Publicfinance

Public Finance MCP Server — SEC EDGAR filings, US Treasury rates, BLS labor statistics, and economic indicators in one MCP server. Zero API keys required.

npm version License: MIT

Why This Exists

Existing SEC EDGAR MCP servers only cover filings. Existing FRED servers require API keys. No MCP server combines SEC EDGAR + US Treasury rates + BLS labor stats into one unified interface with zero configuration.

PublicFinance MCP gives AI agents access to the entire US public financial data landscape — company filings, yield curves, unemployment data, CPI, and more — all from free government APIs.
