Definitions

The AGNTCY supports various types of identities, referred to as IDs, which serve as universally unique identifiers for the main entities or subjects operated by the AGNTCY, including Agents, MCP Servers, and Multi-Agent Systems (MASs).

Key Identifiers

Each ID is associated 1:1 with ResolverMetadata, which contains the necessary information to establish trust while trying to use or interact with an Agent, an MCP Server, or a MAS ID.

• ID: A universally unique identifier that represents the identity of a subject.

• ResolverMetadata: Metadata, represented in the form of a JSON-LD object, containing cryptographic material and assertion methods enabling to automatically resolve and establish trust with the associated ID (e.g., an Agent, an MCP Server, or a MAS).

Concrete examples with various IDs and associated ResolverMetadata can be found here.
