Sunsamagotchi

ESP32 · e-paper · MCP · Open source

A small desk companion built on an M5Stack ESP32. It shows your Sunsama tasks for the day, lets you check them off with a button press, and can start a timer for the current task — all synced back to Sunsama in real time.

No unlocking your phone. No opening a browser tab. No "while I'm here I might as well check…" Just a screen that tells you what to do next.

How it works

The device talks directly to api.sunsama.com/mcp over HTTPS using the MCP protocol (JSON-RPC 2.0) — the same surface AI assistants use, minus the AI. It fetches your tasks, events, and active timer, and lets you interact via hardware buttons.
