MCP server connector for Walmart retail shopping — search products, manage cart, and track orders via browser automation.

For Agents

This connector enables autonomous shopping on behalf of your human. Agents can:

• Know what to buy: Understand shopping lists, dietary preferences, budget constraints, and seasonal needs
• Search intelligently: Find products with filters (price, ratings) and compare options
• Execute efficiently: Build a cart, review totals, and hand off for final purchase confirmation
• Track orders: Monitor delivery status and notify the user when items arrive

Example agent workflow:

User: "I need groceries for the week. My budget is $100, and I need vegetarian options."

Agent executes:

1. set_address → Get local store availability
2. search → "organic vegetables", max_price: 50
3. search → "rice, pasta, beans" with filters
4. get_product → Check nutrition and price for each
5. add_to_cart → Build optimized cart under $100
6. checkout → Review total ($94.32) and return summary to user
7. User approves → Agent completes purchase

All in one seamless agent turn.
