Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

923 endpoints. 2 tools. The spec IS the implementation.

[](https://www.typescriptlang.org/) [](https://modelcontextprotocol.io) [](https://opensource.org/licenses/MIT) [](https://developer.apple.com/app-store-connect/api/)

The Problem

Traditional MCP servers wrap each API endpoint as a separate tool. Apple's App Store Connect API has 923 endpoints. That means 923 tool definitions, ~100K+ context tokens, and a new release every time Apple adds an endpoint.

The Solution

Code Mode: 2 tools replace 923.

The LLM writes the query. The spec IS the implementation. Adding endpoints = Apple updates their spec. Zero code changes on our side.

Traditional MCP:  923 endpoints → 923 tools → ~100K tokens → constant maintenance
Code Mode:        923 endpoints → 2 tools   → ~1K tokens   → zero maintenance

Quick Start

1. Get App Store Connect credentials

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

2. Install via Claude Code

claude mcp add appstore-connect -s user \
-e APP_STORE_KEY_ID=YOUR_KEY_ID \
-e APP_STORE_ISSUER_ID=YOUR_ISSUER_ID \
-e APP_STORE_P8_PATH=/absolute/path/to/AuthKey_XXXXXXXXXX.p8 \
-e APP_STORE_VENDOR_NUMBER=YOUR_VENDOR_NUMBER \

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.
