What it does
The `mcworth` skill runs on top of the official McDonald's China MCP (`https://mcp.mcd.cn`, 20 tools). It detects the current menu slot and time until it closes, loads the menu and calls price calculation, so it shows the real discounted price instead of an estimate. It proposes pickup and delivery plans, expands combo contents, tracks whether loyalty cards pay off and compares promotions. Ordering, buying a card and claiming coupons happen only after a list of amounts and a confirmation. Profile and order ledger stay local in `data/`.
Who it is for. McDonald's customers in mainland China who buy loyalty cards and coupons and want order savings calculated through an MCP client.
Good fit when
- Choosing lunch or breakfast with the coupons and discounts on the account.
- Deciding whether the breakfast card or the Gold card will pay off.
- Comparing pickup and delivery including the delivery fee.
- A scheduled morning reminder with a ready order plan.
Not a fit when
- You have no McDonald's China account and MCP token.
- You want ordering without personal confirmation of each amount.
- You need an official company product; this is a contest entry.
Example request
What should I get for lunch? Show two plans with the discounted price and say whether the card is worth it.Limitations
Works only with a mainland China account and a token issued at `open.mcd.cn/mcp`. The README and the skill are written in Chinese. It is a contest entry, not a McDonald's product. Last commit: October 2026. Prices and slots depend on the store and time. The token grants access to a personal account and paid actions, so keep it only in an environment variable and never hand it to unknown agents.
How to disable. Remove the skill folder from the agent workspace and delete the `mcd-mcp` entry from the MCP config. Revoke the token at `open.mcd.cn` and delete the local `data/` files by hand.
FAQ
Where do prices come from?
From the price-calculation tool of the official MCP. The README stresses that the skill estimates nothing by eye.
Can the skill order without asking?
No. Ordering, buying a card and coupons run after a list of amounts and the user's confirmation.
Where is data stored?
Profile, preferences and the order ledger stay local in `data/` and are not sent out.
How do I get a token?
A McDonald's China account and an application at `open.mcd.cn/mcp`. Keep the token in `MCD_MCP_TOKEN`, not in the repository.
Does it work outside WorkBuddy?
Yes, the README mentions Cherry Studio and Cursor: use the same MCP address, token and a `SKILL.md` in the skills folder.
