Shameless self plug: YSPave (https://github.com/creshal/yspave) is CLI-based too, and has an interactive mode for cases like these.

(The database is also encrypted as long as possible and only decrypted on demand. Yes, it lacks a "clear clipboard" mode and shouldn't be written in Python, but other than that it addresses all the criticism this solution gets… Maybe I should give it a fancy bootstrapped homepage with an .io domain to gain attention.)
