Building MCP servers with Spring AI: a practical boundary for agents

MCP becomes especially interesting when it connects AI agents to systems that already exist in enterprise applications. For Java teams, Spring AI is one practical way to build that bridge. Why build an MCP server? An MCP server exposes tools or data sources to AI clients through a shared protocol. Instead of wiring every AI client directly into your application, you can provide a controlled integration layer: AI client -> MCP server -> application logic or data source That layer can enforce boun
