Exposes 24 tools wrapping U.S. personal finance data from Freddie Mac, FRED, BLS, and IRS via the CalcFi public CDN. You get mortgage rate lookups, paycheck tax withholding, CPI queries, debt payoff schedules, and macro series without API keys or signup. Every response includes source attribution, a methodology URL, and citation metadata in five academic formats. Ships with Python and Node installers that auto-configure Claude Desktop, Cursor, and Continue.dev. Runs stdio by default so nothing phones home except CDN pulls for fresh data. Reach for this when you need Claude to cite current mortgage rates or compare take-home pay across states without leaving the chat or scraping government sites yourself.
