miband-mcp
Enables AI to query Xiaomi Mi Band health data (steps, sleep, heart rate) from Gadgetbridge SQLite exports via the MCP protocol, allowing natural language questions about daily activity.

晨熹 · 让 AI 读懂你的手腕
零第三方依赖的 Python MCP Server:读取 Gadgetbridge 导出的 SQLite 数据库(小米手环健康数据),通过 MCP 协议暴露给任意支持 MCP 的 AI 客户端(Reasonix / Claude / Cursor / Kimi / GLM 等),让 AI 能回答"今天走了几步""昨晚睡得怎么样"。
架构
小米手环 9 / 9 Pro / 10 → Gadgetbridge(手机端采集)→ SQLite 导出 → miband-mcp(读库+聚合)→ MCP 协议 → AI
提供的工具
| 工具 | 参数 | 返回 |
|---|---|---|
get_hr |
count(默认 10,最大 100) |
最近 N 条心率(时间 + bpm) |
get_sleep |
date(默认今天) |
入睡/醒来时间、睡眠分期(light/deep/rem)、总时长 |
get_daily |
date(默认今天) |
步数、平均/最高/最低心率 |
快速开始
1. 准备数据源
- 手机安装 Gadgetbridge(官方仓库在 Codeberg,不是 GitHub)
- 按官方 配对指南 连接手环(小米手环 9 需手环主动发起连接:手环设置 → 系统操作 → 连接新手机)
- 从小米运动健康日志中提取 32 位
encryptKey作为配对密钥(注意:绑定后不可解绑,否则密钥失效) - Gadgetbridge 设置 → 自动化 → 开启 自动导出数据库
2. 运行 MCP Server
# 零依赖,纯标准库
python miband_mcp.py --db /path/to/gadgetbridge.db
3. 接入 AI(以 Reasonix 为例)
[[plugins]]
name = "miband"
type = "stdio"
command = "python"
args = ["<路径>/miband_mcp.py", "--db", "<路径>/gadgetbridge.db"]
auto_start = true
然后 /new 新会话即可生效。
⚠️ 当前限制
数据同步为手动模式:本项目读取的是 Gadgetbridge 导出的 SQLite 数据库快照,不会自动从手环拉取数据。
当前工作流:
- 手环数据由 Gadgetbridge 采集(需先同步)
- 手动将导出的数据库文件(
.db)发送到运行 miband-mcp 的电脑 - AI 通过 MCP 工具读取数据库中的最新数据
因此:AI 回答的是"最近一次同步的数据",不是实时数据。若需要实时读取,可结合 Termux 脚本 + 定时同步,将 .db 文件自动推送到电脑(本项目暂未实现,欢迎 PR)。
开发
python -m unittest discover -s tests -v # 34 个测试,零依赖
