Interoperable Agent Discovery: AI Catalog, ARD, and the AGNTCY Directory

AGNTCon + MCPCon North America 2026

Oct 22, 2026 · 10:55–11:20 · America/Los_Angeles

Multi-agent systems today compose across MCP servers, A2A agents, and agent skills — artifacts that live in separate registries with incompatible metadata formats. AI Catalog addresses this at the standard level: a typed JSON format that gives each artifact type a common envelope for identity, capability, and provenance, without replacing the formats each community has standardized. What makes the standard operational is federation. AI Catalog's well-known discovery mechanism lets clients traverse distributed registries without a central index. ARD complements it with a user-facing API — enabling any code assistant (Claude, Copilot, Gemini) to discover AgentSkills, MCP servers, and A2A cards across federated catalogs, verify them cryptographically, and resolve them to a live endpoint without knowing the source registry. The AGNTCY directory is the reference implementation — content management, multi-registry discovery, and federation end to end. We demo the full flow: publishing an AgentSkill, an MCP server, and an A2A card under the AI Catalog standard, federating them through ARD, and discovering them securely from a code assistant at runtime.
