AppSigma's App Store MCP

MCP Server

App Store data,built for AI agents

Connect Claude, Cursor or any MCP client to AppSigma and let your AI research apps, read reviews and track rankings on its own — no glue code.

$ claude mcp add \ --transport http appsigma \ https://api.appsigma.io/mcp \ --header "X-API-Key: demo"

Paste it and ask away — the demo key works without an account on sample apps and charts. Swap in your own key for the full App Store.

Start free — 1,000 credits

No card required. A credit is one row of data — 1,000 credits is a lot of research.

From real Claude Code sessions using the AppSigma MCP server — one plain-English prompt in, App Store answers out.

> are habit tracker apps saturated?

One server, 21 tools

Every endpoint of our App Store API is exposed as an MCP tool your AI can call directly.

Apps & Metadata

Search the App Store, fetch full app details, version history, in-app purchases and similar apps.

Reviews & Ratings

Pull customer reviews across countries, rating histograms over time and ratings by version.

Charts & Prices

Current chart positions, chart history per app or genre, and full price change history.

Developers & Events

Browse a developer's whole portfolio, in-app events and App Store editorial features.

Ask things like “What do users complain about in my competitor's recent reviews?” or “How did this app's chart position change after its last price drop?” — your AI picks the tools and does the digging.

Connected in two minutes

1. Get your API key

The demo key works straight away on sample apps. For the full App Store, sign up free and generate your own key — it comes with 1,000 free credits, no card required.

2. Add the server to your client

Point Claude Code, Claude Desktop, Cursor or any MCP client at our endpoint with your key. That's the whole setup.

3. Just ask

A credit is one row of data — one review, one chart entry, one app record; searches cost 5. Tool calls bill exactly like the REST endpoints they wrap, on the same free tier.

See credit costs and plans on the pricing page, or the full API reference in the docs.
