# Online Cart Optimizer is a decision engine. AI Agent Connect

> Online Cart Optimizer helps your AI client solve the math behind complex shopping carts. It evaluates product combinations against your budget, available coupons, shipping thresholds, and store inventory limits. Instead of guessing which items to buy to hit a discount, you let your agent run the numbers to find the cheapest, most efficient way to shop.

## Description

You can stop manually calculating whether a coupon is worth the extra item in your cart. This MCP handles the heavy lifting of shopping logic by treating your cart as a math problem. It looks at your budget, the specific rules of your coupons, and the shipping costs to find the best possible set of products. If you have a list of items and a limited budget, your agent can use this MCP to pick the exact combination that maximizes your value. It also checks if you've hit free shipping thresholds or if you're accidentally trying to buy more of an item than the store has in stock. It's a way to turn your AI client into a professional procurement assistant that ensures every order is valid and cost-effective.

## Tools

## Prompt Examples

**Prompt:** 
```
Find the best combination of products from this list: [{id: 'p1', price: 10, stockLimit: 5}, {id: 'p2', price: 20, stockLimit: 2}] with a budget of 25 and a 5 dollar coupon.
```

**Response:** 
```
The optimal selection is product p2 for a total of 15 dollars after the coupon is applied.
```

**Prompt:** 
```
Is the coupon 'SAVE10' valid for a cart containing product p1 (price 15) if the minimum spend is 20?
```

**Response:** 
```
No, the coupon is not valid because the current cart total is 15, which is below the required 20 minimum spend.
```

**Prompt:** 
```
What is the shipping cost for a 40 dollar cart if the free shipping threshold is 50 and the standard fee is 5?
```

**Response:** 
```
