Which shell do you use? The legacy mongo shell (I prefer term "classic shell") or the new mongosh?

In the new mongosh, it is easy. The mongosh is a Node.js shell, simply use process.env

In legacy shell mongo you can use undocumented function _getEnv() or you pass environment variable in --eval, for example

mongo --eval "var my_var = '$MY_VAR';" ...

See How to pass environment variable to mongo script
