Spring Ai Mcp Server Patterns

This gives you the patterns to build MCP servers with Spring AI, letting you expose tools and prompt templates that AI models can actually call. You get `@Tool` and `@PromptTemplate` annotations that work like standard Spring components, plus stdio/HTTP/SSE transport configuration for different client types. The skill covers the full stack: defining tool handlers with `@ToolParam` documentation, securing them with Spring Security, testing with MockBean, and handling the usual production concerns like caching and error handling. If you're already in the Spring ecosystem and want to extend Claude or other AI models with custom function calling, this is more natural than building raw MCP from scratch.
