Treasury Fiscaldata Mcp Server

Connects Claude to the US Treasury's Fiscal Data API with seven tools covering 80+ datasets. The main workhorse is a generic query builder that takes filters, sorts, and pagination for any endpoint. Three convenience tools handle the most common asks: national debt since 1993, average interest rates on Treasury securities, and statutory exchange rates for 130 countries. Results can spill into DuckDB backed DataCanvas dataframes, letting you run SQL joins and aggregates across multiple queries in the same conversation. Ships with an embedded catalog so you can browse available endpoints without hitting the network. Built on the mcp-ts-core framework with both STDIO and streamable HTTP transports.
