## Description

You can stop relying on your AI client to guess at financial math. This MCP provides the exact logic needed to handle complex loan calculations without errors. When you ask your agent about a new loan, it uses these tools to pull specific installment amounts, check if your proposed terms actually make sense, and calculate exactly how much interest you'll pay over the life of the debt. It's built for anyone who needs to run quick, accurate financial scenarios through a chat interface. Whether you're checking a mortgage estimate or a small personal loan, your agent gets the math right every time.
