Building an MCP Server Using Spring AI, JSON-RPC and SSE (Server-Sent Events)

Introduction: Modern LLM-powered applications require external tools to interact with real-systems such as a databases, APIs, cloud platforms, and enterprise services. MCP (Model context Protocol) provides standardized mechanism for exposing tools to AI agents. In this article, we will build an MCP Server using Spring AI with SSE( Server-Sent Events) transport support. We will also understand how JSON-RPC and Server-Sent Events work together to enable asynchronous communication between AI agent...
