Building a Daily Chinese Diary Habit with Notion MCP + Claude

This is a submission for the Notion MCP Challenge What I Built I built an automated workflow for my daily Chinese learning habit called "中国語3行日記" (3-Line Chinese Diary) . Every day, I write a 3-sentence Chinese diary entry based on a daily theme, get it corrected by Claude, and post it to Bluesky — all without leaving Claude's chat UI. The system is powered by Notion + Claude MCP + GitHub Actions : Notion stores the daily themes (Questions DB) and my answers with correction notes (Answers DB) Claude MCP fetches the day's theme, corrects my Chinese, records the answer and notes back to Notion, and helps me analyze my writing patterns over time GitHub Actions runs a daily cron job at 21:00 JST to automatically post scheduled answers to Bluesky As of today, I've kept this habit going for over 225 days.
