Personal Agent Consent & Trust Protocol (PACT)
The Personal Agent Consent & Trust Protocol (PACT) is an open-source standard designed to facilitate secure, verifiable interactions between customer-facing personal AI agents and business-side AI agents. By leveraging OAuth 2.0 and the Agent2Agent (A2A) protocol, PACT allows businesses to authenticate personal agents and manage customer-granted permissions without exposing sensitive login credentials.
