What models, MCPs, and rules do you use for audit?

Hey everyone! Right now, I’ve developed a project completely from scratch with zero coding knowledge, using the VibeCode trend and Cursor. It works fine for now (at least functionally), but I’m not sure how secure it is in terms of auditing. I’d like to turn it into a project with a strong audit profile. What kind of solutions or approaches do you follow for audits (MCPs, models, rules, docs, etc.)? Any recommendations?”**
