Why immigration-mcp?

Navigating US immigration is complex and expensive. immigration-mcp gives AI agents access to live, structured immigration data from official government sources — so you can ask questions in plain English and get accurate, up-to-date answers.

• Free — powered by public government data sources (USCIS, State Department)
• Live data — fetches the latest Visa Bulletin monthly, USCIS news daily
• Open source — MIT licensed
• Production grade — structured logging, graceful shutdown, unit tested

Each tool is self-contained — the server is agnostic of what tools do internally. Adding a new tool is a single line in server/server.go.
