App Store Connect MCP Server

By Trial and Error Inc
The reliable bridge between App Store Connect and AI assistants

Problem

You need iOS app metrics in Claude. The "official" MCP servers are broken. Manual exports waste hours. This fixes that.

Solution

A working MCP server for App Store Connect. Built in 3 hours. No dependencies on broken packages. It just works.

Quick Start

# Clone the repo
git clone https://github.com/TrialAndErrorAI/appstore-connect-mcp
cd appstore-connect-mcp

# Install dependencies
npm install

# Build
npm run build

# Configure Claude Desktop
# Add to ~/Library/Application Support/Claude/claude_desktop_config.json:
{
  "mcpServers": {
    "appstore-connect": {
      "command": "node",
      "args": ["/path/to/appstore-connect-mcp/dist/index.js"],
      "env": {
        "APP_STORE_KEY_ID": "YOUR_KEY_ID",
        "APP_STORE_ISSUER_ID": "YOUR_ISSUER_ID",
        "APP_STORE_P8_PATH": "/path/to/key.p8"
      }
    }
  }
}

# Restart Claude Desktop

Getting App Store Connect Credentials

1. Go to App Store Connect
2. Navigate to Users and Access → Keys
3. Click "+" to generate a new key
4. Select "Admin" or "Finance" role
5. Download the .p8 file (ONLY downloadable once!)
6. Note your Key ID and Issuer ID

What You Can Ask Claude

Once configured, Claude can help you with:

• Financial Metrics: "What's our iOS monthly recurring revenue?"
• Subscription Analytics: "Show me active subscriber count and churn rate"
• App Performance: "List all our iOS apps with their current versions"
• Revenue Insights: "Calculate our ARR and growth rate"
• API Health: "Test the App Store Connect connection"
• Usage Monitoring: "Show API rate limit status"

More features coming soon: crash analytics, TestFlight metrics, customer reviews

Why We Built This

Our portfolio company RenovateAI is ranked #28 in Design Tools on the App Store. We needed real-time iOS metrics in Claude to make data-driven decisions. The existing solutions failed us:

• @joshuarileydev/app-store-connect-mcp-server - NPM 404 error
• Manual API integration - Days of work, maintenance burden
• CSV exports - Manual, error-prone, time-consuming

So we built our own. Clean, typed, reliable. In 3 hours flat.
