Environment / auth

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
secret
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.
ASC_PRIVATE_KEY_PATH
Path to the .p8 file, as an alternative to pasting its contents. Off macOS this is what `setup` records.
ASC_BUNDLE_ID
Bundle ID of one app. Only needed by the StoreKit 2 transaction tools on the monetization profile.
