# MCP Server - Spring AI 2.0 and Java SDK 2.x Prefer Spring AI's MCP server starters and native annotations in Spring Boot applications. Use the standalone SDK only when Spring integration is intentionally not required. ## Dependencies Let the Spring AI BOM manage every Spring AI and MCP transitive dependency. Do not override its MCP SDK version independently. ```xml <!-- Pick exactly one transport starter. --> <dependency> <groupId>org.springframework.ai</groupId> <artifactId>spring-ai-starter-mcp-server</artifactId> </dependency> <!-- Remote MVC: spring-ai-starter-mcp-server-webmvc --> <!-- Remote reactive: spring-ai-starter-mcp-server-webflux --> ``` For an application that uses the raw SDK without Spring AI, use the current 2.x release and follow its 2.0 migration guide. MCP Java SDK 2.0 tracks the 2025-11-25 protocol and prefers Streamable HTTP; SSE transports are deprecated. ```xml <dependency> <groupId>io.modelcontextprotocol.sdk</groupId> <artifactId>mcp</artifactId> <version>2.0.0</version> </dependency> ``` ## Native Spring AI MCP tools Use `@McpTool` and `@McpToolParam` for server capabilities. `@Tool` is Spring AI's model tool-calling API; it is not the native MCP server annotation. ```java @Component final class OrderMcpTools { private final OrderService orderService; OrderMcpTools(OrderService orderService) { this.orderService = orderService; } @McpTool( name = "get_order", description = "Get...
