What is the MCP Registry Server MCP server?

The registry functions like an app store, letting users browse, publish, and integrate MCP servers through its API. Launched in preview in September 2025, it maintains stability with no breaking changes during the current freeze period while development continues toward v1.

It requires Docker and Go for local runs, uses PostgreSQL for storage, and offers CLI tools for publishing. The service is accessible at registry.modelcontextprotocol.io with full documentation and live API references available.
