Heimdall

Overview

Heimdall is a Model Context Protocol server that exposes every App Store Connect and StoreKit 2 endpoint. It provides 890 tools organized across 13 profiles, which you can narrow down to the 27 most relevant for your workflow. Any MCP-compatible AI assistant can call Heimdall's tools directly, letting the model decide when to use them during conversations or agent runs.

The server runs locally via the npm package @erayendes/asc-mcp, which communicates over stdio. Install it with npx -y @erayendes/asc-mcp. You'll need an App Store Connect API key for authentication. The latest release is v2.3.0, published under the MIT license. Source code and documentation are available at erayendes/app-store-connect-mcp on GitHub, where the project has 47 stars.

Heimdall is listed under File System on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain Heimdall, claim this listing to verify ownership, earn the Verified badge, and keep information current.
