One catalog for all your servers

The Horizon Registry provides a centralized catalog of all available MCP servers—internal and external—visible to authorized users. A single source of truth for what servers exist, who maintains them, and how to access them.

Horizon Registry

Discovery and cataloging

Organizations need to bless only certain MCP servers. They want to track both internal servers built by their teams and external third-party servers. Without a registry, teams download random server versions from unvetted sources, creating security exposure and version fragmentation.

Internal Servers

Catalog servers built by your teams. Track ownership, versions, and documentation in one place.

External Servers

Register approved third-party servers. Tell your teams: this is the GitHub server version you can use.

Single Source of Truth

No more scattered servers. Everyone knows what's available and where to find it.
