go + vscode + cline +qwen 快速构建 MCP Server

go 编译自定义 mcp tool

current time tool 代码

package mainimport ("context""fmt""time""github.com/mark3labs/mcp-go/mcp""github.com/mark3labs/mcp-go/server"
)func main() {// Create MCP servers := server.NewMCPServer("Demo ?","1.0.0",)// Add tooltool := mcp.NewTool("current time",mcp.WithDescription("Get current time with timezone, Asia/Shanghai is default"),mcp.WithString("timezone",mcp.Required(),mcp.Description("current time timezone"),),)// Add tool handlers.AddTool(tool, currentTimeHandler)// Start the stdio serverif err := server.ServeStdio(s); err != nil {fmt.Printf("Server error: %v\n", err)}
}func currentTimeHandler(ctx context.Context, request mcp.CallToolRequest) (*mcp.CallToolResult, error) {timezone, ok := request.Params.Arguments["timezone"].(string)if !ok {return mcp.NewToolResultError("timezone must be a string"), nil}loc, err := time.LoadLocation(timezone)if err != nil {return mcp.NewToolResultError(fmt.Sprintf("parse timezone with error: %v", err)), nil}return mcp.NewToolResultText(fmt.Sprintf(`current time is %s`, time.Now().In(loc))), nil
}

编译

go build -o current-time-tool.exe .\current_time.go
