## What it does

The plugin ships an MCP server written in Swift that talks to Apple's EventKit framework. Thirteen tools come with it: list your lists, pull open, completed or all reminders, run a full-text search, ask for today, overdue or scheduled items, and create, update, complete or delete a single reminder. Reminder IDs stay the same across sessions, so the agent does not lose track of a task after a restart.

Every tool carries a read-only or destructive hint, which lets the client run queries on its own and ask before it changes anything. Umlauts, accents, CJK characters and emoji survive the round trip. Nothing goes over the network. The binary is signed and notarized by Apple, so Gatekeeper stays quiet.

Installation goes through the Claude plugin marketplace. Reload Claude after adding the marketplace, otherwise the plugin will not show up. On the first call macOS asks for Reminders access; deny it and the server has nothing to read. This is Mac-only — there is nothing to install on Linux or Windows.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install reminders-for-macos@claude-community
```

## When to use it
- see what is due today
- find a reminder by a fragment of its text
- add a dated task to a specific list
- clear out overdue items
- delete a reminder you no longer need

## Example prompts
- What's on my reminders for today?
- Add buy oat milk to the Groceries list for tomorrow at 6pm.
- Show me everything overdue and mark the Slack reply as done.

Fast, native Apple Reminders access for Claude — works in **Claude Desktop**, **Claude Cowork**, and **Claude Code** (CLI). One signed Swift/EventKit binary, three distribution packages.

Reminder IDs are stable across sessions. A full CRUD round-trip takes under a second on a database with 300+ reminders. Umlauts, accents, CJK characters and emoji pass through unchanged.

## Quick start

You need a Mac (Apple Silicon or Intel) running macOS 11 or later, and Claude Desktop.

1. Download **`apple-reminders.mcpb`** from the [latest release](https://github.com/high5-ventures/apple-reminders-for-claude/releases/latest).
2. Double-click it. Claude Desktop opens an install dialog — click **Install**.
3. Ask Claude something like **"What's on my reminders for today?"**

macOS asks for Reminders access on that first question. Allow it, and Claude can read and change your reminders.

No configuration is needed: the bundle contains the server and the signed binary, and Claude Desktop sets the paths on install.

Updating is the same three steps with the newer `.mcpb`.

## Description

Apple Reminders for Claude gives Claude full CRUD access to your macOS Reminders app. It wraps Apple's native **EventKit** framework in a signed Swift binary that returns stable UUIDs and structured JSON, and ships three ways:

| Target | Artifact | Where to get it |
|---|---|---|
| **Claude Desktop / Cowork** | `.mcpb` bundle | [Releases](https://github.com/high5-ventures/apple-reminders-for-claude/releases) |
| **Claude Code** (CLI) | Plugin with skill | `/plugin marketplace add` against this repository |
| **Any MCP client** | npm package | `npm install -g @high5ventures/apple-reminders-mcp` |

All three ship the same binary and the same 13 tools, so behaviour does not differ between them.

## Features

- **13 MCP tools** covering the full reminder lifecycle: list lists, list reminders (open/completed/all), full-text search, today/overdue/scheduled smart queries, CRUD on individual reminders.
- **Native EventKit** — not AppleScript, not reverse-engineered SQLite scraping.
- **Stable UUIDs** — reminder IDs survive across sessions, unlike AppleScript URIs or CLI positional indexes.
- **Tool safety annotations** — every tool declares `readOnlyHint` / `destructiveHint` so Claude clients can auto-run queries but prompt for mutations.
- **Language-neutral** — the skill matches on intent, not keywords. Works identically in German, French, Spanish, Japanese, etc.
- **Speed** — full CRUD smoke-test completes in under 1 s on 300+ reminders across 10 lists.
- **Signed + notarized** — no Gatekeeper warnings; deployable via MDM.
- **100% local** — no network I/O. See [PRIVACY.md](PRIVACY.md).

## Usage examples

In Claude Desktop and Cowork the tools appear under **Apple Reminders**; in Claude Code the skill loads when you mention reminders. The examples below show the tool calls behind each answer.

### Example 1 — "What's on my plate today?"

> **You:** Was habe ich heute zu tun?
>
> **Claude** (invokes `get_today`):
```
