What is an MCP Registry?¶
An MCP registry is a discovery catalog for MCP servers. It lets AI clients, IDE plugins, and other tooling find available MCP servers by name and version.
A registry stores metadata about each server: its name, version, description, capabilities, and the endpoint URL. Consumers query the registry to discover what servers are available and how to connect to them.
The API Platform MCP Registry¶
API Platform includes a built-in MCP registry scoped to each organization. When you publish an MCP proxy from the AI Workspace, it is registered in your organization's registry.
The MCP registry is surfaced in two ways:
- MCP Registry API: A REST API for discovery, intended for AI clients, IDE plugins, and automation tooling. It is built on the MCP Registry API specification.
- MCP Hub: A visual catalog for browsing and discovering MCP servers registered in your organization. The MCP Hub is powered by the MCP registry.
