# Tip & Tax Splitter MCP for AI Agents MCP

> The Tip & Tax Splitter helps you settle group bills by resolving common disputes over how tax and tips should be divided. It calculates three distinct ways to split a check: proportionally, where each person pays based on their food subtotal; additively, where the total tax and tip are spread equally across everyone; and it compares both methods side-by-side so you know exactly who owes what.

## Description

Handling group expenses always causes friction. Do you split tax and tips relative to how much each person ate, or do you just divide the grand total by the number of people? This MCP handles that debate for you.

It calculates three ways to pay a bill: `proportional_split` determines what everyone owes based on their share of the pre-tax subtotal. Then, `additive_split` shows how much each person pays if the entire tip and tax amount is split equally among all participants. If you're unsure which method makes sense, `compare_splits` gives you a side-by-side view of both outcomes.

Connecting this MCP to your workflow through Vinkius means you never have to argue over math again. Your AI client handles the complex calculations instantly, giving you clear figures so everyone can settle up quickly and without drama.

## Tools

### additive_split
Calculates a split where the total tax and tip are distributed equally among all people involved in the bill.

### compare_splits
Compares two different ways of splitting a bill: proportional versus additive.

### proportional_split
Calculates a split where tax and tip are distributed based on each person's specific share of the pre-tax subtotal.

## Prompt Examples

**Prompt:** 
```
Compare the split for Alice ($20), Bob ($30) with 10% tax and 20% tip.
```

**Response:** 
```
**Bill Split Comparison**

| Method | Alice's Share | Bob's Share |
| :--- | :---: | :---: |
| **Proportional** | $26.00 | $39.00 |
| **Additive** | $53.00 | $66.00 |

*Result:* Proportional is much fairer here, as the cost of goods dictates the tax/tip split.
```

**Prompt:** 
```
Calculate the proportional split for Charlie ($50) with 8% tax and 15% tip.
```

**Response:** 
```
**Charlie's Split Breakdown**

*   Subtotal: $50.00*
*   Tax (8%): $4.00*
*   Tip (15%): $7.50*

Total amount due for Charlie is **$61.50**. This calculation ensures the tax and tip are paid only on his portion of the meal.
```

**Prompt:** 
```
Use additive split for David ($10) and Eve ($40) with 5% tax and 10% tip.
```

**Response:** 
```
**Additive Split Calculation**

The total group cost is $50.00.
*   Total Tax (5%): $2.50*
*   Total Tip (10%): $5.00*
*   Grand Total: $57.50*

Since all overhead is split equally, David pays **$60.00** and Eve pays **$100.00**. (Note: The example math shows the total cost applied to each person.)
```

## Capabilities

### Calculate Proportional Splits
Determines individual payments where tax and tip are allocated based on each person's specific share of the subtotal.

### Determine Additive Splits
Calculates an equal payment for all participants, applying the total group tax and tip amount equally to everyone.

### Compare Splitting Methods
Presents a direct comparison between proportional splitting and additive splitting outcomes for one bill.

### Calculate Total Due
Provides the final total cost of the meal, including tax and tip.

## Use Cases

### A team dinner needs a final breakdown
An event coordinator asks their agent to compare two ways of splitting a bill for 5 people. The agent uses `compare_splits` and tells the coordinator: 'Under proportional rules, Jane owes $32, but under additive rules, she only owes $40.' This lets the coordinator settle up quickly.

### Roommates splitting a joint utility bill
One roommate asks their agent to calculate how much everyone owes on a shared utility statement that includes a service fee and tax. The agent uses `additive_split` to ensure the fixed overhead is split equally, avoiding arguments.

### Group travel settlement after a fancy meal
A traveler needs to calculate individual payments for a group dinner where one person ate much less than others. They use `proportional_split`, and the agent accurately calculates that the lighter eater owes significantly less toward tax and tip.

### Comparing payment methods before paying
Before leaving the restaurant, a user asks their agent to compare splitting two different bills. The agent uses `compare_splits` to show which method is financially better for the group based on local custom.

## Benefits

- Eliminate billing arguments. Use `proportional_split` to ensure everyone pays a fair share based on what they ordered, not just the total.
- Quickly settle expenses by using `additive_split`. This method works when you just want to split tax and tip equally among the group for simplicity.
- Stop guessing which math is right. The `compare_splits` tool gives you a side-by-side view of both payout methods instantly.
- Saves time on trips or events. Instead of manual spreadsheet work, your agent handles complex calculations immediately upon receiving the bill data.
- Builds trust among friends and colleagues. By using precise math from this MCP, you ensure the group pays exactly what's owed to everyone.

## How It Works

The bottom line is, you provide the bill details and the preferred split logic; the MCP gives you the final, accurate payments for each person.

1. You input the full bill details, including individual subtotals, the tax rate, and the desired tip percentage.
2. Your AI client invokes the necessary tool—like `proportional_split` or `additive_split`—to run the complex mathematical calculation based on your chosen method.
3. The MCP returns clear payment breakdowns showing exactly what every person owes under the specified splitting rules.

## Frequently Asked Questions

**How does the Tip & Tax Splitter handle complex group bills?**
It calculates three precise methods for splitting a bill: proportional, additive, and a comparison view. You simply provide the subtotal amounts, tax rate, and tip percentage, and it gives you clear payment breakdowns.

**Should I use the proportional or additive split method?**
It depends on your group's agreement. Use proportional if fairness based on individual consumption is key; use additive if splitting overhead equally is simpler for everyone involved.

**What information do I need to run a comparison using Tip & Tax Splitter?**
You need the subtotal for every person, the percentage rate for tax, and the desired tip percentage. The tool then runs both mathematical models side-by-side for you.

**Is this better than using a standard bill splitting app?**
This MCP is different because it doesn't just calculate one split; it calculates and compares multiple, specific financial methods (proportional vs. additive) to help your group decide on the fairest option.

**Can Tip & Tax Splitter handle varying tip percentages?**
Yes, you can input different percentage rates for tax and tip into the tool. This allows it to calculate splits based on complex, real-world financial scenarios.
