public class SseHttpClientTransportAutoConfiguration
extends Object

Auto-configuration for Server-Sent Events (SSE) HTTP client transport in the Model Context Protocol (MCP).

This configuration class sets up the necessary beans for SSE-based HTTP client transport when WebFlux is not available. It provides HTTP client-based SSE transport implementation for MCP client communication.

The configuration is activated after the WebFlux SSE transport auto-configuration to ensure proper fallback behavior when WebFlux is not available.

Key features:

• Creates HTTP client-based SSE transports for configured MCP server connections
• Configures ObjectMapper for JSON serialization/deserialization
• Supports multiple named server connections with different URLs

• HttpClientSseClientTransport
• McpSseClientProperties

mcpHttpClientTransports

@Bean
public List<NamedClientMcpTransport> mcpHttpClientTransports(McpSseClientProperties sseProperties,
 org.springframework.beans.factory.ObjectProvider<com.fasterxml.jackson.databind.ObjectMapper> objectMapperProvider)

Creates a list of HTTP client-based SSE transports for MCP communication.

Each transport is configured with:

• A new HttpClient instance
• Server URL from properties
• ObjectMapper for JSON processing

Parameters:

sseProperties - the SSE client properties containing server configurations

objectMapperProvider - the provider for ObjectMapper or a new instance if not available

Returns:

list of named MCP transports
