"Teaching Claude to remember."
Claude Code sessions are temporary. Close the window, and everything you discussed - the decisions you made, the tasks you identified, the context you built up - vanishes. Next session, you start from scratch.
I use Remember The Milk obsessively. Have for years. It's the one productivity tool that never got replaced. So when I needed persistent memory for Claude Code, the solution was obvious: make RTM the external brain.
What It Does
milk-mcp is an MCP (Model Context Protocol) server that connects Claude Code to your Remember The Milk account. For each project, it creates five lists:
- TODO - what's active right now
- Backlog - deferred work
- Bugs - logged with reproduction steps
- Decisions - architectural choices with the reasoning that led to them
- Context - the handoff note from last session
How It Works
Starting a session is just: "Let's work on [project]." Claude calls rtm_session_start, reads your open TODOs and the latest context note, and picks up where you left off.
Ending a session is just: "Let's wrap up." Claude writes a handoff summary, saves it to RTM, and next-you will actually know what happened.
The Decisions list is the part I use most. I can't count the number of times a past-me made an architectural call that present-me thought was wrong, only to dig into it and find there was a very good reason. Now Claude logs those decisions with rationale, and neither of us has to relitigate them.
Available Tools
The MCP server exposes these tools to Claude:
rtm_setup_project- Create the five standard lists for a new projectrtm_session_start- Load context and TODOs at session startrtm_session_end- Write handoff note for next sessionrtm_add_task- Add a TODO itemrtm_add_backlog- Add a backlog itemrtm_add_bug- Log a bug with detailsrtm_complete_task- Mark a task as donertm_log_decision- Record an architectural decisionrtm_get_todos- List open TODO itemsrtm_get_bugs- List open bugsrtm_get_decisions- Review past decisionsrtm_get_context- Read the last handoff notertm_list_projects- List all milk-mcp projects
Setup
You'll need a Remember The Milk account (free tier works fine) and API credentials. No cloning required - everything runs via npx.
# Authenticate with RTM
npx milk-mcp auth
# Add the MCP server to Claude Code
claude mcp add milk-mcp -- npx milk-mcp
# Restart Claude CodeThat's it. Five minutes, and Claude has persistent memory.
Automatic Session Management
For hands-free session handling, add instructions to your ~/.claude/CLAUDE.md file. Claude will automatically start sessions when you begin working and save context when you wrap up - using the current folder name as the project name.
This means you can just say "let's wrap up" and Claude knows to call rtm_session_end with a summary of what was accomplished. Next time you open the project, it picks up right where you left off.
Why RTM
Partly because I already had the account. But also because the RTM API is genuinely solid, the free tier is more than enough, and there's something satisfying about a 20-year-old task manager becoming the external brain for a state-of-the-art AI coding assistant.
Also, the name was right there. You can't not call it milk-mcp.
