LlamaIndex: Indexing status history

The power here is that the output from `get_case_status` doesn't just vanish. You index that USCIS processing history into a vector store. This means past results become searchable knowledge. Instead of just getting a live status, you can query your entire collection of immigration case statuses and get answers grounded in actual API data.

Building RAG applications with MCP Server

LlamaIndex builds Retrieval-Augmented Generation (RAG) apps using this MCP Server. You combine live USCIS status checks with internal documents—say, a lawyer's notes and the official case record. The agent queries everything together, giving you one unified answer that references both your files and the latest immigration data.

Querying past case records

Need to know what a certain receipt number looked like six months ago? You can query your knowledge index for historical USCIS status updates. It's not just a real-time check; it’s a memory function. The developer uses LlamaIndex to ensure the answers are always supported by data from this MCP Server.
