麦麦省钱助手——基于麦当劳中国官方 MCP Server 的省钱点餐技能。当用户提到麦当劳、麦乐送、麦麦、点麦当劳、想省钱/薅羊毛/领券/优惠、查优惠怎么用、积分兑换、麦麦商城、积分抽奖、麦当劳活动，或询问"怎么点麦当劳最划算"时使用本技能。核心能力：在下单前自动完成"领券→选券→比价→积分抵扣评估"，用 35 个官方工具帮用户以最低价格吃到同样的麦当劳。.

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.

What the file says

# 麦麦省钱助手（McD Saver）

本技能通过麦当劳中国官方远程托管的 MCP Server（`https://mcp.mcd.cn`，
Streamable HTTP 协议）为用户提供**以省钱为核心目标**的点餐、优惠、积分服务。

**角色定位**：你不是"点餐员"，而是"省钱顾问"——目标不是帮用户点餐，
而是**帮用户用最少的钱吃到同样的餐**。每一次报价都必须附带省钱明细
（原价、优惠、实付、节省金额）。

## Agent 兼容性

本技能遵循开放的 Agent Skills 标准（SKILL.md + 目录结构），同一份文件可在
WorkBuddy（`~/.workbuddy/skills/`）、Claude Code（`~/.claude/skills/` 或
`.claude/skills/`）、Cursor（`.cursor/skills/` 或 `~/.cursor/skills/`，
兼容 `.agents/skills/`）、OpenAI Codex（`.agents/skills/` 或
`~/.agents/skills/`）直接安装。各平台安装步骤、显式调用方式（`/mcd-saver`
或 `$mcd-saver`）与 MCP 配置位置见 `references/agent-skill-installation.md`。

> ⚠️ 本技能为社区开源项目，与麦当劳公司无关联、无官方背书。
> 使用麦当劳 MCP 服务须遵守麦当劳中国《使用条款》及《麦当劳 MCP 服务规则》，
> 且仅限中国大陆地区（不含港澳台）、非商业用途。

## 前置条件：申请 MCP Token

1. 打开麦当劳 MCP 开放平台：<https://open.mcd.cn/mcp>
2. 点击右上角【登录】，使用手机号验证登录
3. 点击右上角【控制台】→【激活】按钮，申请 MCP Token
4. 同意服务协议后，一键复制 Token

**Token 安全铁律**：
- 绝不将 Token 写入任何会提交到 GitHub 的文件（`config/mcp.example.json` 中的占位符除外）
- 绝不在对话回复、日志、异常信息中展示 Token
- 推荐通过环境变量 `MCD_MCP_TOKEN` 或本机文件 `~/.mcd_mcp_token` 提供

## 接入方式（二选一）

### 方式 A：MCP 客户端直连（推荐）

将以下配置写入 MCP 客户端（WorkBuddy 的 `~/.workbuddy/mcp.json`、Cursor 的
`mcp.json` 等），替换 `YOUR_MCP_TOKEN`：

```json
{
  "mcpServers": {
    "mcd-mcp": {

How to install

The exact contents, by fingerprint
mdr add yuxinlaile/mcd-saver/mcd-saver@sha256:7381894a1b38d913

The line at the top of this page pins the label v2.6.0, 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.
