# Expense Growth Rate AI Agent Connect

> Expense Growth Rate MCP lets your AI agent handle the math behind your spending fluctuations. Instead of manually calculating percentage shifts between budget periods, you can ask your AI to find exact growth rates, generate descriptive reports, or categorize the intensity of cost changes across multiple expense pairs at once.

## Description

You can stop manually calculating percentage shifts between budget periods. This MCP gives your AI client the specific math tools it needs to interpret spending trends. If you need to know exactly how much a specific category jumped from last month to this month, your agent can pull that number instantly. You can also ask it to look at a long list of historical changes to find where your spending spiked or dropped most significantly. It doesn't just give you raw numbers, either. You can ask for a written summary of a change or have the AI categorize a price hike as significant or minor based on its magnitude. It turns raw expense data into actionable insights without you having to touch a calculator.

## Tools

### batch_growth_analysis
This tool scans a list of historical expense changes to identify the highest and lowest growth points.

### compare_expense_tiers
This tool assigns a qualitative tier to a growth rate to show how intense a change actually is.

### get_growth_rate
This tool calculates the exact percentage increase or decrease between a previous and current expense amount.

### get_growth_summary
This tool generates a text-based interpretation of a growth change for use in reports.

## Prompt Examples

**Prompt:** 
```
What was the growth rate if last month's expense was 100 and this month's is 125?
```

**Response:** 
```
The growth rate is 0.25, which represents a 25% increase.
```

**Prompt:** 
```
Give me a summary of the change from 500 to 450.
```

**Response:** 
```
Expenses decreased by 10%.
```

**Prompt:** 
```
Categorize the growth from 1000 to 1500.
```

**Response:** 
```
The change is categorized as Significant.
```

## Capabilities

### Percentage Calculation
Your AI client uses this to find the exact delta between two spending periods.

### Trend Summarization
The agent converts raw percentage shifts into readable text for your reports.

### Volatility Detection
Your agent identifies the most extreme spending spikes and drops in a dataset.

### Magnitude Categorization
The AI sorts growth rates into tiers to show how meaningful a change is.

## Use Cases

### Monthly Budget Reviews
Ask your agent to compare this month's utility costs against last month's to see the percentage shift.

### Expense Spike Detection
Run a batch analysis on a year of data to find which months had the highest spending growth.

### Reporting Automation
Have the AI generate a written summary of spending changes to paste directly into a slide deck.

### Cost Intensity Assessment
Use tier categorization to determine if a vendor price increase is minor or significant.

## Benefits

- Eliminates manual percentage math for budget comparisons.
- Converts raw numbers into descriptive text summaries.
- Identifies extreme spending fluctuations within large datasets.
- Categorizes cost changes into meaningful tiers.

## How It Works

Connecting this MCP to your AI client gives it immediate access to financial math tools.

1. Connect the MCP to your client through the Vinkius dashboard.
2. Provide your expense data or specific amounts to your AI agent.
3. The agent calls the necessary tool to calculate or categorize the change.
4. Receive the calculated rate, summary, or tier directly in your chat interface.

## Frequently Asked Questions

**What can this MCP do with my expense data?**
It calculates percentage growth, summarizes changes in text, categorizes the intensity of shifts, and finds extremes in historical data.

**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 the MCP and manages the connection for you.

**Can it handle multiple expense changes at once?**
Yes, the batch analysis tool allows your agent to evaluate multiple expense pairs in one go.

**How does it categorize growth?**
It uses a tiering mechanism to turn a raw percentage into a qualitative description of the change's magnitude.

**How do I calculate the growth rate?**
You can use the `get_growth_rate` tool by providing the base expense and the current expense.

**Can I analyze multiple expense changes at once?**
Yes, the `batch_growth_analysis` tool allows you to evaluate a list of historical expense pairs.

**What happens if the base expense is zero?**
The tools will return an error to prevent division by zero, as a base expense must be greater than zero.
