## Description

Splitting bills when your friends have wildly different incomes is always messy. You end up arguing over what 'fair' even means, often resorting to rough estimates that feel wrong. The Uneven Income Splitter changes that. Instead of dividing the cost by four (the simple but inaccurate method), this MCP uses everyone’s income as a weight to calculate individual responsibility. For example, if one person earns five times more than another, they should pay five times more toward shared expenses.

Using your AI client connected through Vinkius, you feed it the total bill and the list of incomes. The system instantly breaks down who owes what. It doesn't just give a guess; it provides an exact financial breakdown for every single person. You can even audit payments later on to make sure everyone paid exactly their calculated share, eliminating those annoying rounding discrepancies that always pop up at the end of the month.

This tool takes the guesswork out of group finance, letting you move past arguing and straight to enjoying the shared expense it was for.

## Prompt Examples

**Prompt:** 
```
Split a $600 utility bill for three roommates: Alex (income: 45k), Ben (income: 25k), and Chris (income: 80k).
```

**Response:** 
```
**💰 Proportional Split Calculation**

Based on your combined incomes, the split is calculated as follows:

*   **Chris:** $360.00 (Highest income)
*   **Alex:** $180.00
*   **Ben:** $60.00 (Lowest income)

Total: $600.00

This ensures the cost reflects individual earning power.
```

**Prompt:** 
```
Check if these payments for a $15,000 joint project are accurate: A paid 7k, B paid 3k, and C paid 5k. Their incomes are 40k, 20k, and 90k.
```

**Response:** 
```
**✅ Payment Verification Status**

## Capabilities

### Calculate precise expense splits
Determines the exact dollar amount each person must pay toward a total bill based on their income relative to the group.

### Determine individual contribution percentage
Calculates what exact weight or percentage of the collective responsibility belongs to a single participant.

### Audit payments for financial accuracy
Compares submitted payments against expected proportional shares, flagging any discrepancies in the group's finances.

## Use Cases

### Roommates splitting utility bills
A group needs to split a $400 utility bill. They feed their agent the total cost and everyone's incomes. The MCP returns specific dollar amounts, showing that Person A (higher income) owes significantly more than Person B (lower income), eliminating disputes over who pays what.

### Organizing a joint trip to Europe
The total cost of the trip is $8,000. The organizer uses the MCP with everyone's incomes. It generates an exact split showing that each person contributes according to their financial capacity, making the shared finances clear upfront.

### Auditing partnership expenses
A small business partner submits receipts and payments for a $12,000 joint marketing expense. The user runs `verify_payment_accuracy` to confirm that every payment aligns perfectly with the initial income-based split agreement.

### Calculating family contribution after an emergency
A large unexpected bill hits. The family uses the MCP, inputting the total cost and each member's current financial status to determine a fair, proportional payment plan that everyone can actually afford.

## Benefits

- You stop arguing over rounding errors. The `verify_payment_accuracy` tool automatically checks payments against expected proportional shares, guaranteeing financial integrity.
- The system moves beyond simple equal division. It uses income levels to calculate the true weight of each person's contribution, giving you a mathematically sound split.
- You get instant clarity on who pays what. Using `get_propose_split` provides an exact monetary breakdown for every participant with minimal input from your agent.
- You quantify fairness instantly. The ability to calculate the individual share percentage tells you exactly how much influence each person's income has on the total cost.
- The process is streamlined. Instead of manually calculating ratios and percentages, your AI client handles the complex math automatically.

## How It Works

The bottom line is that you tell your agent who paid what and who earned what; this MCP tells you if it all adds up fairly.

1. Provide your AI client with three pieces of data: the total bill amount, and a list of all participants along with their individual incomes.
2. The MCP calculates each person’s precise percentage contribution based on their income compared to the group's combined income.
3. It delivers an exact monetary breakdown for every participant, telling you exactly what they owe toward the shared expenses.
