From Monolith to AI Agent: Modernizing Java Systems with MCP

Many Java systems power critical enterprise workflows but struggle to integrate with modern AI capabilities without expensive rewrites. The Model Context Protocol offers a new integration path by letting your existing Java services talk to LLMs as first-class citizens.

This talk walks you through refactoring a legacy Java application into an AI-enabled agent using MCP. We’ll cover practical patterns for exposing services, handling tool calls, and streaming results plus strategies for controlling and auditing AI actions in production. You’ll see how MCP lets Java stay relevant in the fast-moving AI ecosystem without sacrificing stability.
