Configuration
| Variable | Required | Secret | Description |
|---|---|---|---|
| ASC_KEY_ID | — | — | App Store Connect API Key ID. Normally written for you by `npx -y @erayendes/asc-mcp setup`. |
| ASC_ISSUER_ID | — | — | App Store Connect Issuer ID (a UUID). Normally written for you by `setup`. |
| ASC_PRIVATE_KEY | — | yes | The .p8 private key as PEM text. Prefer `setup`, which stores it in the macOS Keychain instead of any config file; set this only where a Keychain is unavailable, such as CI. |
