Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@midea-mcp set bedroom AC to 24°C cool mode"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
midea-mcp
面向美的空调的本地单用户 MCP Server。MVP 使用 Python 3.12、MCP Python
SDK >=1.27,<2 和 stdio,公开七个工具:
list_devicesget_deviceget_device_logrefresh_deviceset_device_statediscover_lan_devicesdiagnose_device
设备状态日志
所有 set_device_state 调用都会写入 data/device-log.jsonl,包括请求字段、
Provider、五种写入状态、核验结果和失败原因。每次真实设备状态读取都会与上一份
持久化快照比较,并分别记录:
state_change:开关、模式、设定温度;sensor_change:室内温度;availability_change:在线状态;state_snapshot:首次读取时建立的基线。
每条记录同时包含 UTC 和北京时间。通过 midea-mcp 写入后的读回带有同一个
request_id;其他入口造成的变化标记为 external_unknown。observed_via=cloud
只表示变化是通过云端读取发现的,不能证明操作来自美居 App。
读取最近日志:
get_device_log(limit=50)
get_device_log(limit=50, field="mode")
get_device_log(limit=50, event_type="state_change")可过滤字段为 power、mode、target_temperature、current_temperature 和
online,limit 范围为 1–500。日志只在真实状态读取发生时发现外部变化;
midea-mcp 本身不会后台轮询设备。

安全与一致性保证
每台逻辑设备使用 midea-mcp 内部 UUID。
Cloud ID、LAN ID 和 keyed SN fingerprint 分别保存为 bindings,绝不假设 Cloud ID 与 LAN ID 相同。
写入只返回
rejected、not_delivered、delivery_unknown、accepted或verified。LAN 或 Cloud 写入投递结果不明时,只通过原 Provider 读取实际状态进行核验, 绝不切换 Provider 或重发。
Token/Key 使用 AES-256-GCM 加密落盘;日志和工具响应不返回明文凭证或原始 SN。
路由选择为“可用 LAN 优先;没有可用 LAN binding 时使用 Cloud”。一旦开始写入, 本次请求就锁定 Provider。
Cloud 支持空调状态读取及开关、模式、目标温度写入,并使用云端状态读回核验。
安装
py -3.12 -m venv .venv
.\.venv\Scripts\python.exe -m pip install -e ".[dev]"如果系统没有 py 命令,直接使用 Python 3.12 可执行文件创建虚拟环境。
默认数据目录是当前目录下的 data/,可通过 MIDEA_MCP_DATA_DIR 修改。
首次启动会生成 data/master.key。生产使用时应备份密钥并限制文件访问权限;也可以
使用 MIDEA_MCP_MASTER_KEY 注入一个 URL-safe base64 编码的 32 字节密钥。
Phase 0
1. 局域网扫描
.\.venv\Scripts\midea-mcp.exe phase0跨子网或广播受限时可指定设备 IP 或广播地址:
.\.venv\Scripts\midea-mcp.exe phase0 --target 192.168.1.2552. 导入旧 HA V3 凭证
midea_ac_lan 的单设备文件通常位于:
<HA config>/.storage/midea_ac_lan/<device_id>.json可导入单个文件、整个 midea_ac_lan 目录,也可导入 HA
.storage/core.config_entries:
.\.venv\Scripts\midea-mcp.exe import-ha C:\path\to\123456789.json导入器仅接受设备类型 0xAC、协议版本 V3,并将 Token/Key 立即加密后保存。
3. 可选的 Cloud 库存及 Token/Key 补取
不要把账号密码写入命令行历史:
$env:MIDEA_ACCOUNT = "your-account"
$env:MIDEA_PASSWORD = "your-password"
$env:MIDEA_CLOUD_NAME = "美的美居"
.\.venv\Scripts\midea-mcp.exe sync-cloud旧 Token API 正在被美的关闭,因此该步骤可能无法取得新凭证。已有 HA 凭证优先且 不会被云端候选覆盖。Cloud/LAN 只有在 SN fingerprint 唯一匹配时才合并为同一设备。
sync-cloud 同时会登记 Cloud binding。部署在无法访问家庭局域网的服务器时,应在
启动 MCP Server 前至少执行一次该命令;之后 refresh_device 和
set_device_state 会通过 Cloud 路由工作。
4. 加密备份
.\.venv\Scripts\midea-mcp.exe backup-credentials C:\safe\midea.backup.json
.\.venv\Scripts\midea-mcp.exe restore-credentials C:\safe\midea.backup.json备份使用独立口令通过 scrypt 派生密钥,再使用 AES-256-GCM 加密。
启动 MCP Server
.\.venv\Scripts\midea-mcp-server.exe客户端配置示例:
{
"mcpServers": {
"midea": {
"command": "C:\\path\\to\\midea-mcp\\.venv\\Scripts\\midea-mcp-server.exe",
"env": {
"MIDEA_MCP_DATA_DIR": "C:\\path\\to\\midea-mcp\\data"
}
}
}
}控制参数
set_device_state 只接受:
{
"device_id": "midea-mcp-internal-uuid",
"changes": {
"power": true,
"mode": "cool",
"target_temperature": 26
}
}模式为 off / auto / cool / dry / heat / fan_only,目标温度默认限制
为 17–30°C,步长 0.5°C。power=false 不能与模式或温度同时提交。
当前不做
热水器、烤箱及其他设备品类
场景和
execute_sceneHome Assistant Provider
多用户或公网认证
测试
.\.venv\Scripts\python.exe -m pytest
.\.venv\Scripts\python.exe -m ruff check .测试使用模拟 Provider,不会控制真实设备。实机写入只通过显式调用
set_device_state 发生。
本次 Phase 0 与实机验收结果见 PHASE0.md。项目已发现并登记 一台 V3 空调,通过云端 Token API 候选完成 LAN 认证,并实际验证开关、模式 和温度控制。验收结束后设备已恢复为关机、25°C。

Scored across 6 tools
Each tool has a clearly distinct purpose: retrieving device info, refreshing state, listing devices, setting state, discovering LAN devices, and diagnosing. No overlap or ambiguity.
All tool names follow a consistent verb_noun pattern using lowercase snake_case (get_device, refresh_device, list_devices, set_device_state, discover_lan_devices, diagnose_device).
With 6 tools covering listing, retrieval, state refresh, state setting, discovery, and diagnostics, the set is well-scoped for managing Midea air conditioners without being excessive or insufficient.
The tool set covers core operations: listing, reading, refreshing, setting state, discovering, and diagnosing. Minor gaps like device deletion or cloud-only refresh are absent but not critical for the intended domain.
