if (name === "list_target_groups") { const lbArn = (args as any)?.load_balancer_arn; const command = new DescribeTargetGroupsCommand(lbArn ? { LoadBalancerArn: lbArn } : {}); const response = await elbv2Client.send(command); const tgs = response.TargetGroups?.map(tg => ({ TargetGroupName: tg.TargetGroupName, Protocol: tg.Protocol, Port: tg.Port, TargetType: tg.TargetType, TargetGroupArn: tg.TargetGroupArn, LoadBalancerArns: tg.LoadBalancerArns })) || []; return { content: [{ type: "text", text: JSON.stringify(tgs, null, 2) }] }; } - src/index.ts:565-577 (registration)Tool registration in the ListTools handler, defining the tool name, description, and input schema for 'list_target_groups'.
