日期：2025-03-27点击：21收藏

Model Context Protocol (MCP) 的 Go 实现，实现 LLM 应用程序与外部数据源和工具之间的无缝集成。

package main import ( "context" "errors" "fmt" "github.com/mark3labs/mcp-go/mcp" "github.com/mark3labs/mcp-go/server" ) func main() { // Create MCP server s := server.NewMCPServer( "Demo 🚀", "1.0.0", ) // Add tool tool := mcp.NewTool("hello_world", mcp.WithDescription("Say hello to someone"), mcp.WithString("name", mcp.Required(), mcp.Description("Name of the person to greet"), ), ) // Add tool handler s.AddTool(tool, helloHandler) // Start the stdio server if err := server.ServeStdio(s); err != nil { fmt.Printf("Server error: %v\n", err) } } func helloHandler(ctx context.Context, request mcp.CallToolRequest) (*mcp.CallToolResult, error) { name, ok := request.Params.Arguments["name"].(string) if !ok { return nil, errors.New("name must be a string") } return mcp.NewToolResultText(fmt.Sprintf("Hello, %s!", name)), nil }
