Introducing the MCP Registry (blog.modelcontextprotocol.io)

The Model Context Protocol (MCP) Registry has officially launched in preview, offering an open catalog and API designed to enhance the discoverability and adoption of publicly available MCP servers. By standardizing how these servers are published and found, the registry acts as a centralized "single source of truth" for MCP server information, enabling easier connection for clients and expanding server reach within the AI ecosystem. This development is significant for the AI/ML community as it fosters a more interoperable and scalable infrastructure for context-aware AI services, facilitating smoother integrations and improved tooling support. Technically, the MCP Registry is open source and incorporates a parent OpenAPI specification, allowing anyone to create compatible sub-registries, whether public marketplaces tailored to different use cases or private enterprise registries with strict security requirements. This flexibility ensures the ecosystem can grow organically without undermining existing registries. Furthermore, the registry includes community-driven moderation to maintain quality and security by filtering out spam or malicious entries. While currently in preview and subject to changes before general release, the MCP Registry represents a foundational step toward a standardized, collaborative platform supporting more reliable AI applications worldwide.
