MCP doesn't get adopted
as a single server.
It gets adopted as a long tail. Registry is where that sprawl becomes manageable.
A GitHub server here.
A ticketing server there.
Then ten more.
Then someone forks one. Then nobody remembers which version is safe.
Registry is the answer to “Where is the GitHub server?” and “Which customer data tool is approved for production?”
The Catalog
Your central catalog of MCP capabilities
First-party · Third-party · Curated endpoints
Find MCP servers by name, capability, or connected system. See what's already built before starting new work.
Clear ownership for every server. Know who to ask when you need access or have questions.
Browse the tools and capabilities each server provides. Understand what's available before connecting.
Track approved versions for production use. Stop wondering if the server you found is the right one.
Remix Servers
Curation becomes concrete
The context era isn't just about collecting tools. It's about shaping decision spaces.
Horizon lets you build remix servers: virtual servers composed from any combination of first-party and third-party capabilities. Pull the exact tools you need from multiple sources and expose them as a single governed endpoint built for a specific workflow.
This minimizes both context pollution and the risk of misusing powerful tools. Remix servers can also be permissioned more strictly than their underlying sources.
That's a critical distinction. The permission model that makes a human effective can make an agent reckless.
