Agent Authorization and Consent: Who Decides What an Agent Can Do

Agent authorization defines who has the legal and operational authority to grant an AI agent permission to take specific actions — and consent defines what the people affected by those actions have agreed to — together forming the governance framework that makes agent autonomy safe and legitimate.

Authorization and consent are the legal and ethical foundations beneath all technical safety mechanisms. An agent that has excellent logging, perfect auditability, and reliable override mechanisms is still acting improperly if it is taking actions that its operator did not authorize or that the affected parties did not consent to. The technical infrastructure serves the authorization and consent framework; it does not replace it.

The Authorization Chain

Every agent action can be traced back through an authorization chain: who authorized the agent to take this type of action, under what conditions, with what limits, and with what accountability. A complete authorization chain has no gaps — there is no point at which someone simply assumed the authorization was in place without explicitly granting it.

The authorization chain for a typical agent deployment runs: platform operator authorizes the agent owner to deploy agents with certain capabilities on the platform. Agent owner authorizes the agent to act within a defined scope. Agent operates within that scope, escalating when it encounters situations outside it. Any action the agent takes that is not within the scope authorized by the agent owner — and approved by the platform operator's policies — is unauthorized.

Authorization chains have two important properties. First, they are bounded: no one in the chain can grant more authority than they themselves have. An agent owner cannot authorize the agent to access data the owner does not have the right to access. A platform cannot grant agent capabilities that violate applicable law. Second, they are non-transferable without explicit re-authorization: an agent cannot pass its authorization to another agent or expand its own authorization without going back up the chain.

Scope Definition: The Core of Authorization

The scope of an authorization defines exactly what the agent is permitted to do. Scope has four dimensions that should all be specified explicitly:

All four dimensions should be specified in every authorization grant. Authorizations that omit any dimension effectively grant unlimited scope in that dimension, which creates the gaps that scope creep exploits. Complete scope specification is the primary tool for preventing authorization creep over time.

Consent: The Affected Party Dimension

Authorization addresses who has the authority to permit agent actions. Consent addresses whether the people those actions affect have agreed. These are distinct questions with different answers in different contexts.

When an agent acts on behalf of a user — managing their schedule, processing their documents, communicating with their contacts — the user whose data is being processed must have consented to that specific use. General terms of service consent that covers 'all data processing' may be legally sufficient in some jurisdictions but is not sufficient for high-stakes or sensitive data processing. Meaningful consent is specific to the processing purpose and the type of data involved.

When an agent interacts with third parties on behalf of its owner — contacting potential customers, processing applications, making purchase decisions — the third parties have not necessarily consented to interacting with an agent rather than a human. The obligation to disclose that the interaction is with an AI agent, rather than a person, is an emerging legal requirement in several jurisdictions and a clear ethical obligation regardless of legal requirement.

Consent Withdrawal and Authorization Revocation

Consent and authorization must both be revocable. A user who withdraws consent for a specific type of data processing must be able to do so without requiring the agent owner's cooperation. An agent owner who revokes a previously granted authorization must have a mechanism for the revocation to take effect promptly — including on agent sessions that are currently running.

Revocation architecture is a technical requirement that many agent deployments underinvest in. It is significantly easier to build authorization grants than to build authorization revocations that take effect reliably across all operational contexts. This asymmetry creates deployments where agents technically continue to operate with permissions that have been revoked, because the revocation mechanism was not tested or maintained with the same rigor as the grant mechanism.
