Agent Registry
An agent registry is a central directory or metadata store where AI agents and their capabilities (tools, resources, prompts) are registered, allowing for discovery, version management, and orchestration by the host.
In complex multi-agent systems, agents need to find each other dynamically. A registry provides the lookup service: an orchestrator queries the registry to find the correct agent to handle a specific task (e.g., "find the agent capable of CI test execution"). Registries often include health status, tool descriptions, and auth requirements.
