CalculatorsMCP

Calculators for you and your AI assistant.

Each calculator is a website you can open and an MCP server your assistant can call. Both run the same maths, so the answers match. One calculator so far, more on the way.

US auto loans

Monthly payment, total interest and what a car really costs.

Enter the price, down payment, trade-in, rate, term, sales tax and fees. See the monthly payment, the amount financed and the total cost, side by side for up to four scenarios.

Your AI assistant can do the same maths through the MCP: one loan, a comparison, the highest price for a monthly budget, or a yearly payoff table. Every answer links back to the same numbers on the site.
