RTM MCP Server

A Model Context Protocol (MCP) server for Remember The Milk that provides comprehensive task management functionality through Claude Desktop.

Important consideration before using this code or interacting with this codebase

This application is an experiment in using Claude Code as the primary driver the development of a small, focused app that concerns itself with the owner's particular point of view on the task it is accomplishing.

As such, this is not meant to be what people think of as "an open source project," because I don't have a commitment to building a community around it and don't have the bandwidth to maintain it beyond "fix bugs I find in the process of pushing it in a direction that works for me."

It's important to understand this for a few reasons:

1. If you use this code, you'll be using something largely written by an LLM with all the things we know this entails in 2025: Potential inefficiency, security risks, and the risk of data loss.

2. If you use this code, you'll be using something that works for me the way I would like it to work. If it doesn't do what you want it to do, or if it fails in some way particular to your preferred environment, tools, or use cases, your best option is to take advantage of its very liberal license and fork it.

3. I'll make a best effort to only tag the codebase when it is in a working state with no bugs that functional testing has revealed.

While I appreciate and applaud assorted efforts to certify code and projects AI-free, I think it's also helpful to post commentary like this up front: Yes, this was largely written by an LLM so treat it accordingly. Don't think of it like code you can engage with, think of it like someone's take on how to do a task or solve a problem.

Overview

This MCP server enables Claude to interact with Remember The Milk tasks, lists, and metadata using natural language. It implements most RTM API functionality with user-friendly responses and proper error handling.

Features

✅ Fully Implemented

Core Functionality

• Connection Testing: Verify API connectivity and auth status
• List Management: Create, list, and archive RTM lists
• Task CRUD: Create, read, update, delete tasks with full metadata support

Task Operations

• Task Creation: Create tasks in specific lists with natural language parsing
• Task Completion: Mark tasks complete (handles recurring tasks properly)
• Task Deletion: Permanently delete tasks (stops recurrence)
• Task Moving: Move tasks between lists
• Task Postponing: Postpone due dates

Task Metadata

• Priorities: Set high (1), medium (2), low (3), or no priority
• Due Dates: Set/clear due dates with natural language ("tomorrow", "next Friday", etc.)
• Start Dates: Set/clear start dates with natural language parsing
• Time Estimates: Set/clear time estimates ("30 minutes", "2 hours", etc.)
• Tags: Add and remove tags from tasks
• Task Names: Rename tasks
• Notes: Add, edit, delete, and read task notes
• Locations: Set/clear locations from predefined RTM locations with 📍 display
• URLs: Set/clear task URLs with 🌐 display
• Permalinks: Generate RTM web interface links for tasks

Advanced Features

• Recurrence: Set and clear recurring task patterns
• Subtasks: Create and list subtasks (requires RTM Pro)
• Search & Filtering: List tasks with various filters and search criteria
• Location Management: List predefined locations and set task locations
• Bulk Operations: Move tasks between lists, batch tag operations

⚠️ Known Limitations

Subtasks

• Create Subtask: ✅ Works (requires RTM Pro account)
• List Subtasks: ⚠️ Workaround implementation (RTM API limitation)

Implementation Status

The RTM MCP server now implements comprehensive RTM functionality including:

• ✅ All core task operations (CRUD, metadata, search)
• ✅ Location support with predefined location man
