Does create_reminder support due dates and times?

Yes. You can use natural language like "tomorrow at 9am" or "next Friday," and the tool parses it into a proper due date on the reminder so Reminders.app fires a notification.

Which Reminders list does the reminder go into?

By default it goes into your default Reminders list, but you can tell the AI to use a specific list (for example "add it to my Work list") and it will target that one.

Will the reminder sync to my iPhone?

Yes. create_reminder writes to the real Reminders.app on your Mac, so anything created syncs through iCloud to your iPhone and iPad like any reminder you'd add by hand.

Do I need an API key or account?

No. LMCP is free and runs natively on your Mac with no API keys and no cloud account. The AI talks to the local server and the reminder is created on-device.

Create Reminders on Mac with AI — create_reminder

The create_reminder tool lets an AI assistant add a reminder straight into Apple's Reminders.app on your Mac — no copy-paste, no opening the app. You just type what you need in plain English and the reminder appears in your real Reminders list, with title, due date, and list, ready to sync across your iPhone, iPad, and Mac via iCloud.

A concrete example of what you'd type to your AI: "Remind me to call the dentist tomorrow at 9am." The assistant calls create_reminder, sets the title, parses the natural-language due date, and drops it into your default list — done in one sentence.

Which AI agents work?

LMCP exposes 150+ tools over the Model Context Protocol, so any MCP-capable assistant can use create_reminder:

Desktop clients — Claude Desktop, Cursor, VS Code (GitHub Copilot), Windsurf, and Zed auto-configure through a local stdio connection. They talk to the LMCP server running on your Mac directly, with nothing leaving the machine.
Web AIs — ChatGPT, Claude.ai (web), Grok, and Perplexity connect through the LMCP Cloud Relay connector, which securely tunnels their requests to the server on your own Mac.

Whichever you use, the reminder is created locally in your real Reminders.app.

Automation

The real power shows when create_reminder chains with other LMCP tools. The AI can read an email and turn its action item into a reminder, scan your calendar and create a reminder to prep before a meeting, or pull a deadline from a Note and schedule a nudge. Because all 150+ tools share one local context, you can say "Check my inbox for anything urgent and remind me to follow up this afternoon" and the assistant reads the mail, decides what's urgent, and creates the reminders in one flow.

Context

The AI isn't guessing — it works with your real Mac data. It sees which Reminders lists you actually have, your existing reminders, your calendar, and your contacts. So when you say "remind me to send Maria the contract before our Friday call," it can resolve who Maria is, find the Friday event, and set the timing correctly. No manual setup, no exported spreadsheets — it reads the live state of your apps.

Productivity

Capturing a task normally means breaking focus: switch to Reminders, click new, type a title, set a date, pick a list. With create_reminder you stay in your conversation and offload it in a sentence. Over a day of meetings, emails, and quick thoughts, that's dozens of context switches saved. Teams that triage email or plan sprints through their AI can turn entire threads into a tidy reminder list in seconds instead of minutes.

Privacy & GDPR

Everything runs locally on your Mac. LMCP is a native macOS MCP server — your reminders, dates, and list names never touch a cloud server and nothing is stored remotely. There are no API keys to manage and no third-party account. The tool simply asks macOS to write to Reminders.app, the same as if you'd typed it yourself. That makes LMCP GDPR-compliant by architecture — there's no data processor in the middle because there's no middle.
