The new **Model Context Protocol (MCP) Registry** just dropped in preview. It’s a public, centralized hub for finding and sharing MCP servers—think phonebook, but for AI context APIs. It handles public and private subregistries, publishes OpenAPI specs so tooling can play nice, and bakes in community-driven moderation with flagging and denylists. **System shift:** This locks in a new standard. MCP infrastructure now has a common ground for discovery, queries, and federation across the stack.
