2026 Launch Week | Day 3 | Deploy & Registry

Day 3: Horizon Deploy gets servers live in 60 seconds. Horizon Registry keeps you from rebuilding the same one 6 times. Radhika Gulati, Senior Product Marketing Manager breaks down Horizon Deploy and Registry. Deploy is CI/CD for MCP servers. You connect a GitHub repo, and one click gives you a production URL with OAuth. Push to main → automatic redeploy Create a branch → preview URL for testing Branch previews are critical because agents are non-deterministic. You need to test against live URLs and run evaluations before you ever merge to production. When deployment only takes one click, things scale fast. A 500-person company can easily end up with 30 internal servers for custom business logic and another 20 external integrations for Salesforce or HubSpot. Discovery became the new problem. Who built what? Which external servers are being imported? What tools does each one actually provide? Registry is the catalog. It provides a central view of every internal server your team has built and every external server they've imported. horizon.prefect.io
