Introducing the MCP Registry

"MCP gives IDEs and agents a standard way to talk to tools and data. As the docs put it, "Think of MCP like a USB-C port for AI applications," which captures the goal of uniform connectors with minimal client glue. The registry sits above that protocol, publishing a machine-readable catalog of servers that clients can query and install. "We're launching...the MCP Registry-an open catalog and API for publicly available MCP servers," the maintainers wrote in the preview announcement."

"The preview emphasizes federated discovery rather than a single walled list. The team describes the official service as a "primary source of truth" that public marketplaces and private enterprise sub-registries can mirror and extend, all against a shared OpenAPI. There's a moderation process (including deny-listing) and, for now, a clear caveat about breaking changes and no durability guarantees during the preview period. The code and API surface are open, with the reference implementation and schema published on GitHub and a hosted API for client integration."

MCP provides a standard protocol that allows IDEs and agents to connect uniformly to tools and data, described as 'like a USB-C port for AI applications.' An MCP Registry publishes a machine-readable catalog of MCP servers for clients to query and install, emphasizing federated discovery so public marketplaces and private sub-registries can mirror and extend against a shared OpenAPI. The preview includes moderation (including deny-listing) and warns of breaking changes and no durability guarantees during the preview. Agentgateway is an AI-native proxy proposed as a data plane to govern agent-to-agent, agent-to-tool, and agent-to-LLM interactions with support for protocols such as A2A and MCP.
