## Description

Managing cash flow means constantly choosing between reducing liabilities and maximizing liquid assets. This MCP gives your AI agent the math it needs to make those calls. Instead of guessing if a 2% discount is worth it, you can ask your agent to run the numbers against your current savings rate or investment yield. 

It handles the heavy lifting of normalizing one-time discounts into annualized percentages so you can compare them to standard interest rates. You can also see exactly how much interest you lose by paying a vendor early. It turns vague financial intuition into hard data, letting you decide if taking a discount actually grows your bottom line or if your cash is better spent staying in the market.

## Tools

## Prompt Examples

```
Should I take a 2% discount on a $10,000 invoice if I can pay it 15 days early, given my cash earns 5% annually?
