Introducing the Sunpeak Resource Repository

Source: Dev.to

Overview

Today we’re launching the Sunpeak Resource Repository—ECR for ChatGPT Apps.
ChatGPT Apps run on MCP servers, but UI resources can be stored separately, giving you several benefits.

Benefits

• Generic MCP servers – Keep your production MCP server generic and largely client‑agnostic.
• Independent lifecycles – Clearly indicate which code changes and version tags require ChatGPT App submission reviews and which are entirely MCP server‑side.
• Team collaboration – Designers and frontend developers can push UI changes without touching server infrastructure, and vice versa.
• Independent deployments – Update your UI without redeploying your server.

Authentication

sunpeak login

This opens your browser for secure OAuth authentication. Sunpeak stores local configuration in ~/.sunpeak/.

Building and Publishing Resources

# Build your resources
sunpeak build

# Push them to the repository
sunpeak push

Tagging for Versioning

sunpeak push -t v1.0.0 -t staging

Retrieving Resources

# Pull resources by tag from any directory
sunpeak pull -r myorg/my-app -t prod

This downloads the JavaScript bundles and metadata files, ready for deployment.

Rollback to a Previous Version

sunpeak pull -r myorg/my-app -t v1.0.0
sunpeak deploy   # Shorthand for `sunpeak push -t prod`

Promote Staging to Production

sunpeak pull -r myorg/my-app -t staging
sunpeak deploy
