One server, 21 tools

Every endpoint of our App Store API is exposed as an MCP tool your AI can call directly.

Apps & Metadata

Search the App Store, fetch full app details, version history, in-app purchases and similar apps.

Reviews & Ratings

Pull customer reviews across countries, rating histograms over time and ratings by version.

Charts & Prices

Current chart positions, chart history per app or genre, and full price change history.

Developers & Events

Browse a developer's whole portfolio, in-app events and App Store editorial features.

Ask things like “What do users complain about in my competitor's recent reviews?” or “How did this app's chart position change after its last price drop?” — your AI picks the tools and does the digging.
