There are several possible solutions.

(a) Local utilities do know about the DB. zapi.getParent(utility)

(b) If you rely on the context, then your utility API should incorporate this 
in the methods, i.e. utility.method(context, ...)

(c) Use zope.app.component.hooks.getSite() you can get the current site.

I only find solution (b) desirable.
