McDonald's Coupon Assistant

A skill that connects to McDonald's China MCP Server to help users discover promotions, claim coupons, and manage their coupon wallet.

Overview

This skill uses McDonald's official MCP (Model Context Protocol) service to:

• Query available coupons (麦麦省)
• One-click claim all coupons
• Check campaign calendar
• View user's coupon wallet

Token Management

Check if Token Exists

First, check if user has configured a token:

python scripts/token-manager.py list

No Token? Guide User to Get One

📝 首次使用需要 MCP Token

获取步骤:
1. 访问 https://open.mcd.cn/mcp
2. 点击右上角「登录」
3. 使用手机号验证登录
4. 点击「控制台」→「激活」
5. 复制生成的 Token

添加 Token:
python scripts/token-manager.py add <名称> <token>

示例:
python scripts/token-manager.py add personal 1kxNLFYT...

Multi-Token Management

Users can manage multiple tokens with custom nicknames:

# Add tokens - nickname can be anything user wants
python scripts/token-manager.py add 我自己 <token1>
python scripts/token-manager.py add 老妈 <token2>
python scripts/token-manager.py add 女朋友 <token3>

# List all tokens
python scripts/token-manager.py list
# Output:
# 🎫 已保存的 Token:
# ----------------------------------------
#   我自己: 1kxNLFYT...LuqJ ← 当前
#   老妈: 2abCDEFG...XyZ
#   女朋友: 3mnOPQRS...123
# ----------------------------------------

# Switch active token
python scripts/token-manager.py switch 老妈

# Remove a token
python scripts/token-manager.py remove 女朋友

Storage: ~/.mcd-tokens.json (auto-created, permissions 600)

Token is cached persistently - user only needs to add once, then it's always available.

Quick Reference

Implementation

Using Helper Script (Recommended)

# Uses token from token manager automatically
python scripts/mcd-mcp.py available-coupons

# Or specify token directly
python scripts/mcd-mcp.py available-coupons <token>

Direct HTTP Call

curl -X POST https://mcp.mcd.cn/mcp-servers/mcd-mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $TOKEN" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"available-coupons"}}'

Response Parsing

{
  "result": {
    "content": [{"type": "text", "text": "...coupon data..."}]
  }
}

Extract text: result.content[0].text

Example Workflows

User: "有什么麦当劳优惠？"

1. Check token exists → if not, guide user to add
2. Call available-coupons
3. Present coupons with prices
4. Offer to claim all

User: "帮我领券" / "一键领取"

1. Call auto-bind-coupons
2. Report success count
3. Remind expiry dates

User: "切换到我妈的账号领券"

1. Run python scripts/token-manager.py switch 老妈
2. Then call auto-bind-coupons
3. Confirm: "已用「老妈」的账号领取了 X 张券"

User: "帮我把女朋友的麦当劳加进来"

1. Guide to get token from https://open.mcd.cn/mcp
2. Ask user for nickname: "你想给这个账号起什么名字？"
3. Run python scripts/token-manager.py add <用户起的名字> <token>
4. Confirm addition

Response Style

When presenting coupon info:

• Use emojis for food (🍔🍟🍗)
• Highlight prices and savings
• Group by category
• Note expiration dates
• Show which account is active (if multiple)

Common Issues

Rate Limits

• 600 requests per minute per token
• Each token is independent (can use multiple accounts in parallel)
