asc RevenueCat catalog sync

Use this skill to keep App Store Connect (ASC) and RevenueCat aligned, including creating missing ASC items and mapping them to RevenueCat resources.

When to use

• You want to bootstrap RevenueCat from an existing ASC catalog.
• You want to create missing ASC subscriptions/IAPs, then map them into RevenueCat.
• You need a drift audit before release.
• You want deterministic product mapping based on identifiers.

Preconditions

• asc authentication is configured (asc auth login or ASC_* env vars).
• RevenueCat MCP server is configured and authenticated.
• In Cursor and VS Code, OAuth auth is available for RevenueCat MCP. API key auth is also supported.
• You know:
  • ASC app ID (APP_ID)
  • RevenueCat project_id
  • target RevenueCat app type (app_store or mac_app_store) and bundle ID for create flows
• Use a write-enabled RevenueCat API v2 key when applying changes.

Safety defaults

• Start in audit mode (read-only).
• Require explicit confirmation before writes.
• Never delete resources in this workflow.
• Continue on per-item failures and report all failures at the end.

Canonical identifiers

• Primary cross-system key: ASC productId == RevenueCat store_identifier.
• Keep productId stable once products are live.
• Do not use display names as unique identifiers.

Scope boundary

• RevenueCat MCP configures RevenueCat resources; it does not create App Store Connect products directly.
• Use asc commands to create missing ASC subscription groups, subscriptions, and IAPs before RevenueCat mapping.

Modes

1) Audit mode (default)

1. Read ASC source catalog.
2. Read RevenueCat target catalog.
3. Build a diff with actions:
   • missing in ASC
   • missing in RevenueCat
   • mapping conflicts (identifier/type/app mismatch)
4. Present a plan and wait for confirmation.

2) Apply mode (explicit)

Execute approved actions in this order:

1. Ensure ASC groups/subscriptions/IAP exist.
2. Ensure RevenueCat app/products exist.
3. Ensure entitlements and product attachments.
4. Ensure offerings/packages and package attachments.
5. Verify and print a final reconciliation summary.

Step-by-step workflow

Step A - Read current ASC catalog

asc subscriptions groups list --app "APP_ID" --paginate --output json
asc iap list --app "APP_ID" --paginate --output json
# for each subscription group:
asc subscriptions list --group-id "GROUP_ID" --paginate --output json

Step B - Read current RevenueCat catalog (MCP)

Use these MCP tools (with project_id and pagination where applicable):

• mcp_RC_get_project
• mcp_RC_list_apps
• mcp_RC_list_products
• mcp_RC_list_entitlements
• mcp_RC_list_offerings
• mcp_RC_list_packages

Step C - Build mapping plan

Map ASC product types to RevenueCat product types:

• ASC subscription -> RevenueCat subscription
• ASC IAP CONSUMABLE -> RevenueCat consumable
• ASC IAP NON_CONSUMABLE -> RevenueCat non_consumable
• ASC IAP NON_RENEWING_SUBSCRIPTION -> RevenueCat non_renewing_subscription

Suggested entitlement policy:

• subscriptions: one entitlement per subscription group (or explicit map provided by user)
• non-consumable IAP: one entitlement per product
• consumable IAP: no entitlement by default unless user asks

Step D - Ensure missing ASC items (if requested)

Create or complete ASC resources first, then re-read ASC to capture canonical IDs. A RevenueCat product mapping is not proof that the corresponding ASC subscription is review-ready.

# create subscription group
asc subscriptions groups create --app "APP_ID" --reference-name "Premium"

# create or converge a review-ready subscription in one workflow
asc subscriptions setup \
  --app "APP_ID" \
  --group-reference-name "Premium" \
  --group-locale "en-US" \
  --group-display-name "Premium" \
  --reference-name "Monthly" \
  --product-id "com.example.premium.monthly" \
  --subscription-period ONE_MONTH \
  --locale "en-US" \
  --display-name "Premium Monthly" \
  --description "Unlock all premium features." \
  --review-screenshot "./review.png" \
  --price "3.99" \
  --price-territory "USA" \
  --territories "USA"

# create iap
asc iap create \
  --app "APP_ID" \
  --type NON_CONSUMABLE \
  --ref-name "Lifetime" \
  --product-id "com.example.lifetime"

subscriptions setup must finish the ASC metadata that RevenueCat cannot: group localization, subscription localization, App Review screenshot delivery, the complete App Store price matrix, and sale availability. Keep sale availability scoped to the requested territories; pricing still needs Apple's complete equalized territory matrix.

