## Description

You shouldn't have to do mental math at the grocery aisle to know if a bulk pack is actually a deal. This MCP acts as a decision engine for your shopping strategy. It moves beyond simple unit pricing to account for the hidden costs of buying in volume, like the physical space required in your pantry or the waste generated by oversized packaging. 

When you use this with your agent, you can run complex comparisons between different package sizes to see which one hits the sweet spot for your budget. It helps you decide if buying a massive container of coffee is a smart move or if you'll just end up with a stale product that takes up too much shelf space. By analyzing lifecycle costs and purchase frequency, you can build a shopping plan that balances upfront savings against your actual consumption rates and available storage.

## Tools

### calculate_lifecycle_cost

## Prompt Examples

**Prompt:** 
```
Which of these three milk packages is the best deal: 1L for $2.00, 2L for $3.50, or 4L for $6.00? Use 1000ml as the target unit.
```

**Response:** 
```
The 2L package is the best deal with a unit price of $1.75 per liter.
```

**Prompt:** 
```
How much will I spend on coffee over 6 months if I use 500g per month and the package is 1kg for $15?
```

**Response:** 
```
You will spend $45.00 over 6 months, requiring 3 purchases of the 1kg package.
```

**Prompt:** 
```
I have 10 liters of space. Is it better to buy a 5L detergent for $10 or a 12L detergent for $22?
```

**Response:** 
```
The 5L detergent is the only viable option as the 12L package exceeds your available storage volume.
```
