Use when there is no public API for app creation and you need an agent to drive the New App form. Create a new App Store Connect app record via browser automation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# asc app create (UI automation)
Use this skill to create a new App Store Connect app by driving the web UI.
This is opt-in, local-only automation that requires the user to be signed in.
## Preconditions
- A browser automation tool is available (Playwright, Cursor browser MCP, or equivalent).
- User is signed in to App Store Connect (or can complete login + 2FA).
- The **bundle ID must already be registered** in the Apple Developer portal.
- Required inputs are known:
- app name (max 30 characters)
- bundle ID (must exist and be unused by another app)
- SKU
- platform (iOS, macOS, tvOS, visionOS)
- primary language
- user access (Full Access or Limited Access)
## Safety Guardrails
- Never export or store cookies.
- Use a visible browser session only.
- Pause for a final confirmation before clicking "Create" (for standalone scripts).
- Do not retry the Create action automatically on failure.
## Workflow
### 1. Preflight: register bundle ID and verify no existing app
```bash
# Register the bundle ID via public API (if not already registered)
asc bundle-ids create --identifier "com.example.app" --name "My App" --platform IOS
# Confirm no app record exists yet

The line at the top of this page pins the label git:20261028.88809da, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
