This page details the example found in /examples/http/go-zero, demonstrating how to integrate the HTTP+SSE transport with the go-zero web framework.

go-zero Server (examples/http/go-zero)

This example shows how to mount the sse.Server and server.Server HTTP handlers onto a go-zero rest.Server.

Key parts:

package main

import (
	"flag"
	"log"
	"net/http"

	"github.com/zeromicro/go-zero/core/conf"
	"github.com/zeromicro/go-zero/rest"
	// ... other imports: server, protocol, types, sse ...
)

// Define go-zero config structure (if needed, often minimal for this)
type Config struct {
	rest.RestConf
}

func main() {
	// --- go-zero Config Loading ---
	var configFile = flag.String("f", "etc/config.yaml", "the config file") // go-zero convention
	flag.Parse()

	var c Config
	conf.MustLoad(*configFile, &c) // Load config (might just contain RestConf)

	// --- Setup MCP Server ---
	serverInfo := types.Implementation{Name: "go-zero-http-server", Version: "0.1.0"}
	opts := server.NewServerOptions(serverInfo)
	srv := server.NewServer(opts)
	// Register tools, etc.

	// --- Create SSE Transport Server ---
	sseServer := sse.NewServer(srv, opts.Logger)

	// --- Setup go-zero Server and Routes ---
	engine := rest.MustNewServer(c.RestConf)
	defer engine.Stop()

	// Mount standard http.Handlers directly
	engine.AddRoute(rest.Route{
		Method:  http.MethodGet,
		Path:    "/events",
		Handler: http.HandlerFunc(sseServer.HTTPHandler),
	})
	engine.AddRoute(rest.Route{
		Method:  http.MethodPost,
		Path:    "/message",
		Handler: http.HandlerFunc(srv.HTTPHandler),
	})

	// Add a root handler for testing
	engine.AddRoute(rest.Route{
		Method: http.MethodGet,
		Path:   "/",
		Handler: func(w http.ResponseWriter, r *http.Request) {
			w.Write([]byte("go-zero MCP Server running. Use /events and /message."))
		},
	})

	// --- Start go-zero Server ---
	log.Printf("Starting go-zero HTTP+SSE MCP server on %s:%d...", c.Host, c.Port)
	engine.Start() // Blocks until interrupted
}

(Note: This assumes a minimal etc/config.yaml exists for go-zero’s rest.RestConf, e.g., specifying Host and Port)

To Run: Navigate to examples/http/go-zero and run go run main.go -f etc/config.yaml. Clients connect as described in the net/http example (SSE to /events, POST to /message).

go-zero’s rest.Server allows adding routes with standard http.HandlerFunc handlers, making integration straightforward.
