One MCP connector for your mobile app marketing stack

The stack, step by step

• Spend: Meta Ads, Google Ads and TikTok Ads — spend, impressions, clicks and conversions by campaign.
• Installs: AppsFlyer — installs and in-app events by media source and campaign; App Store Connect — Apple’s own downloads by country and the App Store funnel.
• Trials and revenue: RevenueCat — MRR, trials, conversion and churn; App Store Connect — sales, proceeds and subscription events.
• The store page: public App Store data — version, rating, reviews and top charts by country for any app, yours or a competitor’s, with no key.
• Around it: GA4, Search Console, Instagram and Facebook Pages.

Questions that cross sources

Marketing Kit reads each source as it reports; the assistant combines them. Ask for things like:

• “Cost per install last week: Meta and TikTok spend divided by AppsFlyer installs for the same media sources.”
• “Trial conversion this month from RevenueCat, next to new downloads from App Store Connect.”
• “Spend across Meta, Google Ads and TikTok against RevenueCat revenue, per day for the last 30 days.”
• “Do AppsFlyer and RevenueCat count the same purchases twice?”
• “How did our rating and latest reviews change after the last release?”

Honest about the numbers

Each platform counts its own way: ad platforms by their attribution, AppsFlyer by its attribution, RevenueCat by store transactions, Apple by Pacific-time days. Marketing Kit does not merge them into one model. A ratio built from two sources (spend from one, revenue from another) is blended across channels, not attributed to a campaign; ask the assistant to show each source’s number next to the result.

How to connect

1. Install Marketing Kit: in Claude, the plugin from claude.ai/customize/plugins; in ChatGPT, the connector in Developer mode.
2. On Connections authorize Meta, Google and TikTok in their own dialogs, and save the keys for AppsFlyer, RevenueCat and App Store Connect. Public App Store data needs nothing.
3. Ask in a new chat. A good first message: “check Marketing Kit status”.

Access and privacy

• Read-only, except the changes you confirm in chat (AppsFlyer OneLink links and turning on App Store Connect Analytics Reports).
• Tokens and keys are encrypted at rest (AES-256-GCM) and never shown back, logged or put into answers.
• Your numbers are fetched when you ask and not stored beyond a 15-minute in-memory cache; large results wait behind a download link for up to 24 hours. See the privacy policy.
• Disconnect a source, remove a key or delete your account on the site at any time.
