Perplexity

Create RAG applications with the MCP Server

When you run `get_income_by_county`, the output becomes indexed into your vector store. This means that live county median income and poverty data are now part of a searchable knowledge base, not just a temporary API call. Your LlamaIndex application can then answer complex questions like, 'Which counties near this zip code have high payroll but low educational attainment?' by querying the index.

Index state education data with LlamaIndex

Need to search past economic reports? You index `get_education_by_state` results. This lets your agent retrieve historical knowledge about which states had high educational attainment versus their median income levels, grounding answers in actual API data. It removes the risk of hallucination because every piece of information is traceable back to the Census source.

Search business patterns via LlamaIndex

You can feed `get_business_patterns` results into your index. This makes local economic activity—like payroll counts and establishment numbers—semantically searchable. You're not just running a query; you're asking the knowledge base to find connections. This is crucial for combining business data with other documents in a unified, queryable index.
