groowooth
MCP server that enables AI agents to assess child growth, plot growth curves, and interpret z-scores using WHO and China NHC standards.
README
groowooth
开源儿童成长曲线工具——支持 WHO + 中国卫健委标准,自带 AI agent 接入。 Open-source child growth curve toolkit — WHO + China NHC standards, with native AI agent (MCP) integration.

是什么
家长用浏览器记录孩子身高/体重/头围,按 WHO 2006/2007 或 中国卫健委 WS/T 423-2022 标准看百分位曲线。数据本地存(IndexedDB),零账号、零云、零广告。
同时提供 MCP server,让 Claude Desktop / Cursor / Cline 等 AI 客户端可以直接调用「评估生长」「画曲线」「解读 z-score」三个工具。

三层架构
@groowooth/core 纯 TS 计算库 + 标准数据,零 runtime deps(除 zod)
WHO 2006/2007 用 LMS Box-Cox;NHC 2022 用 SD 表分段线性内插

快速开始
先决条件
- Node.js 18+
- pnpm 10+
装依赖 + 跑
pnpm install
# 网页(开发模式,http://localhost:5173)
pnpm dev:web
# 网页(生产构建)
pnpm build:web
# 跑全部测试
pnpm test
# 单独构建核心库
pnpm --filter @groowooth/core build
# 构建 MCP server(产出 packages/mcp/dist/server.js)
pnpm --filter @groowooth/mcp build
接入 Claude Desktop
构建后在 Claude Desktop 配置文件加:
{
"mcpServers": {
"groowooth": {
"command": "node",
"args": ["/path/to/groowooth/packages/mcp/dist/server.js"]
}
}
}
然后在 Claude 里直接说「我家娃 24 个月,身高 86 cm,体重 12 kg,按卫健委标准评估一下」即可。
核心 API
所有标准数据都是按需懒加载的。自 v0.1.0 起,核心 API 全部为 async;如果页面首屏一定会用到某个标准,可在 mount 时先 await loadStandard('nhc-2022') 预热。
import { assess, interpret, loadStandard, lookup, renderChart } from '@groowooth/core'
await loadStandard('nhc-2022')
// 评估
const result = await assess({
ageMonths: 24,
sex: 'female',
heightCm: 86,
weightKg: 12,
standard: 'nhc-2022',
})
// → { assessments: [...], standard, standardVersion, disclaimer }
// 查曲线数据
const curves = await lookup({
standard: 'who-2006',
indicator: 'height-for-age',
sex: 'male',
xRange: [0, 60],
percentiles: [3, 15, 50, 85, 97],
})
// 渲染 SVG
const svg = await renderChart({
standard: 'nhc-2022',
indicator: 'height-for-age',
sex: 'female',
measurements: [{ x: 24, value: 86 }],
})
// 中文统计描述(无临床建议)
const text = await interpret({
zScore: 0.31,
indicator: 'height-for-age',
sex: 'female',
ageMonths: 24,
})
设计原则
- 一件事:只做曲线,不做喂奶/睡眠/辅食/疫苗/社区
- 不诊断:v1 只输出统计描述("位于第 62 百分位"),不输出"矮小/肥胖/正常"等临床词;每个返回带
disclaimer - 本地优先:web 用 IndexedDB;MCP stateless(数据由调用方传,服务端 0 儿童数据)
- 多端共享同一份逻辑:web 和 mcp 都消费
@groowooth/core - 足月儿假设:v1 不支持早产儿矫正与 Fenton;v1.1 roadmap
