Use Reanthesis

use-reanthesis

Connect your AI to Reanthesis, spaced repetition for serious exams.

Your AI reads your lecture notes, drafts sharp flashcards, and files them into your decks through the hosted MCP server at https://reanthesis.com/mcp. You open Reanthesis and study. There is nothing to install or run: connecting is a URL and one Allow tap.

Connect

| Client | Setup | | --- | --- | | Claude (claude.ai, desktop, iOS) | Settings → Connectors → Add custom connector → https://reanthesis.com/mcp | | ChatGPT | Settings → Connectors (developer mode) → https://reanthesis.com/mcp | | Claude Code | claude mcp add --transport http reanthesis https://reanthesis.com/mcp | | Codex CLI | codex mcp add reanthesis --url https://reanthesis.com/mcp | | VS Code · Copilot | Add an HTTP MCP server with the same URL |

Your browser opens the Reanthesis authorize screen; sign in if needed and tap Allow. You need an existing Reanthesis account — a connector can never create one, and it can never touch billing or account settings.

Plugins

For clients with a plugin system, the plugin bundles the connector and the card-craft skill together, so one install is a complete setup.

Claude Code:

/plugin marketplace add Reanthesis/use-reanthesis
/plugin install reanthesis@reanthesis

Codex CLI: codex plugin marketplace add Reanthesis/use-reanthesis, then codex plugin add reanthesis@reanthesis and start a new thread. Copilot CLI uses the same two /plugin commands as Claude Code.

The skill

[skills/reanthesis](skills/reanthesis/SKILL.md) teaches an AI the craft before it touches a tool: read the whole source, check what already exists, propose the batch, then create. Two focused references cover the craft — [creating cards](skills/reanthesis/references/creating-cards.md) and [waking dormant cards](skills/reanthesis/references/waking-dormant-cards.md), the loop that keeps a growing collection studyable. Hosted clients without skills (claude.ai, ChatGPT) receive the same guidance from the server itself at connection time.

What your AI can do

The server exposes 13 tools, scoped to card tending:

• whoami, study_status — connection health and the study dashboard.
• list_decks, create_deck, list_cards — navigate the collection.
• create_card, create_cloze, update_card, delete_card — author notes,

including {{c1::...}} cloze deletions.

• wake_cards, rest_cards, find_tags — move material between active

(in the study queue) and dormant (paused, progress kept), by tag, deck, or card.

• upload_image — attach diagrams that are themselves the study content.

The full contract is in [docs/mcp-tools.md](docs/mcp-tools.md).

Auth and privacy

Connecting uses OAuth 2.1 (authorization code + PKCE), discovered automatically from the server URL. Approval mints an opaque connector token, stored hashed server-side, valid 180 days, revoked by a password reset. The token is scoped server-side, deny by default: it can tend cards and read study state, and the API refuses everything else — account, billing, membership, exports, imports, and review submission. Your AI builds and tends cards; only you study them.

Inference stays yours: your AI reads your material with your subscription. Reanthesis stores cards and study state, schedules with FSRS, and adds no third-party inference or analytics to this integration. Details in [docs/auth.md](docs/auth.md).

Roadmap

• Connector-registry listings, so adding Reanthesis becomes a toggle instead

of a URL.

• OAuth refresh tokens.
• Image-occlusion and cluster tools.
• Bulk import.
