Overview
The Mortgage Calc MCP server performs exact mortgage and loan computations, delivering amortization schedules, refinance comparisons, affordability analysis, and debt-to-income (DTI) ratios with decimal-accurate precision. It supports programmatic access for embedding financial math into applications without manual spreadsheets or approximations.
Key Capabilities
- amortization_schedule: Outputs a full payment breakdown by period, tracking principal reduction, interest accrual, and remaining balance over the loan term.
- refinance_comparison: Evaluates existing loans against new terms, computing total interest savings, monthly payment changes, and break-even timelines.
- affordability_analysis: Calculates maximum borrowable amounts based on user income, down payment, interest rates, and property taxes.
- dti_ratio: Determines debt-to-income percentages from monthly debts and gross income, aiding loan qualification checks.
These functions use high-precision arithmetic to avoid rounding errors common in standard floating-point calculations.
Use Cases
- Fintech App Integration: A loan origination platform calls amortization_schedule and dti_ratio to pre-qualify applicants during onboarding, displaying customized schedules.
- Real Estate Tools: An agent dashboard uses refinance_comparison to show clients potential savings from rate drops, factoring in closing costs.
- Personal Finance Apps: Users input scenarios into affordability_analysis to test home purchase feasibility under varying rates and incomes.
- Compliance Reporting: Financial institutions run dti_ratio batches for portfolio risk assessment and regulatory filings.
