Why it matters
Over-provisioning AI agents with broad bearer credentials creates excessive-agency and data-exfiltration risk, so defenders need to understand why scoped, delegated authority matters when wiring agents to APIs.
An explainer by "Fact, fries & fomo with Anuj" argues that handing an AI agent a bearer credential (API key, OAuth token, or JWT) is not the same as granting scoped authority, because whoever holds the credential gets the access with no relationship defining who may act, for whom, and within what limits. The piece discusses non-human identities, delegation, and identity frameworks (e.g. DIDs) as approaches to constraining agent authority.
