Heimdall MCP Server

A real agent session over MCP, sped up. The App Store Connect account is a stand-in so the recording can be public - regenerate with vhs assets/demo/demo.tape. It runs locally over stdio via the published package.

People who work with app store connect, apple and ios and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
