// MCP Server（Model Context Protocol）——挂在主服务的 /mcp 端点上
|
||
//
|
||
// 为什么不用官方 SDK / 不起新进程：
|
||
// 服务端全程零 npm 依赖（连密码哈希都是内置 Web Crypto），MCP 本质就是 JSON-RPC 2.0，
|
||
// 无状态 Streamable HTTP 模式只需要 POST + 响应。挂进现有 node-server.js 的 9522 端口，
|
||
// 复用同一套 systemd、访问日志与反代，不新增进程与攻击面。
|
||
//
|
||
// 传输形态（Streamable HTTP，无状态）：
|
||
// POST /mcp 单条 JSON-RPC 请求 → 单条响应；通知（无 id）→ 202 空响应
|
||
// GET/DELETE 405（不提供 SSE 长连接与会话）
|
||
//
|
||
// 安全模型：
|
||
// 1. Bearer Token，配置存 DB（app_settings 表）：后台「设置 → AI 接入 (MCP)」可随时
|
||
// 开关/轮换，即时生效无需重启。env MCP_AUTH_TOKEN 只做一次性种子：库里还没有
|
||
// 令牌时迁入 DB，之后以 DB 为准（换 env 不会顶掉已生成的令牌）。
|
||
// 两者都没配 → 端点关闭（404）。「没给钥匙的门直接不存在」比「存在但报 401」少暴露一层。
|
||
// 2. 只读工具：任何工具都不写库。补卡 / 改金额这类敏感操作永远不通过 MCP 暴露，
|
||
// AI 客户端最多能看，不能改。
|
||
// 3. 定长比较（timingSafeEqual）防逐字节探测 token。
|
||
//
|
||
// 引擎复用（本实现最重要的一条设计约束）：
|
||
// 所有算钱一律调 shared/payroll.js 的 aggregateMonth / flowsOf / penaltyDetails，
|
||
// 与前端看板同源。绝不把薪资规则复述给 AI 让它自己算——模型口算 19.5×7.5×28
|
||
// 迟早出错，而引擎带 100+ 基线用例。MCP 只做「取数 + 喂给引擎 + 结构化返回」。
