LlamaIndex Knowledge-Augmented Finance

You can index the results of `get_national_debt` directly into your vector store. Instead of just getting a number, you build a searchable knowledge base that answers questions like: 'How has the national debt changed since 2016?' The output from this MCP Server becomes part of your RAG corpus, allowing users to query past sessions or configurations grounded in actual Treasury data, eliminating hallucinations.

MCP Server Spending and Revenue Indexing

LlamaIndex lets you capture the results of `get_federal_revenue` and `get_federal_spending`. You index these documents to allow users to search across fiscal years. Users can query historical spending by department or current revenue sources, all within one unified index. This means your AI client doesn't just answer with a number; it provides context, linking the expenditure data (`get_federal_spending`) to its source and timing.

LlamaIndex Treasury Rate Comparison

Use `get_treasury_exchange_rates` to get official rate history for 170+ currencies. LlamaIndex indexes these rates so you can query specific historical comparisons, such as 'What was the USD/YEN exchange rate in Q4 of last year?' This is better than just calling a tool; it allows users to search through massive datasets and retrieve contextual answers based on official government accounting data.
