Here is a step-by-step guide with screenshots.
simple-MCP
一个最小的 MCP (Model Context Protocol) server 示例,通过 stdio 暴露一个查询本机硬件信息的工具。
依赖
Python >= 3.13
Related MCP server: mcpscope
安装
uv sync运行
uv run main.pyserver 以 stdio 传输方式启动,等待 MCP 客户端连接。
工具
get_host_info
无参数,返回结构化的主机信息:
字段 | 类型 | 说明 |
| string | 操作系统名称,如 Darwin / Linux / Windows |
| string | 内核版本号 |
| string | CPU 架构,如 x86_64 / arm64 |
| string | 处理器标识,部分平台可能为空 |
| number | 物理内存总量,单位 GB |
| integer | 逻辑核心数,无法探测时为 -1 |
| string | CPU 型号名称,无法探测时为 Unknown |
返回类型是 pydantic model HostInfo,MCP 会据此生成自描述的 output schema,客户端无需解析字符串。
CPU 型号按平台探测:macOS 用 sysctl machdep.cpu.brand_string,Linux 读 /proc/cpuinfo,Windows 读 PROCESSOR_IDENTIFIER,全部失败时回退到 platform 模块。
客户端配置
{
"mcpServers": {
"hostInfoMcp": {
"command": "uv",
"args": ["--directory", "/path/to/simple-MCP", "run", "main.py"]
}
}
}本地验证
uv run tools.py # 直接打印主机信息 JSONMaintenance