If an existing API-created subscription remains MISSING_METADATA even though the selected base price is unchanged, re-run the same setup inputs with --repair. Repair atomically rebuilds and re-saves the complete equalized price matrix; it is not a duplicate single-price POST.

After every ASC subscription create, update, or repair, require this final gate before creating or attaching the RevenueCat subscription product:

mkdir -p "./audit"
asc validate subscriptions --app "APP_ID" --output json --pretty \
  > "./audit/subscriptions-validation.json"

After every ASC IAP create or update, require the IAP gate in strict mode so warnings also block the RevenueCat product mapping:

mkdir -p "./audit"
asc validate iap --app "APP_ID" --strict --output json --pretty \
  > "./audit/iap-validation.json"

Do not treat setup as successful if Apple still reports MISSING_METADATA, the review screenshot is not COMPLETE, or the validator reports incomplete or unverified pricing coverage. Do not attach an IAP while its strict validator reports warnings or errors. Direct redirection preserves each validator's exit status. Retain ./audit/subscriptions-validation.json and ./audit/iap-validation.json as final audit evidence.

Step E - Ensure RevenueCat app and products

Use MCP:

• create app if missing: mcp_RC_create_app
• create products: mcp_RC_create_product
  • store_identifier = ASC productId
  • app_id = RevenueCat app ID
  • type from mapping above

Step F - Ensure entitlements and attachments

Use MCP:

• list/create entitlements: mcp_RC_list_entitlements, mcp_RC_create_entitlement
• attach products: mcp_RC_attach_products_to_entitlement
• verify attachments: mcp_RC_get_products_from_entitlement

Step G - Ensure offerings and packages (optional)

Use MCP:

• list/create/update offerings:
  • mcp_RC_list_offerings
  • mcp_RC_create_offering
  • mcp_RC_update_offering (is_current=true only if requested)
• list/create packages:
  • mcp_RC_list_packages
  • mcp_RC_create_package
• attach products to packages:
  • mcp_RC_attach_products_to_package with eligibility_criteria: "all"

Recommended package keys:

• ONE_WEEK -> $rc_weekly
• ONE_MONTH -> $rc_monthly
• TWO_MONTHS -> $rc_two_month
• THREE_MONTHS -> $rc_three_month
• SIX_MONTHS -> $rc_six_month
• ONE_YEAR -> $rc_annual
• lifetime IAP -> $rc_lifetime
• custom -> $rc_custom_<name>

Expected output format

Return a final summary with:

• ASC created counts (groups/subscriptions/IAP)
• RevenueCat created counts (apps/products/entitlements/offerings/packages)
• attachment counts (entitlement-products, package-products)
• skipped existing items
• failed items with actionable errors

Example:

ASC: created groups=1 subscriptions=2 iap=1, skipped=14, failed=0
RC: created apps=0 products=3 entitlements=2 offerings=1 packages=2, skipped=27, failed=1
Attachments: entitlement_products=3 package_products=2
Failures:
- com.example.premium.annual: duplicate store_identifier exists on another RC app

Agent behavior

• Always run audit first, even in apply mode.
• Ask for confirmation before create/update operations.
• Match by store_identifier first.
• Use full pagination (--paginate for ASC, starting_after for RevenueCat tools).
• Continue processing after per-item failures and report all failures together.
• Never auto-delete ASC or RevenueCat resources in this skill.
• After ASC subscription writes, run asc validate subscriptions --app "APP_ID" --output json --pretty, save its JSON, and block RevenueCat attachment for subscriptions with unresolved ASC blockers.
• After ASC IAP writes, run asc validate iap --app "APP_ID" --strict --output json --pretty, save its JSON, and block RevenueCat attachment if it exits non-zero.

Common pitfalls

• Wrong RevenueCat project_id or app ID.
• Creating RC products under the wrong platform app.
• Accidentally assigning consumables to entitlements.
• Skipping the post-create ASC re-read step.
• Mapping a RevenueCat product before ASC setup finishes localization, review screenshot delivery, the complete price matrix, and availability.
• Missing offering/package verification after product creation.
