Track Debt History using the MCP Server

The `get_debt_history` tool lets Cascade track how national debt has grown over specific time periods. Just tell it a date range—like 'the last two election cycles' or 'since 2008'—and it figures out the exact data needed. It maps out the total public debt for that span, letting you visualize growth patterns without having to prompt for every single year.

Get Treasury Auction Results with MCP Server

When `get_treasury_auctions` runs, Cascade pulls in results for Bills, Notes, and Bonds. You don't just get the prices; you get the bid-to-cover ratio. This number shows how much demand investors have for U.S. debt. If that ratio is high, it means strong investor confidence. Windsurf can use this data point to predict market sentiment.

Break Down Public Debt Components

Need to know where the money goes? Use `get_public_debt_breakdown` and Cascade handles the complexity. It gives you two distinct figures: Debt Held by the Public and Intragovernmental Holdings. This separation is critical for understanding who actually holds the debt—market investors or internal trust funds like Social Security.
