I connect Claude to your own Oracle Cloud EPM pod and help the people who run EPM check jobs, run rules, load data and read metadata or a slice of numbers. Each person connects as themselves, so Oracle applies their own roles. I encrypt credentials on my server; they never reach Claude. Every call passes a policy check and is logged. Risky writes ask for confirmation first, with a preview of what will change. On a production pod that is every write. The activity log holds no cell values.
