> Fledly, AppFollow, Appfigures, AppTweak, Sensor Tower, MobileAction, Appbot, ASO.dev, Sonar, Astro and open-source servers compared: what App Store data each gives Claude or ChatGPT, remote or local, sign-in, plans and price. Checked November 10, 2026.

**Key takeaways**

- **Free to connect:** Fledly, AppFollow and Appfigures include their remote MCP server on the free plan, and Sonar has a limited free mode.
- **Local servers:** Astro's comes with its $108-a-year Mac app and ASO.dev's with its desktop app.
- **Your own sales and downloads:** Appfigures. **Reviews:** AppFollow or Appbot. **Keyword research and ranks on both stores:** Sonar. **Market estimates for any app:** Sensor Tower, AppTweak's API or MobileAction, on API plans.
- **Fledly** is a remote server at fledly.app/mcp with OAuth sign-in and 18 tools, on every plan including Free. Its own data is young iPhone apps already on the Top Grossing charts, with revenue estimate ranges, and scored app ideas. It is iOS only.

There are now more than ten MCP servers that give an AI assistant App Store data, and they answer different questions: Appfigures gives your own sales, AppFollow and Appbot give reviews, Sonar and Astro give keyword ranks, and Sensor Tower, AppTweak and MobileAction give market estimates on API plans. Fledly, AppFollow and Appfigures can be connected on a free plan with OAuth sign-in, while Astro and ASO.dev run locally inside their desktop apps.

*Disclosure: we make Fledly. Every fact about another server comes from that vendor's own site, docs, help center, pricing page or GitHub repository, or for open-source servers the project's own repository, checked on November 10, 2026; "not published" means we couldn't find it there. AppFollow's roundup of App Store MCP servers was used only to find vendors, not as a source for their facts. Prices exclude VAT. AppFollow and AppTweak showed euro prices to our European connection; US dollar prices may differ.

1. Our count of the tools in AppFollow's own toolkit tool map, including 7 preview-and-confirm helpers. AppFollow doesn't state a number.
2. Counted from the tool table in AppTweak's API MCP docs. AppTweak's second server, for ASO subscribers, doesn't publish a tool count.
3. Appbot's feature and plans pages say Large and Premium; its Claude help article lists all four plans.

## What each server is good at

### Fledly

[Fledly's MCP server](/docs/mcp/) is a remote server at `https://fledly.app/mcp` with OAuth 2.1 sign-in, so you add the URL in Claude, ChatGPT, Cursor or Claude Code and sign in once. It has 18 tools and is included in every plan: Free shows the top results of idea and young-earner lists and tracks 1 app with 15 searches; Pro is $9 a month or $79 a year; Studio is $24 a month or $199 a year.

The data Fledly adds is market evidence for deciding what to build: young iPhone apps that already appear on the Top Grossing charts in six App Stores, with revenue estimate ranges, and app ideas scored from them. It also looks up any app, suggests keywords, tracks your ranks and competitors, and checks metadata against Apple's limits. Fledly is iOS only: no Google Play, no review replies, no access to your own App Store Connect sales, and no REST API, only MCP and the web app.

### AppFollow

AppFollow's remote server signs in with Google or SSO, and its Free plan lists the MCP connector. Its tools cover reviews (reading, replying, tags, AI summaries), ratings, ranks, tracked keywords and ASO reports across the App Store, Google Play and other stores. If reviews and replies are your main job, it does far more there than Fledly.

### Appfigures

Appfigures' remote server needs no API key, and anyone with an Appfigures account can connect. The assistant sees what your plan includes: your own downloads, revenue, subscriptions and reviews from App Store Connect and Google Play, plus ranks and keywords. Download and revenue estimates for other apps need the Boost plan ($599.99 a month, or $449.99 billed yearly) and a Public Data add-on whose price isn't published. It's the server built for asking about your own business in chat.

### Sonar

Sonar includes its MCP server, CLI and REST API on every plan, from Indie at $29 a month. It states 80 tools, covers the App Store and Google Play, and offers a free mode with 7 tools, limited to 5 keywords' metrics a day. It's built for keyword research and rank tracking from an agent across both stores, at an indie price.

### AppTweak

AppTweak has two servers. The API server at `app.apptweak.com/api/mcp` exposes the whole AppTweak API through 10 tools and needs an API plan, from Lite at €199 a month (€166 billed yearly), with requests paid in credits. A second server at `app.apptweak.com/mcp` serves AppTweak subscribers; which plans include it isn't published.

### Sensor Tower and MobileAction

Both are for companies that already have an API contract. Sensor Tower's server needs an active Sensor Tower API subscription and gives its download, revenue, ad spend and retention estimates; the price is on request. MobileAction's remote server exposes its API (ranks, charts, estimates, reviews and Apple Ads data) with a token from your account manager in the URL, on a custom-priced API Solutions plan.

### Appbot

Appbot's server is read-only and does one thing: review sentiment, topics and ratings for your apps and tracked competitors, through 3 tools. Its pages list it on the Large plan (from $166 a month billed yearly) and above.

### ASO.dev and Astro

Both run on your computer. ASO.dev's server lives in its desktop app at `localhost:42111` and edits your own listings in App Store Connect and Google Play; its docs say it does not expose ASO.dev's keyword data. Astro's beta server runs inside the Mac app at `127.0.0.1:8089` and lets a local agent read your tracked keywords and ranks; Astro's docs list 12 tools. Cloud assistants such as Claude on the web need a tunnel to reach either.

### Open-source servers

Projects such as appreply-co/mcp-appstore (17 tools) and JiantaoFu/AppInsightMCP (20 tools) wrap public App Store and Google Play scraper libraries. They're free and need no account, but you run them yourself, they have no history, and scraped endpoints can break or rate-limit without notice.

## Which one to connect

- **"How is my app doing?"** Appfigures, for your own downloads, revenue and reviews.
- **"Answer and analyse my reviews."** AppFollow, or Appbot for read-only sentiment.
- **"Which keywords should I target, on iOS and Android?"** Sonar.
- **"How big is this market, for any app?"** Sensor Tower, AppTweak's API or MobileAction, if you have an API budget.
- **"Edit my listing from Claude."** ASO.dev.
- **"What should I build next, and is anyone new already earning there?"** Fledly: ask for young earners or proven app ideas, then track your keywords once you ship. [Connect Fledly](/docs/mcp/).

Several of these work together: an assistant can use Fledly for idea research and Appfigures for your own numbers in the same chat.

## Frequently asked questions

### What is an App Store MCP server?

A server that speaks the Model Context Protocol, so an AI assistant such as Claude, ChatGPT or Cursor can call it as a tool to read App Store data, for example rankings, reviews, keyword data or revenue estimates, while you chat. Remote servers are added by URL and sign in with OAuth; local ones run on your computer.

### Is there a free App Store MCP server?

Yes. Fledly, AppFollow and Appfigures include their remote MCP servers on free plans, each limited to what that plan includes. Sonar has a free mode with 7 tools and 5 keywords' metrics a day. Open-source servers are free but you run them yourself.

### Which App Store MCP servers also cover Google Play?

AppFollow, Appfigures, Sonar, AppTweak, MobileAction, Appbot and ASO.dev cover both stores. Fledly and Astro cover the App Store only.

### Can Claude read my App Store Connect sales through MCP?

Yes, through Appfigures, which reads your connected App Store Connect and Google Play accounts. ASO.dev reads and edits your listings rather than sales. Fledly doesn't connect to App Store Connect.

### Does Fledly have an API?

Fledly is available through its MCP server (18 tools) and the web app. It has no REST API.
