appdex-mcp

MCP server for iOS App Store revenue & download estimates — ask any app's numbers straight from Claude Desktop, Cursor, or any MCP-capable agent.

Every figure ships with a confidence label (verified · calibrated · modeled) instead of a fake-precise single number, so an agent can tell the difference between a measured fact and an estimate.

Tiers

Upgrade at https://app-dex.com/pricing. The same key works for both tiers.

Configuration

APPINTEL_API_KEY / APPINTEL_API_URL are still read as fallbacks for older setups.

What the confidence labels mean

• verified — reported figure from a real data layer, not modeled.

• calibrated — modeled, but calibrated against verified panel data for that revenue class.

• modeled — limited public signal; treat as directional, read the range not the midpoint.

Notes & limits

• iOS App Store only. Figures are gross (before store commission) unless stated otherwise.

• Estimates are recomputed nightly.

• Single-app lookups by design — there is no bulk export endpoint.

• Rate limits are per key, per day (Europe/Istanbul day boundary). The tools report your remaining quota.
