Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@system-command-mcpshow me the current git status"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
system-command-mcp
跨平台系统命令 MCP Server。AI 使用稳定的 program + args[] 接口调用已注册程序，不需要选择 Bash、PowerShell 或 cmd.exe，也不需要用 which、where、command -v、Get-Command 探测工具。
工具
system_exec
program 枚举在 Server 启动时根据当前 PATH 自动生成：
{
"program": "git",
"args": ["status", "--short"],
"cwd": ".",
"timeoutMs": 30000
}参数不会经过 Shell 展开，$HOME、*.ts、&& 等会原样传递。
system_environment
返回平台、架构、根工作目录，以及逻辑程序名到真实可执行文件的映射。通常无需先调用；system_exec.program 的 Schema 已包含可用程序。

只暴露当前环境实际存在的程序。
当前限制
仅支持 stdio transport；
不支持管道、重定向、任意 Shell 脚本、交互式 TTY 或后台常驻进程；
默认超时 30 秒，stdout/stderr 分别保留最后 1 MiB；
cwd 必须位于 --root 内；
程序快照在启动时生成，环境变化后需重启 Server；
超时和取消只保证终止直接子进程，不保证清理完整进程树。
