"Software as a service" is a well understood concept, and on the strength of that understanding, the SSPL is clear. (Although as with all things there are edge cases, there aren't more edge cases with the SSPL than with other licenses.) If your web app uses MongoDB (or any SSPL licensed software) to provide a value that is not substantially MongoDB itself, you are not making the software available as a service. If your code facilitates making MongoDB's features available to other users, you are providing MongoDB as a service and are obligated to make all that code available under the SSPL.
