Quick Start

# 1. Install
npm install -g asc-mcp

# 2. Set credentials (get from App Store Connect > Users and Access > Keys)
export APP_STORE_CONNECT_KEY_ID="YOUR_KEY_ID"
export APP_STORE_CONNECT_ISSUER_ID="YOUR_ISSUER_ID"
export APP_STORE_CONNECT_P8_PATH="/path/to/AuthKey.p8"

# 3. Add to your MCP client config and start using!

Installation

npm (recommended)

npm install -g asc-mcp

Using npx

npx asc-mcp

From Source

git clone https://github.com/SardorbekR/appstore-connect-mcp.git

1. Sign in to App Store Connect
2. Go to Users and Access → Integrations → App Store Connect API
3. Click Generate API Key (or use existing)
4. Select appropriate role (Admin or App Manager recommended)
5. Download the .p8 file - you can only download it once!

Usage Examples

List Your Apps

"Show me all my apps in App Store Connect"

Claude will use list_apps to retrieve and display your apps.

Update App Description

"Update the English description for version 2.0 of MyApp to: 'A revolutionary app that simplifies your daily tasks.'"

Claude will:

1. Find the app using list_apps
2. Get the version using list_app_versions
3. Find the English localization using list_version_localizations
4. Update it using update_version_localization

Add Japanese Localization

"Add Japanese localization to MyApp version 2.0 with description '素晴らしいアプリです' and keywords 'アプリ,便利,簡単'"

Claude will use create_version_localization with locale ja.

Add a Beta Tester

"Add john@example.com as a beta tester to the Internal Testing group for MyApp"

Claude will:

1. Find the app and beta group using list_beta_groups
2. Add the tester using add_beta_tester

Check Version Status

"What's the status of all versions of MyApp?"

Claude will use list_app_versions to show version states (PREPARE_FOR_SUBMISSION, IN_REVIEW, READY_FOR_SALE, etc.)

Security

Credential Handling

• Private keys are never logged or exposed in error messages
• JWT tokens are automatically redacted from any error output
• Issuer IDs (UUIDs) are redacted from logs
• Token caching minimizes key usage (15-min tokens, refreshed at 10 min)

Path Validation

• P8 file paths are validated against directory traversal attacks (.. not allowed)
• Only absolute paths are resolved

Best Practices

1. Never commit credentials - Use environment variables or a secrets manager
2. Restrict API key permissions - Use minimal required role (App Manager for most operations)
3. Rotate keys periodically - Generate new API keys and revoke old ones
4. Secure your .p8 file - Set file permissions to 600 (owner read/write only)

chmod 600 /path/to/AuthKey.p8

Troubleshooting

"Configuration error: APP_STORE_CONNECT_KEY_ID environment variable is required"

Ensure all required environment variables are set:

• APP_STORE_CONNECT_KEY_ID
• APP_STORE_CONNECT_ISSUER_ID
• APP_STORE_CONNECT_P8_PATH or APP_STORE_CONNECT_P8_CONTENT

"Failed to read private key"

1. Verify the path in APP_STORE_CONNECT_P8_PATH is correct and absolute
2. Check file permissions: ls -la /path/to/AuthKey.p8
3. Ensure the file is a valid .p8 from Apple (starts with -----BEGIN PRIVATE KEY-----)

"Authentication failed"

This usually means:

1. The API key was revoked in App Store Connect
2. The Key ID or Issuer ID doesn't match the .p8 file
3. The .p8 file is corrupted or incomplete

"Rate limit exceeded"

The server includes built-in rate limiting (50 requests/minute). If you hit Apple's limits:

1. Wait for the indicated retry time
2. Batch your operations when possible
3. The server automatically retries with exponential backoff

Tools Not Appearing in Claude

1. Verify the server is running: check Claude Desktop logs
2. Ensure the config file path is correct for your OS
3. Restart Claude Desktop after config changes
