Asc MCP

App Store Connect MCP Server

A local Model Context Protocol server for the App Store Connect API.
Manage apps, builds, TestFlight, reviews, and more from Codex, Claude, and other MCP clients on macOS.

Overview

asc-mcp is a Swift-based MCP server that connects a local macOS MCP client to the App Store Connect API. It exposes 502 tools across 33 App Store tool domains + 2 core domains, enabling you to automate iOS and macOS release workflows through natural language.

Configuration examples are included for Codex, Claude Code, Claude Desktop, Gemini CLI, VS Code with GitHub Copilot, Continue, Cursor, and Devin Desktop (formerly Windsurf). Client configuration is documented; release CI verifies installation, MCP initialization, and tool discovery on macOS rather than launching every third-party client.

Key capabilities

• Release and metadata — versions, localizations, builds, review submissions, phased rollout, and Xcode Cloud
• TestFlight and uploads — beta groups, testers, feedback, recruitment, build delivery, processing, and export compliance
• Monetization — in-app purchases, subscriptions, pricing, availability, offer codes, and promotional offers
• Marketing — screenshots, previews, custom product pages, product page optimization, and promoted purchases
• Accounts and provisioning — multiple App Store Connect teams, users, bundle IDs, devices, certificates, profiles, and capabilities
• Feedback and operations — customer reviews, webhooks, accessibility declarations, analytics, metrics, and diagnostics
• Safer automation — read-only mode, confirmation safeguards, strict pagination, and mutation recovery guidance
• Auditable API coverage — a versioned Apple OpenAPI contract and release-time drift checks

Platform Support

asc-mcp is a local stdio server: the MCP client starts it on the same computer. A client being available on Linux or Windows does not make this Swift server cross-platform.

Environment	Status	Notes
macOS 15.6+ with Xcode 26.x	Recommended	Release CI specifically uses GitHub's macOS 15 runner with Xcode 26.2
macOS 14.0-15.5	Declared deployment target only	Build and runtime are unverified; a separately installed Swift 6.2+ toolchain may be needed
Linux	Not supported yet	Porting work and Linux CI are not complete
Windows	Not supported	Current source dependencies and Swift MCP stdio transport are not Windows-compatible

See Apple's Xcode system requirements for the macOS versions supported by each Xcode release.

Web and cloud sessions do not automatically inherit a local MCP configuration. Run the MCP client locally on a compatible Mac, or use a client feature that explicitly keeps execution on that Mac.

Quick Start

The recommended setup stores App Store Connect credentials once in a private local file. MCP clients then need only the path to the asc-mcp executable.

1. Install asc-mcp

brew install mint
mint install zelentsov-dev/asc-mcp@v4.1.6
~/.mint/bin/asc-mcp --version

2. Create an App Store Connect API key
