Connect AppTail once, then ask in plain language: how contested is a niche, which keywords dropped and who took the places, what one-star reviewers say, where your downloads come from. Every answer comes from real App Store data, with measured and estimated figures kept apart.
Listed in the official Claude connector directory. Install it from there, no URL to paste.

What you can ask
App store optimization, keyword research, competitor analysis and market research usually mean six tabs. Here they are questions to your assistant, and each one is a call or two against the same data.
“How contested is AI calorie tracking in the US, and is it softer in Germany?”
Leaders, saturation and search visibility per storefront, read separately and never blended into one invented score.

get_top_charts
“Which of my keywords dropped last month, and which apps took the places?”
Popularity, ranked apps and suggestions for any phrase and country. Tracked terms with day-by-day history.

“Who is beating me in search right now, and what did they take from me?”
Who shares your search niche, which terms they own, what they charge in each storefront, how their ratings move.

25 tools
One tool per question shape, not one per screen. Reading is most of it. The few that change something say so, and your assistant has to be allowed to write.
get_account
Your apps, plan and limits, App Store Connect health per app, and your focus storefronts. The call an assistant makes first.
explain_period
"What happened last month?" in one call: the period against the one before, storefronts that moved, keyword changes, findings and review volume.
get_signals
Rank moves, chart entries, review spikes, competitor releases and price changes, each with the numbers behind it.
get_performance
Needs App Store Connect
Apple's measured impressions, page views, downloads, sales and proceeds, for one app or the whole portfolio, by storefront or source.
get_keywords
Tracked terms over any window: rank at the start and end, movement, daily history, and the same terms for named competitors.
get_keyword_serp
Who ranked for a term in a storefront on a day you name, with names, subtitles and ratings. Works for terms you do not track.
discover_keywords
Terms you could be tracking and are not, each labelled with its source: rivals, similar apps, store mining, your own listing.
add_keywords
Writes
Start tracking terms for an app in one storefront. Batches report an outcome per term.
remove_keywords
Writes
Stop tracking terms. Rank history is kept, so re-adding one does not start from zero.
tag_keywords
Writes
Sort a large keyword list into groups such as brand, generic and competitor, in one call instead of an afternoon.
get_landscape
Who shares your search niche: every app, how many of your terms it ranks for, ratings, and the vocabulary you are missing.
get_competitors
The rivals you track against an app, suggested rivals you do not, and how many more your plan allows.
add_competitors
Writes
Track rivals by name, App Store URL or id. "Add the three closest" is one call.
remove_competitors
Writes
Stop tracking a rival against one of your apps.
get_market
Niche research for any phrase and storefronts: leaders, saturation, search visibility, vocabulary. Needs no app of your own.
list_markets
The markets you have saved, with competition ranges and what changed.
save_market
Writes
Save a niche to watch, with seed terms per storefront.
edit_market_corpus
Writes
Pin a term the market should hold, or exclude one that does not belong.
remove_market
Writes
Delete a saved market, or just one storefront of it.
search_apps
Find any App Store app by name in any language, bundle id or URL.
get_app
One app at the depth you ask for: listing, ratings by storefront, prices, charts, publisher portfolio, release history, screenshots.
get_top_charts
Top free, paid and grossing charts by storefront and category.
add_app
Writes
Add an app as one of yours. Rankings, reviews and competitors start filling in.
get_reviews
Reviews over any window, filtered by storefront, stars, text or unanswered, with volume and rating trends beside them.
reply_to_reviews
Writes
Needs App Store Connect key
Create, update or remove public review replies through your App Store Connect key. Dry run first, and drafts need your approval.
“Writes” means it changes your account. Research tools such as search_apps and get_market can import a public store record or cache a suggestion on our side so the next answer is faster, but they never add anything to your account. Clients such as ChatGPT ask you to confirm before a write runs.
Connect
The client sends you to an AppTail sign-in page, you approve it, and the connection belongs to your account. There is no key to generate, paste or leak.
Create a free account and add an app, or just research any app in the store.
In Claude, install it from the official directory. Elsewhere it is a URL pasted into a settings screen, or one command in a terminal. Pick your client on the right.
Start with “What happened to my apps last month?” or research any niche. No app of your own is needed for market and keyword research.
Easiest way
Install AppTail from the official Claude connector directory. No URL to paste.
Or add it manually

Saved workflows
Each one is a sequence over the tools above, written out so the answer comes back in the same shape every time. Your client lists them as prompts.
/monthly_review
A full month in review for one app or the whole portfolio: the money, the movers, the findings, and what is worth doing next.
/weekly_standup
The week in five lines: what moved, what needs answering, and nothing I have already been emailed.
/keyword_triage
Go through one app's tracked terms: what dropped and why, what is worth adding, and tag the corpus into brand, generic and competitor.
/competitor_brief
What a rival has been doing: where they rank against you, what shipped, what their users are saying, and where they are beating you.
/answer_reviews
Read one app's unanswered reviews, draft a reply to each in the reviewer's own language, and — after you have approved them — publish them to the App Store.
Straight talk
FAQ
An MCP (Model Context Protocol) server at https://mcp.apptail.io/mcp that lets Claude, ChatGPT, Codex, Cursor and other MCP clients read AppTail's iOS App Store data and your connected apps' analytics, and answer ASO, keyword research, competitor analysis and market research questions in plain language.
Any client that supports remote MCP servers with OAuth: Claude (web, desktop and Claude Code), ChatGPT on plans that allow custom MCP servers, Codex and Cursor. The setup steps for each are in the Connect section.
Yes. You sign in with your AppTail account when the client connects, and there is no API key to copy. Data access and tracking limits depend on your plan, and get_account reports them to the assistant.
Only through tools marked as writes, and only if writes are allowed for your account: you can switch them off on the Access page in your console. With writes on it can track keywords and competitors, tag keywords, save and edit markets, add apps, and, with an App Store Connect key connected, reply to reviews. Public review replies are drafted first and need your approval.
For apps you connect through App Store Connect, yes: impressions, page views, downloads, sales and proceeds are Apple's own measured figures. For anybody else's app, downloads and revenue are rolling 30-day third-party estimates, and every tool that returns them labels them as estimates.
No. The MCP server covers the iOS App Store only.
No. It returns Apple's search popularity index, the apps that rank, and how the results are composed, and the assistant describes how competitive that looks in words. A made-up difficulty number would not be evidence.
No. It can research, draft copy and recommend changes. Listing metadata is changed by you in App Store Connect. The one public write it can make is a review reply, with your approval.
No. There is no query surface. The assistant calls a fixed set of tools that return defined shapes, with coverage, freshness and caveats attached.
No credit card. No commitment.
