Microsoft Defender EDR for old Windows Server 2008/2012/2016

Microsoft documentation states EDR feature is supported on older windows server versions like Server 2012/2016. Then it goes on to say to deploy the MMA agent. But, isn't MMA agent just a read-only log analytics agent that can only report the status of the server but can take no action. 

Hence, EDR means only detection but no response. Am I correct in understanding that? We are evaluating Defender for Servers and have gone through quite a lot of documentation but still no definitive answer.
