The framework offers three core annotations: @McpTool for exposing Java methods as AI-callable functions, @McpResource for providing read-only data access via URI templates, and @McpPrompt for defining reusable prompt templates. The implementation uses standard Spring patterns with POJOs and Records, supports complex objects and binary data, and communicates via Standard Input/Output when running locally. Configuration requires adding Spring Milestone/Snapshot repositories, the spring-ai-starter-mcp-server dependency, and specific application properties to disable console logging for proper protocol communication. ## Full article daily.dev links to this article rather than hosting it.
