 !!! tip
     The core `io.modelcontextprotocol.sdk:mcp` module provides default STDIO, SSE, and Streamable HTTP client and server transport implementations without requiring external web frameworks.
 
-    Spring-specific transports are available as optional dependencies for convenience when using the [Spring Framework](https://docs.spring.io/spring-ai/reference/api/mcp/mcp-client-boot-starter-docs.html).
