Blitz is a macOS application that provides MCP (Model Context Protocol) integration for App Store Connect, allowing AI agents to control iOS app submission workflows. It gives Claude Code or any MCP client full control over simulator execution, in-app purchase configuration, screenshot uploads, and App Store review submissions. The tool wraps the App Store Connect API in an AI-accessible interface, making the traditionally manual App Store submission process automatable through natural language commands to an LLM agent.
