What it does
The skill runs on top of the official McDonald's China MCP (`mcp.mcd.cn`). It reads order history through `order-list`, matches every item to a nutrition table and builds a per-day calorie calendar plus a habit profile: favourite items, weekdays against weekends, late-night orders, sugary drinks. Before the next order it estimates energy needs from height, weight and age with the Mifflin-St Jeor formula, sets a calorie target per meal and enumerates combinations of a main, a side and a drink. Among suitable options it picks the cheapest with coupons applied via `calculate-price`. The order goes to `create-order` only after explicit confirmation.
Who it is for. WorkBuddy users in China who order from McDonald's often and want calories and totals per receipt.
Good fit when
- You want to know how many calories a month of orders added up to.
- A McDonald's lunch has to fit roughly 650 kcal.
- A high-calorie item should be swapped for a similar one, such as regular cola for zero.
- Before ordering you want to see which coupons apply to the healthier set.
Not a fit when
- You need it outside China: the MCP and menu are tied to `mcp.mcd.cn`.
- You need exact clinical nutrition: the estimate is approximate.
- You want orders placed without confirmation: the skill asks for it explicitly.
Example request
Check my McDonald's orders for September, show a calorie calendar and pick a 650 kcal lunch with coupons, without placing the order.Limitations
The skill targets WorkBuddy and the Chinese McDonald's MCP: a token from the open platform, issued against a phone number, is required. Dishes missing from the nutrition table are marked as unknown calories and excluded from recommendations. The calorie target relies on a formula and the 2022 Chinese dietary guidelines and is not medical advice. The order step creates a real order and charges money, so confirm it by hand. The interface and docs are in Chinese.
How to disable. Delete the `mcd-fit-buddy` folder from `~/.workbuddy/skills/` and disable the `mcd-mcp` connector. Revoke the token in the platform console.
FAQ
Is a token needed to try it?
No. `python -m src.mcd_fit.cli demo` runs on sample data; a token is only needed for real orders.
How are calories counted?
Each order item is matched to a nutrition table. Refunded orders are skipped and items without data are not estimated.
Does the skill place an order on its own?
No. The `order` command with `--confirm` and the `create-order` step both need explicit confirmation.
Which agent is required?
The skill targets WorkBuddy and goes into `~/.workbuddy/skills/`. Other clients need a manual port.
How can I see a result without installing?
Open `demo/index.html` from the repository: it works without a server, on a data snapshot from 21 October 2026.
