# Price per 100g Calculator MCP. AI Agent Connect

> Price per 100g Calculator MCP lets your AI client normalize different product prices to a single 100g standard. Instead of guessing which bulk item is actually cheaper, you can use this MCP to calculate exact unit costs, convert weights, and compare multiple items at once to find the best value.

## Description

Stop guessing which package size gives you the most for your money. This MCP handles the math required to normalize any product price to a standard 100g unit. When you're looking at different brands or sizes, the raw price rarely tells the whole story. Your AI agent can use these tools to strip away the confusion of varying weights and packaging. You can feed it a list of items with different weights and prices, and it will tell you exactly which one is the best deal. It handles the unit conversions for you, so you don't have to worry about switching between grams and kilograms manually. It's a straightforward way to bring mathematical precision to your shopping decisions or price analysis tasks.

## Tools

### batch_calculate_normalized_prices
This tool processes a large set of pre-normalized data to perform mass calculations. It's built for handling groups of prices all at once.

### calculate_unit_price
This tool finds the price per 100 grams for a specific item. You provide the price and weight, and it returns the normalized value.

### compare_unit_prices
This tool identifies the best value among several different products. It compares their 100g unit prices to show you the winner.

### get_weight_conversion_factor
This tool determines the ratio between a specific weight unit and grams. It helps your agent handle different measurement types accurately.

## Prompt Examples

**Prompt:** 
```
Calculate the price per 100g for a 500g bag of coffee that costs $8.00.
```

**Response:** 
```
The price per 100 grams for the coffee is $1.60.
```

**Prompt:** 
```
Which is a better deal: 250g for $3.00 or 1kg for $10.00?
```

**Response:** 
```
The 1kg product is the better deal at $1.00 per 100g, compared to $1.20 per 100g for the 250g product.
```

**Prompt:** 
```
What is the conversion factor for kg to grams?
```

**Response:** 
```
There are 1000 grams in 1 kilogram.
```

## Capabilities

### Unit Price Normalization
Your agent converts any product price into a standard 100g cost.

### Bulk Price Comparison
The AI compares multiple items to find the lowest cost per unit.

### Weight Conversions
Your agent calculates the relationship between different weight units and grams.

### Mass Data Processing
The AI runs calculations on entire sets of pre-normalized pricing data.

## Use Cases

### Grocery Shopping
Compare a small jar of peanut butter against a large tub to see which is cheaper per gram.

### Retail Price Audits
Analyze a list of product prices to find discrepancies in unit value across different brands.

### Inventory Costing
Calculate the standardized cost of bulk ingredients for recipe or production planning.

### Bulk Buying Decisions
Determine if buying in larger quantities actually saves money compared to smaller units.

## Benefits

- Removes the guesswork from comparing different package sizes.
- Standardizes all pricing to a 100g metric for easy comparison.
- Automates weight conversions between grams and kilograms.
- Identifies the best value in a list of multiple products.

## How It Works

Connect the MCP to your client and start asking for price comparisons.

1. Connect your AI client to the Vinkius hosted MCP.
2. Provide the product price and weight to your agent.
3. The agent uses the tools to normalize the price to 100g.
4. The agent compares the results to give you the final answer.

## Frequently Asked Questions

**What is the standard unit for comparison?**
All prices are normalized to a 100g standard to ensure a fair comparison.

**Can I compare multiple items at once?**
Yes, you can use the comparison tool to find the best value among several products.

**Does this work with kilograms?**
Yes, the MCP includes tools to handle weight conversions between various units and grams.

**Which AI clients can use this MCP?**
You can use this with any MCP-compatible client like Claude, Cursor, Windsurf, or VS Code.

**Do I need to host this myself?**
No, Vinkius hosts and manages the MCP for you, so it's ready to use immediately after connection.

**How do I compare two different sized products?**
You can use the `compare_unit_prices` tool by providing a list of products with their total price and weight. It will identify the cheapest option based on the 100g standard.

**What weight units are supported?**
The server supports grams (g) and kilograms (kg) via the `calculate_unit_price` and `get_weight_conversion_factor` tools.

**Can I process multiple products at once?**
Yes, use `compare_unit_prices` for comparing different products or `batch_calculate_normalized_prices` if you already have the normalized 100g values.
