Building Intelligent Java Apps: Agent Patterns, MCP, and the Future of AI Native

\ Note special location for this event: the IBM offices at 16 York Street, on the 7th Floor.\ Doors open at 6:00. Theresa Mammarella will be on site to sign guests in. The talk will start at 6:30. Topic Building Intelligent Java Apps: Agent Patterns, MCP, and the Future of AI Native Design As AI rapidly evolves from model experimentation to production-grade applications, Java developers are increasingly faced with a new paradigm: designing intelligent systems that can reason, interact, and adapt. This talk explores the emerging Java AI application development journey through the lens of agent-based architecture, with a focus on how the Model Context Protocol (MCP) and Agent2Agent (A2A) communication patterns are transforming the way we build intelligent, context-aware services. We’ll walk through the foundational shifts in building AI-native Java applications—moving beyond single-shot prompt-response interactions to multiagent coordination, persistent memory, and tool-augmented reasoning. We’ll also address the critical architectural trade-offs: performance versus flexibility, open source versus vendor-managed inference, local versus remote model deployment, and how to maintain security and observability in agent-based systems.
