This MCP gives your AI client the ability to act as a precise financial analyst for home buying. Whether you are looking at a single loan or trying to decide between three different interest rates and down payment amounts, you can get clear, mathematical answers in seconds. You can use it to see how much total interest you'll pay over the life of a loan or to see if a specific property's taxes and HOA fees will push your monthly payment past your limit. If you have a strict monthly budget, you can ask the AI to work backward and tell you the exact down payment required to make the numbers work. It turns your agent into a dedicated mortgage calculator that understands the relationship between interest rates, term lengths, and upfront costs. ## Tools ### calculate_single_option This tool performs a deep dive into one specific mortgage scenario to show you the full cost breakdown. ### compare_loan_options Use this to rank multiple mortgage scenarios against each other based on your specific financial priorities. ### evaluate_affordability This tool checks if a loan fits within your defined monthly budget and available cash. ### find_optimal_down_payment This tool calculates the exact down payment you need to reach a specific target monthly payment. ## Prompt Examples **Prompt:** ``` Compare these two loans: Option 1 is $400,000 price, $80,000 down, 6% rate, 30 years, $300 taxes, $100 insurance, $50 HOA, $5,000 closing.
