Dayfold: learning MCP through a shared todo app

A simple todo app for experimenting with an MCP server, agent authentication and user-controlled access to shared task lists.

Problem

I wanted to build an MCP server and explore how AI agents could use it to manage tasks through automations and scheduled workflows. A todo app gave me a simple, practical place to learn.

My role

I built Dayfold and its MCP server so people and agents could work on the same shared task lists. Agents can create, reschedule, complete and reopen tasks through MCP.

Decision

I used WorkOS AuthKit for user sign-in and WorkOS Connect for agent authentication. Users choose which projects each agent can access, give it read-only or edit permissions, and revoke access anytime.

Result

Dayfold is available to try as a shared task list for people and agents. Unfinished tasks carry over to today based on the project's time zone. I kept the task list simple on purpose so I could focus on giving agents useful access while keeping the user in control.
