API

The server exposes the following MCP tools for interacting with Apple Reminders:

getLists

Returns all reminder lists.

getReminders

Returns reminders from a specific list.

  • Parameters:

    • listName (required): The name of the reminder list

createReminder

Creates a new reminder.

  • Parameters:

    • listName (required): The name of the reminder list

    • title (required): The title of the reminder

    • dueDate (optional): The due date for the reminder (ISO format: "YYYY-MM-DDTHH:MM:SS.sssZ")

    • notes (optional): Notes for the reminder

completeReminder

Marks a reminder as completed.

  • Parameters:

    • listName (required): The name of the reminder list

    • reminderName (required): The name of the reminder to complete

deleteReminder

Deletes a reminder.

  • Parameters:

    • listName (required): The name of the reminder list

    • reminderName (required): The name of the reminder to delete

How It Works

This MCP server uses AppleScript to interact with the Apple Reminders app on macOS. It provides a standardized interface for AI assistants to manage reminders through the Model Context Protocol.

Development

This project uses TypeScript and the MCP SDK. To extend functionality, modify the tools in src/index.ts and the AppleScript functions in src/reminders.ts.

Requirements

  • macOS (required for Apple Reminders integration)

  • Node.js 16+

  • Apple Reminders app configured with at least one list

TDQS

D1/5.0
Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Tool has no description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness1/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Tool has no description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has no description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Tool has no description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

Tool has no description.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Tool has no description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

C2/5.0
Disambiguation5/5

Each tool has a clearly distinct purpose with no overlap: completeReminder, createReminder, and deleteReminder handle different lifecycle actions on reminders, while getLists and getReminders are distinct read operations for lists and reminders respectively. The naming makes it immediately clear what each tool does without ambiguity.

Naming Consistency5/5

All tools follow a consistent verb_noun pattern with camelCase styling: completeReminder, createReminder, deleteReminder, getLists, getReminders. The naming is perfectly predictable and follows the same convention throughout the entire set.

Tool Count4/5

Five tools is a reasonable number for a reminders server, covering core CRUD operations and list management. It's slightly lean but appropriate for the domain, though an updateReminder tool would make it more complete. The count is well-scoped without being excessive.

Completeness3/5

The tool set covers create, read (getReminders), and delete operations for reminders, plus list management (getLists) and completion (completeReminder). However, there's a notable gap: no updateReminder tool to modify existing reminders, which is a common operation in reminder systems. This missing functionality could cause agent workarounds.
