app store mcp · ai agent

Connect your AI agent to your App Store data.

Add AppSigma's App Store MCP server to Claude, ChatGPT, Claude Code or Cursor in two minutes. Your agent then reads your keywords, positions, competitors and reviews, and tells you what to change to climb.

vibe-coded your app?

Then you already build with an AI agent. Give it your App Store data too: it finds the keywords you can win and rewrites your name and subtitle for them, right next to your code.

Just exploring? Try it without an account:

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

$ 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. For the full App Store, drop the --header and your client will ask you to sign in to AppSigma.

step 1

Connect

Add both servers: the first works with your apps, the second with any app in the store, which is how the agent reads your competitors' reviews.

In claude.ai or Claude Desktop open Settings → Connectors → Add custom connector, paste a URL, then press Connect and approve. Repeat for the second URL.

Your apps

Your tracked apps, keywords, positions, competitors, store activity and review insights. The agent can also track apps and add keywords. No credits: your plan limits apply.

https://appsigma.io/mcp

The whole App Store

Reviews, charts, metadata and prices of any app, including competitors you do not track. Billed in credits, the first 1,000 are free.

https://api.appsigma.io/mcp

In ChatGPT add a custom connector (Settings → Apps & Connectors, developer mode on), paste a URL and choose OAuth. ChatGPT opens AppSigma for you to approve.

Your apps

Your tracked apps, keywords, positions, competitors, store activity and review insights. The agent can also track apps and add keywords. No credits: your plan limits apply.

Run both commands, then /mcp in Claude Code and pick a server to sign in.

claude mcp add --transport http appsigma https://api.appsigma.io/mcp

Paste this into your client's MCP config (Cursor: Settings → MCP → Add new server). The client asks you to sign in on first use.

        "appsigma-account": {
            "type": "http",

When you approve the connection, your client opens AppSigma and you can sign up right there with your email. Or create the account first and come back to this page signed in.

step 2

Ask

Start with one of these. Your agent picks the tools and does the digging.

Pick better keywords

“Which keywords am I closest to the top 10 for, and which should I add?”

Follow the moves

“What moved this week?”

Measure the gap

“How far behind my competitors am I?”

Find competitors' weak spots

“What do the 1-star reviews of my competitor complain about?”

two.servers

Your apps, and the whole App Store.

One sign-in, two MCP servers. Add both and your agent picks the right one for each question.

appsigma.io/mcp

Your apps

Track apps, add and remove keywords, see position changes, manage competitors, read store activity and review insights. No credits: your plan limits apply, the same as in the app, and the free plan works too. You approve one organization for each connection.

> Which of my keywords are closest to the top 10, and which new ones should I track?
