Agent Registry
Definition
A directory or catalog that lists available agents with their capabilities, interfaces, trust properties, and operational metadata. Unlike a marketplace (which facilitates transactions), a registry facilitates discovery — helping developers and other agents find the right agent for a task. Registries typically include: capability descriptions, supported protocols (MCP, A2A), authentication requirements, SLA information, and trust/quality scores. Agentifact itself functions as an agent registry for the developer ecosystem.
Builder Context
As the agent ecosystem grows, discoverability becomes a real problem. Register your agents and tools in relevant directories — it's the equivalent of submitting your API to a public directory. For your own agent systems: maintain an internal registry of available tools and agents with capability descriptions, so orchestrating agents can discover and select the right resources dynamically rather than being hardcoded.
