App Store & Google Play ranking data as an MCP server. Ask your assistant which keywords you dropped on, who outranks you, and whether AI assistants mention your app at all — without opening a dashboard.

Backed by Storelift, which measures keyword ranks, rivals and AI visibility nightly. No store credentials required — ranks are read from the public storefront.

Requirements

A Pro or Studio plan (the Public API is enabled on both)
An API key: Storelift → Settings → API keys → Generate key

Install

Claude Code:

claude mcp add storelift -e STORELIFT_API_KEY=sl_live_... -- npx -y storelift-mcp

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "storelift": {
      "command": "npx",
      "args": ["-y", "storelift-mcp"],
      "env": { "STORELIFT_API_KEY": "sl_live_..." }
    }
  }
}

Hosted, with nothing to install — https://storelift.net/mcp over Streamable HTTP. Clients that support MCP authorization (Claude.ai custom connectors, Claude Code's /mcp) sign you in to Storelift with OAuth and ask you to approve access; no key to paste:

claude mcp add --transport http storelift https://storelift.net/mcp

Clients without OAuth can send the API key as a header instead:

claude mcp add --transport http storelift https://storelift.net/mcp --header "Authorization: Bearer sl_live_..."

Tools

Tool	Returns
`list_apps`	tracked apps (id, name, countries, keywords)
`get_keywords`	keyword ranks for one app in one country
`get_rivals`	apps ranking above you, with their rank and yours
`get_ai_visibility`	whether assistants name your app, per engine (Claude / ChatGPT / Gemini)
`get_history`	rank history, `[day, rank]` points
`get_store_page`	your own listing signals + the Google Play page, with a dated change timeline
`get_reviews`	recent App Store and Google Play reviews, and how many are new since last measurement
`get_charts`	App Store chart position per list, with history

Prompts

Five ready-made questions, served through prompts/list:

keywords_lost_ground — which US keywords lost ground this week, and who is above you now
leader_listing — title, subtitle and keyword field of the app ranking first on your main keyword
crash_reviews — recent reviews that mention a crash or a bug
category_chart — where your app sits in its category chart in Turkey
ai_visibility — whether assistants name your app for its category (data on the Studio plan)

Reading the data

Keyword results carry three distinct states, and they are not the same thing:

measured: false — the query could not be measured
rank: null (with measured: true) — measured, but absent from the top results
rank: <number> — the rank

Counting an unmeasured day as zero produces a false chart. The tool descriptions repeat this so the model does not flatten the three into one.

A rank move usually has its explanation somewhere other than the rank: a version that shipped that day, a wave of one-star reviews, a chart drop. get_store_page, get_reviews and get_charts exist so the model can look there instead of explaining everything with the one number it can see.

Google Play is absent from get_charts on purpose: Google publishes no chart list, so there is nothing to read and a number here would be invented.

AI visibility is an observation, not a ranking: a model's knowledge is frozen at a date and the answer is not identical every time. Read the trend, not a single measurement.

Configuration

Variable	Default	Purpose
`STORELIFT_API_KEY`	—	required for tool calls; without it the server still starts and lists its tools, and every call returns an error saying how to get a key
`STORELIFT_API`	`https://storelift.net`	override the API base

No dependencies — a single file speaking JSON-RPC over stdio. Runs with node index.mjs just as well as through npx.
