intents-mcp Enables macOS App Intents as MCP Tools for AI Agents

Bridging macOS Intents to AI Agents

intents-mcp is a Swift CLI that scans macOS App Intents metadata to expose native system actions (such as Reminders, Calendar, and Notes) as MCP tools for AI agents. The tool allows users to selectively enable specific actions, wrapping them in signed Shortcuts that can be served to clients like Claude Code, Codex, or any MCP-compatible agent.

Scope and Limitations

A census of the tool revealed 1,304 available App Intents on a standard Mac, though none are accessible to agents by default. Currently, only the "simple" tier of actions is supported; operations that require matching existing entities (like editing a specific note) are disabled due to safety concerns regarding incorrect lookups. The tool requires macOS 26+ and is optimized for Apple Silicon, with Intel Macs requiring a source build.

Privacy and Security Model

The implementation relies exclusively on public APIs, avoiding private frameworks or SIP (System Integrity Protection) hacks. No system actions are exposed until explicitly enabled by the user. Destructive or sensitive actions (delete, send, buy, share) require an additional flag. While all calls are logged locally, the signing process for Shortcuts involves Apple’s iCloud validation, meaning wrapper metadata is processed by Apple, though user arguments remain local.
