麦门双预算军师——一个人吃，告诉它多少钱多少卡，它配出三档最划算的一顿；一群人吃，告诉它几个人什么场景，它算出整桌怎么拼单、比各点各的省多少，并生成点单接龙。输入示例：「30 块 600 卡」「4 个人 150 块聚餐怎么点」。.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# 麦门双预算军师 (McDualBudget Coach)

> 钱是一个预算，热量是另一个预算。两个都不超，一顿配到位。

## 实测情报（2026-10-09 校准，必读）

以下全部来自对 `https://mcp.mcd.cn` 的真机实测，写死在本 Skill 里，运行时不必重新探索：

### 枚举值（写死，不要猜）

| 参数 | 取值 |
|---|---|
| `beType` | 1=到店自提，2=麦乐送到家，5=得来速DT，6=企业团餐 |
| `orderType` | 1=到店（含自取+DT），2=外送（含麦乐送+团餐） |
| `searchType`（query-nearby-stores） | 2=按位置搜索，1=搜索收藏餐厅 |

### 关键坑（实测踩过）

1. **价格单位是「分」**：`calculate-price` 返回 `price: 2650` = ¥26.5。展示前必须 ÷100。
2. **`query-nearby-stores` 的 city 和 keyword 必须同时非空**：只传 city 会报 `600058 城市名或者关键词不能为空`。city 传城市名，keyword 传区域/地标关键词（如「仓山」「万达」）。
3. **`query-meals` 的返回已升级（2026-10-25 复测，旧记录作废）**：现在直接返回 `data.meals[code]` 完整实体——`name` / `image` / `currentPrice`（现价）/ `originalPrice`（划线价）/ `discountType` / `withOrder`（随单购）。**不必再逐个 `calculate-price` 补名称和价格**；`originalPrice` 还能直接算「省多少」。旧版只给 `code + tags` 的写法仍兼容，但属于浪费调用。
   - 热量仍需 `list-nutrition-foods` 按名称匹配；**新品（龙焰系列、韩式炸鸡、薄皮 V 翅等）营养表查不到**，必须标「未知」，不得估算
   - 价格单位：`query-meals` 的 `currentPrice` 是**元**（字符串，如 "26.9"）；`calculate-price` 返回的 `price` 仍是**分**，两者别混
   - `query-meal-detail` 的参数名是 **`code`**，不是 `mealCode`（传错会报 `400 code不得为空白`）；返回 `rounds[].choices[]`，`isDefault=1` 是默认档，`diffPrice` 是换档差价

How to install

The exact contents, by fingerprint
mdr add erikzeng2008-del/mcd-dual-budget-coach/mcd-dual-budget-coach@sha256:460d5eb63c8b5a4f

The line at the top of this page pins the label v0.3.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
