Searchable visitor history in LlamaIndex

Use `happierleads_info` to pull raw firmographic data and inject it into your vector store. Your index now contains live insights on who is browsing your site. This grounds your agent's knowledge in real-time activity. Instead of relying on stale CRM records, your agent queries the most recent visitor fingerprints.

Ground agent answers in actual API data

When your agent needs to know which companies visited today, it queries the index built from `happierleads_info` outputs. This cuts down on hallucinations by using hard data. Your agent doesn't guess. It looks at the index to confirm if a specific company has shown interest, then uses that context to draft a response.

Build RAG apps with live sales signals

Combine your internal documents with the data retrieved by this MCP Server. Your agent can compare current visitor intent against your historical sales documentation. It creates a unified view. You get a system that understands both your product and the specific companies currently evaluating your site.
