跨平台执行 shell / Python / Node 命令的 MCP (Model Context Protocol) Server

PyPI Python License


它能做什么?

让任意支持 MCP 的 AI 客户端(Timeverse Studio、Claude Desktop、Cursor、Continue 等)通过三个工具直接操作你的本地机器

工具 作用 适用平台
bash 执行 shell 命令 macOS / Linux / Windows
python 执行 Python 代码片段 全平台
node 执行 JavaScript 代码片段 全平台

典型用法(让 Claude 帮你做):

"用 bash 看一下 /tmp 目录下最大的 5 个文件"
"用 python 算一下 1+2+...+100"
"用 node 把这个 JSON 解析后告诉我 user.name"

安装

方式 1:pip(推荐)

pip install timeverse-command-mcp

安装完成后会得到一个 timeverse-command-mcp 命令。

方式 2:源码安装(开发用)

git clone https://github.com/elimyliu/timeverse-command-mcp.git
cd timeverse-command-mcp
pip install -e ".[dev]"

接入 Claude Desktop

编辑 Claude Desktop 配置文件(位置见下表):

操作系统 配置路径
macOS ~/Library/Application Support/Claude/claude_desktop_config.json
Windows %APPDATA%\Claude\claude_desktop_config.json
Linux ~/.config/Claude/claude_desktop_config.json

加入以下内容:

{
  "mcpServers": {
    "timeverse-command": {
      "command": "timeverse-command-mcp",
      "args": [],
      "env": {}
    }
  }
}

重启 Claude Desktop,工具列表中会出现 bash / python / node 三个工具。

详细配置说明、Cursor / Continue / Cline 等其他客户端的接入方式,请参考 docs/USAGE.md

Python API

除了作为 MCP Server,本包也可以作为 Python 库使用:

import asyncio
from timeverse_command import AsyncCommandSession

async def main():
    session = AsyncCommandSession(
        tool_call_id="demo-1",
        command="echo hello && echo world",
        tool_name="bash",
    )

    async for chunk in session.run():
        if chunk["stream"] == "stdout":
            print(f"[out] {chunk['delta']}")
        elif chunk["stream"] == "exit":
            print(f"[exit] code={chunk['exit_code']} status={chunk['status']}")

asyncio.run(main())

输出:

[out] hello
[out] world
[exit] code=0 status=success

更多 API(取消、全局执行器等)见 docs/USAGE.md


开发

# 克隆
git clone https://github.com/elimyliu/timeverse-command-mcp.git
cd timeverse-command-mcp

# 安装依赖(含 dev 工具)
pip install -e ".[dev]"

# 运行测试
pytest

# 代码风格
ruff check src/
ruff format src/

# 类型检查
mypy src/

协议

  • MCP 传输: stdio(标准)
  • 不依赖任何私有扩展,可在所有支持 MCP stdio 的客户端中使用
  • 增强能力(流式 / 取消 / 危险确认)由 TimeVerse Studio 客户端专属提供,其他客户端以"基础能力"运行
