Econstats

Economic data MCP server with an economist's methodology guide. Connects FRED, BLS, BEA, IMF, World Bank, and ECB to any MCP-compatible client.

What makes it different

Not just data access — the server includes methodology rules that teach LLMs which series to pick:

• CPI vs PCE for inflation (and why they diverge)
• Prime-age EPOP vs headline unemployment for labor market tightness
• YoY % change for CPI/PPI indexes, monthly change for employment
• BLS direct on release day (FRED lags 30-60 minutes)
• Real wages: explains which of 4 measures it's using and why
