使用golang调用高德mcp server

使用golang 调用高德mcp server

使用go语言mcp客户端调用高德mcp server。先去高德开发者后台申请apikey并设置高德mcp api key环境变量AMAP_API_KEY

package main

import (
	"context"
	"fmt"
	"log"
	"os"
	"encoding/json"
	"github.com/joho/godotenv"
	"github.com/modelcontextprotocol/go-sdk/mcp"
)

func main() {
	ctx := context.Background()

	godotenv.Load()
	apiKey := os.Getenv("AMAP_API_KEY")
	client := mcp.NewClient(&mcp.Implementation{Name: "mcp-client", Version: "v1.0.0"}, nil)

	ampURL := fmt.Sprintf("https://mcp.amap.com/mcp?key=%s", apiKey)
	log.Println("ampURL:", ampURL)
	transport := &mcp.StreamableClientTransport{Endpoint: ampURL}
	session, err := client.Connect(ctx, transport, nil)
	if err != nil {
		log.Fatal(err)
	}
	defer session.Close()

	// 查询mcp tools 列表
	tools, err := session.ListTools(ctx, &mcp.ListToolsParams{})
	if err != nil {
		log.Fatalf("ListTools failed: %v", err)
	}
	if tools == nil {
		log.Fatal("no tools")
	}
	
	for _, tool := range tools.Tools {
		PrintJson(tool)
	}

	// 调用mcp tools
	params := &mcp.CallToolParams{
		Name:      "maps_geo",
		Arguments: map[string]any{"address": "杭州市市民中心","city":"杭州"},
	}
	res, err := session.CallTool(ctx, params)
	if err != nil {
		log.Fatalf("CallTool failed: %v", err)
	}
	if res == nil {
		log.Fatal("CallTool no result")
	}
	PrintJson(res)
	for _, c := range res.Content {
		log.Print(c.(*mcp.TextContent).Text)
	}
}

func PrintJson(v any) {
	jsonRaw, _ := json.Marshal(v)
	log.Printf("%s\n", string(jsonRaw))
}

执行结果如下：
