Morsel

The storehouse your AI fills. Morsel is a MCP-first, camera-first food tracker. There is no chat inside the app — you log by chatting with your existing assistant (Claude, ChatGPT) and uploading a photo; the assistant's agent reads the photo, calls Morsel's MCP tools, and writes structured food data to your store. Morsel is the data store + dashboard + agent skill; the intelligence lives in the agent you already use.

Why this exists

People chat with Claude/ChatGPT every day but can't keep context or structured data. Generic calorie apps re-implement their own AI, locked inside a silo.

Morsel flips it:

• No in-app chat. The app has no AI brain and no chat UI.

• MCP-first. The app is a Model Context Protocol server + a data store. Your agent connects over MCP and knows the exact data structure to write.

• Camera-first. You upload a food photo in your chat app; the agent's vision estimates macros and calls log_meal.

• Dashboard. A native iOS app (or PWA) renders your history, totals, and goals — reading the same store the agent writes.

Architecture (one line)

Supabase (Postgres + auth + RLS + storage) ↔ thin remote MCP server ↔ your agent (Claude/ChatGPT) and ↔ native iOS dashboard. One store, two clients.

Docs

• ARCHITECTURE — components, data flow, auth, backend decision

• DATA_MODEL — tables, enums, RLS

• MCP_TOOLS — the tool contract (input/output schemas) — what the agent writes

• TARGETS — computed calorie/macro goal from body metrics

• IN_CHAT_RENDER — Tier-1 snapshot rendering inside Claude/GPT

• ROADMAP — milestones

• CLAUDE.md — context for any agent working in this repo (AGENTS.md is a symlink to it)

Status

Design scaffold with quality guardrails in place (strict TypeScript, anti-slop ESLint + SwiftLint, CI on every PR). Working name morsel (rename freely — it's a folder + a README).
