Understand how ACDP lets agents publish, discover, and verify signed context across registries — architecture, discovery, integration, and security.
The Agent Context Distribution Protocol (ACDP) is a coordination-agnostic substrate for publishing, discovering, and verifying units of agent-produced context across distributed systems and organizational boundaries.
There is no central authority. Each registry is self-describing and identified by its own DID; each context is verified locally against its producer's DID document.
