README

toolbox-mcp

一个工具型 MCP Server(Tools-only),演示「AI Host → MCP 协议 → 多语言后端」的完整调用链。

三层架构:

层 语言 职责
胶水(协议 + 进程桥) TypeScript / Node MCP 协议、工具注册、spawn C++ 子进程
内核(计算) C++ 纯计算内核(如 twoSum 两数之和)

目录结构

toolbox-mcp
├── src/            TS 胶水层
│   ├── server.ts   主入口(serveStdio + 6 个 register)
│   ├── pathGuard.ts 路径守卫(限制读写 data/)
│   └── tools/      6 个工具
├── native/         C++ 内核
│   ├── 001.cpp     twoSum 源码
│   └── 001.exe     编译产物(不提交,见下)
├── data/           读写文件工具的操作目录
└── TODO.md         开发计划(#8 Web 面板待办)

环境要求

  • Node.js ≥ 20
  • MinGW g++(编译 C++ 内核用,仅 two_sum 工具需要)

安装

npm i

编译 C++ 内核

native/001.exe 是编译产物,不入库。克隆后需自行编译:

g++ -O2 -std=c++20 -static-libgcc -static-libstdc++ native/001.cpp -o native/001.exe

-static-libgcc -static-libstdc++ 让 exe 自带运行时,避免依赖 libstdc++-6.dll。

运行

npm run dev    # 开发(tsx watch)
npm start      # 运行
npm run typecheck   # 类型检查(tsc --noEmit)

工具列表

工具 说明 层
echo 回显消息 TS
add 两数相加 TS
reverse 反转字符串 TS
read_file 读取 data/ 内文件 TS
write_file 写入 data/ 内文件 TS
two_sum 两数之和(spawn C++ 内核) TS → C++
