Class McpChannelInitializer

java.lang.Object
io.netty.channel.ChannelHandlerAdapter
io.netty.channel.ChannelInboundHandlerAdapter
io.netty.channel.ChannelInitializer<io.netty.channel.socket.SocketChannel>
dev.tachyonmcp.core.transport.netty.McpChannelInitializer
All Implemented Interfaces:
io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler
@Sharable public class McpChannelInitializer extends io.netty.channel.ChannelInitializer<io.netty.channel.socket.SocketChannel>
Assembles the Netty pipeline for each new MCP channel: validation handlers (endpoint, origin, protocol version, accept header, stateless guard), InteractionHandler, HTTP aggregation, idle timeout, the initialization-phase handler (McpInitializationHandler), and the LifecyclePipelineCoordinator.

In stateless mode, StatelessValidatorHandler is added to reject session-related headers and DELETE methods before they reach protocol handlers.
