public class MpcWebMvcServerAutoConfiguration
extends Object

Auto-configuration for MCP WebMvc Server Transport.

This configuration class sets up the WebMvc-specific transport components for the MCP server, providing Server-Sent Events (SSE) communication through Spring MVC. It is activated when:

• The WebMvcSseServerTransport class is on the classpath (from mcp-spring-webmvc dependency)
• Spring MVC's RouterFunction class is available (from spring-boot-starter-web)
• The spring.ai.mcp.server.transport property is set to WEBMVC

The configuration provides:

• A WebMvcSseServerTransport bean for handling SSE communication
• A RouterFunction bean that sets up the SSE endpoint

Required dependencies:

 <dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-web</artifactId>
 </dependency>
