# App Store Connect MCP Server

**Automate App Store Connect from your AI agent.**

## Overview

This MCP server lets AI agents like Claude Code, Claude Desktop, and Cursor manage your App Store Connect workflows through natural language. Create versions, update metadata, attach builds, and submit for review — all without leaving your editor.

Built in Swift with the [MCP Swift SDK](https://github.com/modelcontextprotocol/swift-sdk), it connects directly to the [App Store Connect REST API](https://developer.apple.com/documentation/appstoreconnectapi) using ES256 JWT authentication.

## Key Features

- **Release workflows** — Prepare releases, check status, validate before submission, and clone metadata between versions
- **Version management** — Create, update, and list App Store versions
- **Localized metadata** — Add descriptions, keywords, release notes, and URLs for any locale
- **Build management** — List builds, upload IPAs, and attach builds to versions
- **Diagnostics & performance** — View diagnostic signatures, logs, and performance metrics per build
- **Review and publication** — Submit versions to App Review and manually release approved versions
- **Multi-organization** — Manage multiple App Store Connect teams from a single server
- **Secure auth** — ES256 JWT signing via Apple CryptoKit with automatic token refresh

## Build From Source (Setup)

Use this path if you want to work on or build this repository locally.

### Prerequisites

- macOS 13+, Swift 6.0+ / Xcode 16+
- [Tuist 4.x](https://docs.tuist.io/guides/quick-start/install-tuist) (`brew install tuist`)
- An [App Store Connect API key](https://developer.apple.com/documentation/appstoreconnectapi/creating_api_keys_for_app_store_connect_api) with **App Manager** role or higher

### Install and Build

```bash
./bootstrap.sh
```

This fetches dependencies, generates the Xcode project, and builds. Or manually:

```bash
tuist install && tuist generate && tuist build
```

### Configure

Choose the configuration that matches your App Store Connect API key.

#### Team API Key

Team keys require the issuer ID. `ASC_AUTH_MODE` defaults to `team`, but setting it
explicitly makes the configuration clear:

```bash
export ASC_KEY_ID="your-key-id"
export ASC_PRIVATE_KEY_PATH="/path/to/AuthKey_XXXXXX.p8"
export ASC_ISSUER_ID="your-issuer-id"
export ASC_AUTH_MODE="team"
```

#### Individual API Key

Individual keys do not use an issuer ID. Set `ASC_AUTH_MODE` to `individual` and
omit `ASC_ISSUER_ID`:

```bash
export ASC_KEY_ID="your-key-id"
export ASC_PRIVATE_KEY_PATH="/path/to/AuthKey_XXXXXX.p8"
export ASC_AUTH_MODE="individual"
```

Get these values from [App Store Connect > Users and Access > Integrations > App Store Connect API](https://appstoreconnect.apple.com/access/integrations/api).

## Install via npm

Use this path if you only want to run the MCP server and not build from source.

### Prerequisites

- Node.js 18+ and npm
- macOS

### Install/Run Command

```bash
npx -y @vvlladd/appstoreconnect-mcp
```

### Connect to Claude Code

Add one of the following configurations to `~/.claude.json` (global) or
`.claude/settings.json` (project) and use the npm package.

For a team API key:

```json
{
  "mcpServers": {
    "appstoreconnect": {
      "command": "npx",
      "args": ["-y", "@vvlladd/appstoreconnect-mcp"],
      "env": {
        "ASC_KEY_ID": "your-key-id",
        "ASC_PRIVATE_KEY_PATH": "/path/to/AuthKey.p8",
        "ASC_ISSUER_ID": "your-issuer-id",
        "ASC_AUTH_MODE": "team"
      }
    }
  }
}
```

For an individual API key:

```json
{
  "mcpServers": {
    "appstoreconnect": {
      "command": "npx",
      "args": ["-y", "@vvlladd/appstoreconnect-mcp"],
      "env": {
        "ASC_KEY_ID": "your-key-id",
        "ASC_PRIVATE_KEY_PATH": "/path/to/AuthKey.p8",
        "ASC_AUTH_MODE": "individual"
      }
    }
  }
}
```

Then ask your agent something like:

> "Prepare version 2.1.0 for my app, validate it's ready for submission, and show me the full release status."

## Configuration

### Environment Variables

| Variable | Description | Required |
|----------|-------------|----------|
| `ASC_KEY_ID` | API key ID | Yes |
| `ASC_PRIVATE_KEY_PATH` | Path to `.p8` private key file | Yes |
| `ASC_ISSUER_ID` | API issuer ID; omit for individual keys | Team keys only |
| `ASC_AUTH_MODE` | Authentication mode: `team` (default) or `individual` | Required for individual keys |

## Multi-Organization Support

Manage multiple App Store Connect teams by setting org-prefixed environment variables:

```bash
ASC_ORG_acme_ISSUER_ID=xxx
ASC_ORG_acme_KEY_ID=yyy
ASC_ORG_acme_PRIVATE_KEY_PATH=/path/to/acme.p8
ASC_ORG_acme_AUTH_MODE=team

ASC_ORG_startup_ISSUER_ID=aaa
ASC_ORG_startup_KEY_ID=bbb
ASC_ORG_startup_PRIVATE_KEY_PATH=/path/to/startup.p8

ASC_DEFAULT_ORG=acme   # optional, defaults to first org alphabetically
```

When multi-org variables are present, single-org variables are ignored. Use `list_orgs` to see configured organizations and `set_default_org` to switch at runtime.
