FAQ from CalcFi MCP

Does CalcFi MCP require an API key?

No. All tools are free and work without any API keys or signup. The server uses public financial data updated daily.

What data sources power the calculations?

Every tool references primary sources: IRS publications, Federal Reserve Economic Data (FRED), BLS tables, Treasury yield curves, Census ACS, HUD FMR, and Freddie Mac PMMS.

How is CalcFi MCP different from an LLM answering financial questions?

All calculations are deterministic and run in code, not predicted by the model. Outputs include the specific source reference, eliminating hallucinated tax brackets or mortgage rates.
