I built an MCP server that lets Claude read my study data

tl;dr — Shiori is an open-source AI study app (React + Gemini). I added a Model Context Protocol server so you can ask Claude Code things like "what assignments are due this week?" and get real answers from your actual data.

The problem

I was using Claude Code to help me study, but it had no idea what I was actually studying. I'd have to paste my notes, deadlines, and grades into the chat every time.

What I wanted: Claude to already know my study context.

What Shiori does

Shiori is a full study companion: assignments, grades, GPA predictor, AI flashcard generation, spaced repetition, AI quiz generator, habit tracker, focus mode (Pomodoro), leaderboard, and a syllabus importer that extracts all assignments from a PDF/text dump.

It runs entirely in the browser — no server needed for the core features. Data lives in localStorage. You can try it at (no account)
