Example usage
Once connected, just ask Claude naturally:
"I'm looking at a $450,000 house with 20% down at 6.8% for 30 years. What's my monthly payment and total interest?"
"Compare a 15-year loan at 6.2% vs 30-year at 6.8% for $380,000. Which is better overall?"
"I spend $48,000/year. How much do I need to retire, and how long will it take if I save $24,000/year?"
"I have $8,500 in credit card debt at 22% APR. How long to pay it off at $250/month, and how much do I save if I add $100/month extra?"
Why this exists
Most finance calculators are either locked behind paywalls, require accounts, or are ad-stuffed websites. This MCP gives Claude direct access to accurate financial math — no API keys, no rate limits, no middleman.
