Indexing Historical Debt with LlamaIndex

When you run `get_debt_history`, the output isn't just a temporary answer—LlamaIndex indexes it. You can create a searchable knowledge base containing records of national debt across different fiscal years, allowing you to query past sessions or documents against this timeline. This means your RAG application doesn't hallucinate; it grounds answers in actual data points pulled from the `get_debt_history` tool output.

Creating a Knowledge Graph of Debt Components with LlamaIndex

The MCP Server lets you pull highly granular information, like the full Statement of Public Debt using `get_public_debt_breakdown`. Indexing this detailed breakdown means anyone can query complex relationships—for example, 'How has intragovernmental debt changed relative to marketable securities?' It turns raw data into a unified, retrievable index, making the entire history of U.S. Treasury Debt searchable.

Searching Auction Results with LlamaIndex

Need context on why current debt levels are stable? Use `get_treasury_auctions` to get recent bid-to-cover ratios, and then index that result. Later queries can combine this fresh auction data with internal documents about market stability. LlamaIndex makes sure the latest investor demand figures aren't forgotten; they become part of your persistent, queryable knowledge base.
