Inside a ChatGPT Work life planner built on MCP, Cloudflare D1, and TRMNL

The author outlines the runtime architecture behind a personal “Life Planner” built with ChatGPT Work, Codex, Cloudflare, MCP, and TRMNL.
Architecture highlights
- ChatGPT Work runs a daily scheduled planner and supports manual edits.
- A custom MCP worker exposes read/write tools for preferences, plans, and agenda data.
- Google Calendar provides event context.
- Cloudflare D1 stores shared planning state, while KV handles OAuth registrations, auth codes, and tokens.
- A separate dashboard worker serves a PWA with day and 3-day views.
- A TRMNL cloud integration renders a compact read-only projection to an e-ink display.
The post says the project was driven entirely by Codex, and that Cloudflare’s agent plugin was especially useful for building the infrastructure.
