Heimdall (App Store Connect MCP)

Overview

Heimdall is an MCP server covering the App Store Connect API and the App Store Server API (StoreKit 2), generated from Apple's own OpenAPI specification. It runs locally on your machine and organises its tools into profiles, so you only switch on what you need. It asks for confirmation before risky changes such as price changes, Admin access or deletions.

Features

• 927 tools by the project's count: the 888 operations Apple hasn't deprecated, plus 39 hand-written ones
• Profiles for apps and metadata, TestFlight, subscriptions, pricing, reviews, Game Center, Xcode Cloud, provisioning and reports
• Runs locally rather than as a remote server
• Asks before risky changes
• Designed to work alongside Fastlane rather than replace it
• Guided setup in the browser or terminal

Requirements

• Node.js 20.19 or later
• An App Store Connect API key

Install
