appdex-mcp
MCP server for iOS App Store revenue & download estimates — ask any app's numbers straight fromClaude Desktop, Cursor, or any MCP-capable agent.
Every figure ships with a confidence label (verified · calibrated · modeled) instead of afake-precise single number, so an agent can tell the difference between a measured fact and an estimate.

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.
