Free while in beta
Facts checked on 2026-10-04
In short
- Supermetrics MCP fits if you need many platforms: its data source list has 175 entries, from LinkedIn Ads to Shopify and HubSpot.
- Marketing Kit fits if your questions are about a mobile app: spend from Meta, Google Ads and TikTok, installs from AppsFlyer, subscriptions from RevenueCat, sales and analytics from App Store Connect.
Changing things
Supermetrics’ MCP documentation lists, in beta, a tool that creates or updates ad campaigns across Google, Meta, Microsoft, TikTok, LinkedIn, ChatGPT and Snapchat Ads. Marketing Kit has no tool that changes campaigns: it reads ad platforms, and its only changes — AppsFlyer OneLink links and partner integration copies, and turning on App Store Connect Analytics Reports — run after your explicit yes.
Your data on our side
- 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.

Questions
Is Marketing Kit free?
Free while in beta; pricing will be announced in advance. Fees apply only after you agree to them (Terms, section 7).
Does Supermetrics MCP support AppsFlyer and App Store data?
Their MCP data source list on 2026-10-04 had AppsFlyer, Apple Public Data and Apple Search Ads; RevenueCat and App Store Connect were not in it.
Is Marketing Kit read-only?
Every tool reads, except two that run only after your explicit yes: AppsFlyer OneLink links (with partner integration copies) and turning on App Store Connect Analytics Reports. Nothing changes ad campaigns.
Does it work in ChatGPT?
Yes. Add https://marketing-kit.app/mcp as a connector in ChatGPT Developer mode, on chatgpt.com with Plus, Pro, Business, Enterprise or Edu; in Business workspaces only admins and owners can turn Developer mode on. The steps are on Install.
Is my data stored?
No. Your marketing numbers are fetched when you ask and passed to your assistant. The server keeps a short in-memory cache (about 15 minutes, per user) so identical requests are not repeated, and a result too large for the chat waits behind a download link for up to 24 hours, for you only. Details are in the privacy policy.
