@AutoConfiguration @ConditionalOnClass(io.modelcontextprotocol.server.transport.WebFluxSseServerTransportProvider.class) @ConditionalOnMissingBean(io.modelcontextprotocol.spec.McpServerTransportProvider.class) @Conditional(McpServerStdioDisabledCondition.class) public class McpWebFluxServerAutoConfiguration extends Object
Auto-configuration for MCP WebFlux Server Transport.

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

  • The WebFluxSseServerTransportProvider class is on the classpath (from mcp-spring-webflux dependency)
  • Spring WebFlux's RouterFunction class is available (from spring-boot-starter-webflux)
  • The spring.ai.mcp.server.transport property is set to WEBFLUX

The configuration provides:

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