Mappings

These guides describe how the AI Catalog logical format maps to specific distribution substrates and ecosystem artifact formats. They are informative — not part of the normative specification.

• Distribution Substrates — binding invariants for packing/unpacking catalogs across substrates
• OCI Distribution — content-addressed storage and signing via OCI registries
• xRegistry — hierarchical registry model with versioning and cross-referencing
• MCP Servers — discovering remote MCP servers via Server Cards
• Claude Code Plugins Marketplace — mapping the Anthropic marketplace format
