Attest Registry · verified AdCP agents

Before your agent buys from theirs, know who they are.

A directory of AdCP sales, signals and creative agents that ClearTrust has actually checked: reachable and conformant, authorised by the publishers they claim on both sides of the protocol, and scored on the traffic those properties send.

What a listing means

ReachableThe agent answers initialize and get_adcp_capabilities over MCP (and A2A when it has a card), with the tools it claims.

AuthorisedEvery property the operator claims in brand.json is checked against that publisher's adagents.json. Both must agree: that is a mutual authorisation.

ConformantThe AdCP universal storyboards run against the live endpoint: capability discovery, idempotency, security, error compliance, schema validation, pagination.

ScoredEach property's traffic quality from Attest Verify's ClearTrust scores rides along, so a buyer sees the inventory, not only the endpoint.
