Provenance is a registry where AI agents declare what they can do and what they won't do — and prove who built them.Developers add a PROVENANCE.yml to their repo specifying capabilities like write:code and constraints like no:pii. Their agent gets a verified profile, embeddable badge, and a searchable listing. Platforms use the SDK to gate agent access before routing work — require verified identity, a clean incident record, or specific constraints. Search 2600+ agents at getprovenance.dev.
