Our AI agents have write access to everything. How do I enforce least privilege for autonomous agents?

The over-permissioned agent is the root cause of nearly every major AI production incident. Developers give agents broad API tokens, full database write access, and account-level credentials because it's faster than implementing scoped permissions. The result: agents with the keys to the kingdom and zero governance.

In the PocketOS incident, the agent found a Railway API token with account-level permissions — no scope restrictions, no destructive-operation confirmations. In 9 seconds, it deleted the production database and all backups.

Traditional approaches fail because they operate at the wrong layer. IAM controls who can access the connection. API gateways control rate limits. Neither controls what the agent does inside an authenticated session.

Exogram enforces least privilege at the action level, not the connection level. Even if an agent has valid database credentials, Exogram evaluates every individual query against deterministic policy rules. A SELECT passes. A DROP TABLE is blocked. A bulk DELETE requires explicit policy authorization. The blast radius of an over-permissioned agent drops from "your entire company" to zero — because Exogram governs what the agent does, not just what it can access.
