## Description

Planning an event used to mean ordering massive amounts of food just in case, which always resulted in mountains of expensive leftovers or, worse, running out entirely. This MCP changes that by acting as a precise estimation engine for catering needs. You feed it the basic parameters—like how many people are coming and if it's a casual lunch or a formal dinner—and it spits out actionable numbers. It calculates ideal portions not just for proteins and sides, but also estimates exactly how much beverage capacity you need to cover the event duration.

When you connect this MCP via Vinkius, your AI client runs the necessary calculations instantly. You can figure out if a formal service requires different ratios than a buffet setup. It handles everything from calculating main course weights to checking the overall risk of waste, giving you confidence in your final order.

```

**Response:** 
```
For 50 guests at a buffet with a high appetite level, you will need approximately 12,500 grams of main course protein.

## Capabilities

### Calculate Main Course Portions
It determines the exact required weight for the central protein and meat dishes.

### Estimate Sides and Starches
This function calculates the optimal amounts of vegetables, starches, and accompanying side dishes.

### Estimate Beverage Requirements
It provides a calculated total volume needed for drinks based on event length and guest count.

### Analyze Waste Risk
The MCP assesses your current plans against historical data to pinpoint potential food waste risks before the event starts.

## Use Cases

### The Corporate Buffet Nightmare
A marketing director needs to cater a 200-person corporate lunch. Instead of ordering huge amounts just in case, they ask their agent to run the Leftover Ratio Calculator. It uses `calculate_main_course_portions` and `calculate_sides_and_starches` to give them exact grams for everything, saving them about $1,500 on over-ordering.

### The Gala Dinner Audit
A catering manager is planning a formal 3-hour dinner. They run the tool and it flags high waste risk because of an overly rich menu combination. The MCP suggests adjusting starches, allowing them to keep the luxury feel while significantly cutting down on food scraps.

### The Casual Pop-Up Event
An organizer is hosting a casual outdoor event for 50 people and isn't sure about drinks. They run `estimate_beverage_requirements` with the duration, and it tells them to prep exactly 12 liters of beverages, preventing them from buying unnecessary coolers full of wasted soda.

## Benefits

- Stop guessing on proteins. Use `calculate_main_course_portions` to get the precise weight of meat needed for your guest count, eliminating guesswork and costly shortages.
- Cut waste immediately. Running `analyze_waste_risk` tells you where your menu is weak before you even send out an invoice, saving money right away.
- Perfect sides every time. This MCP handles more than just mains; use `calculate_sides_and_starches` to nail the ratios for rice, potatoes, and veggies.
- Know your drink limits. Never run out of water or soda again. Use `estimate_beverage_requirements` to match consumption to event length.
- Time savings are huge. Instead of cross-referencing three different industry guides, you get one definitive calculation using the entire suite of tools.

## How It Works

The bottom line is you get an exact inventory list that minimizes ordering excess while guaranteeing enough high-quality food for everyone attending.

1. Provide the necessary inputs: the total number of guests, the expected meal type (e.g., buffet, seated), and the estimated time frame for the event.
2. Your AI client calls the required tools, such as `calculate_main_course_portions` and `estimate_beverage_requirements`, running multiple ratio calculations simultaneously.
3. The MCP delivers a single, consolidated report detailing precise weights for every food category and total beverage volume needed.

## Frequently Asked Questions

**How does Leftover Ratio Calculator handle different meal types?**
It adjusts ratios based on formality. For example, a formal dinner is calculated differently than a casual buffet because of varied portioning styles and appetite levels.

**Can I use Leftover Ratio Calculator for non-food items?**
No, this MCP focuses specifically on calculating food weight (proteins, sides) and liquid volumes. It's designed solely for catering logistics.

**Does the Leftover Ratio Calculator predict guest appetite?**
It uses structured inputs regarding expected appetite levels—like 'high' or 'average'—to adjust portions, which is more accurate than a simple count.

**Which tool do I use for beverage planning? Leftover Ratio Calculator MCP**
You must use `estimate_beverage_requirements`. This function requires the event duration and guest count to calculate total liters needed, not just a single number.

**How accurate is the waste analysis from Leftover Ratio Calculator?**
It uses established industry metrics against your inputs. While it's an estimation engine, running `analyze_waste_risk` flags major inconsistencies in your plan immediately.
