Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Track your apps' keyword rankings, reviews and store listings on App Store, Google Play and more.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.
list_appsUse this when someone asks which apps they track in AppSkyline, or an app's id is needed. Returns each app's id, name, default locale and its App Store, Mac App Store, Google Play and Microsoft Store ids, up to 100 apps. Not for finding other apps in a store.
get_appUse this when someone asks about one of their AppSkyline apps, such as which stores it is on or which languages it supports. Returns the app's name, default and supported locales, App Store, Mac App Store, Google Play and Microsoft Store ids, and creation and edit times. Not for
list_keywordsUse this when someone asks which keywords they track for an app, or before adding or deleting one. Returns each tracked keyword's id, search term, language, country and bid, up to 500 per call. Not for current rankings or search volume.
search_store_resultsUse this when someone asks which apps show up for a search term, or who their competitors are for a keyword, on the App Store, Mac App Store, Google Play or Microsoft Store. Returns the live results in rank order with store id, title, rating and developer (10 by default, up to 20
get_keyword_rankUse this when someone asks where their app ranks for a keyword right now in one store and country. Returns the app's live position, or not-ranked, after scanning the top 50 results by default and up to 200, and renders a rank card. Not for how a rank changed over time.
get_keyword_historyUse this when someone asks how their app's ranking for a keyword has changed over time in one store and country. Returns the app's rank on each date AppSkyline stored a search snapshot, newest first, up to 365 rows; tracked keywords are re-checked weekly. Not for today's live ran
get_keyword_overviewUse this when someone asks how popular a keyword is or which keyword ideas are worth targeting. Returns monthly Google web-search volume (a demand proxy, not app-store search counts), difficulty, CPC and competition for up to 50 terms in one country. Terms missing from the 30-day
get_store_listingUse this when someone asks about a competitor's or any app's public store page, such as its rating, number of ratings, price, version or last update. Returns the live listing for one store id, with description and release notes cut to 600 characters. Not for your own app's synced
get_store_metadataUse this when someone asks about their own app's listing text per language, such as the title, subtitle, keywords or release notes, or whether the latest version is still in review or approved. Returns the metadata AppSkyline last synced for each locale, with the version, its rev
suggest_store_metadataUse this when someone asks which keywords to put in their app's title, subtitle, keyword field or short description, or how to improve their store listing's ASO. Without appId it covers every app in its main market, so one call answers 'for each app'. Compares each listing (synce
get_app_engagement_summaryUse this when someone asks how many downloads, installs, uninstalls or crashes their app had over a period. Returns store-reported totals, the latest 30 daily rows and top countries for one app and store; metric names differ by store. Not for keyword rankings.
list_google_play_reviewsUse this when someone asks what users say about their Android app on Google Play, or about recent ratings and complaints. Returns reviews with stars, text cut to 300 characters, app version, device, language and whether the developer replied, up to 100 per page. Google Play only
add_keywordUse this when someone asks to start tracking a keyword for their app in a given language and country. Returns the new keyword; adding the same term twice creates two rows. Keywords without a country are skipped by the weekly rank check. Not for a one-off rank lookup.
delete_keywordUse this when someone asks to stop tracking one of their keywords. Returns deleted, or not-found for an unknown id or one outside the account. Weekly rank checks stop and past snapshots stay, leaving a gap if it is tracked again later. Not for pausing tracking temporarily.
open_appskylineUse this when someone wants to open AppSkyline and browse their workspace interactively. Apps, connected stores and tracked keywords. Starts with up to 100 items. Not for changing data.
show_app_overviewUse this when someone wants a quick overview of one of the apps they track in AppSkyline. Returns an overview card with the app's connected stores, locales and up to 50 tracked keywords. Not for keyword rankings.

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
