If you’ve ever asked, “Which agent actually made this change?” and realized your logs only say service-account-prod or automation-bot , you’ve already hit the core problem with autonomous AI systems: they can act, but they’re often not individually accountable. That gets painful fast. An agent opens a PR, rotates a secret, calls an internal MCP tool, or triggers a deploy. Later, you need to answer basic audit questions: Which agent performed the action? Under whose authority was it operating? Was it delegated access, and by whom? What exact policy allowed the action? Can I prove the event log wasn’t tampered with?
