AI Analysis

●●SolidWizardryDark Horse

Reverse-engineers private Apple APIs to auto-expose app intents as MCP tools. Cool, but requires disabling SIP.

Strengths

•Wire-protocol XPC approach means zero per-app setup—just point at any App Intents bundle
•600 lines of Swift elegantly bridges Apple's internal automation stack to Claude's MCP
•Solves a real macOS automation friction: App Intents exist but aren't accessible to external AI agents

Weaknesses

•Requires disabling SIP and AMFI—fundamentally a research tool, not shippable to users
•Narrow audience: only macOS users with Claude integration workflow needs

Post Description

Action Relay is an MCP server that reads the intent metadata Apple embeds inside every App Intents-enabled .app bundle and exposes them as MCP tools automatically. Execution is done by generating workflows on the fly which means you do not need to create shortcuts beforehand.

This is a proof of concept to bring what I've been waiting for from Apple Intelligence to life.

It requires disabling SIP, AMFI and uses private APIs and entitlements so it is not meant for real world use.

The reverse engineering and development code was done completely with Claude Code. I was very impressed with its willingness to take on this kind of reverse engineering task with no objection.
