Introducing the MCP Registry
Today, we’re launching the Model Context Protocol (MCP) Registry—an open catalog and API for publicly available MCP servers to improve discoverability and implementation. By standardizing how servers are distributed and discovered, we’re expanding their reach while making it easier for clients to get connected. The MCP Registry is now available in preview. To get started: Add your server by following our guide on Adding Servers to the MCP Registry (for server maintainers) Access server data by following our guide on Accessing MCP Registry Data (for client maintainers) Single source of truth for MCP serversIn March 2025, we shared that we wanted to build a central registry for the MCP ecosystem. Today we are announcing that we’ve launched https://registry.modelcontextprotocol.io as the official MCP Registry. As part of the MCP project, the MCP Registry, as well as a parent OpenAPI specification, are open source—allowing everyone to build a compatible sub-registry.

Model Context Protocol (MCP): A New Standard for AI Application and External Data Integration
The Model Context Protocol (MCP) introduced by Claude in late 2024 has quickly gained widespread attention and recognition from developers and the community. As a developer who has been involved in several small AI projects over the past year, I deeply understand the challenges of integrating AI models into existing systems or third-party services. The emergence of MCP comes at the perfect time, not only solving these pain points but also bringing a vision of an open, standardized ecosystem. Below, I’ll analyze why it has been widely accepted from a developer’s perspective, combining MCP’s working principles and advantages.
