Sometimes a developer or analyst needs to see SQL Agent jobs or its history.
Create a login, add to role, open SSMS and log in as that login which has no other permissions, and view jobs, check history, and notice everything is grayed out.
CREATE LOGIN jperryx WITH PASSWORD = '1anGxxp22' USE [msdb] GO CREATE USER [jperryx] FOR LOGIN [jperryx] ALTER ROLE [SQLAgentReaderRole] ADD MEMBER [jperryx] GO
After testing yourself, and knowing what they can do with this access, you can decide if you should grant it or not.
You can find more about it here.
Now clean up.
DROP USER jperryx GO DROP LOGIN jperryx GO
