From SaaS to Agentic SaaS: How Navan Built Travel & Expense MCP Servers on AWS

Navan architects Roberto Milev and Uday Kanagala explain how Navan Anywhere brings travel and expense capabilities into the AI tools customers already use. They go inside Navan's production travel-agent MCP server for flight, hotel, and car search-and-book flows and its expense-agent MCP server for governed T&E intelligence. Built on Amazon Bedrock AgentCore Runtime, Gateway, and Memory, these services show how Navan delivers secure, multi-tenant agentic SaaS across 120+ microservices and 20 engineering teams.
