Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00967 | $0.00967 |
| Opus 5.5 | $0.00387 | $0.00387 |
| Sonnet 5.5 | $0.00193 | $0.00193 |
| Haiku 4.5 | $0.00097 | $0.00097 |
Grade A, and why
mcp-apps-todo CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
MCP Apps を活用した Todo アプリケーション。Claude Desktop / Claude Code / VS Code から MCP 経由で Todo を操作でき、会話内にインタラクティブな UI が表示される。
プロジェクト概要
- MCP Apps Todo — MCP (Model Context Protocol) のリモートサーバーとして動作し、MCP Apps 拡張により会話内に埋め込みUIを提供する Todo アプリ
- 学習・練習用リポジトリ。認証・認可は未実装
技術スタック
- フレームワーク: React 19 + TanStack Start (SSR)
- MCP:
@modelcontextprotocol/sdk+@modelcontextprotocol/ext-apps - DB: Cloudflare D1 (SQLite) + Drizzle ORM
- ホスティング: Cloudflare Workers
- ビルド: Vite 7 + Bun
- UI: Tailwind CSS v4 + shadcn/ui
ディレクトリ構成
mcp/ → MCP サーバー (ツール定義・ハンドラー)
mcp-ui/ → MCP 埋め込み UI (単一 HTML にビルド)
src/server.ts → Cloudflare Worker エントリポイント (/mcp と Web UI のルーティング)
src/db/ → Drizzle ORM スキーマ・DB 初期化
src/lib/ → DB 操作関数・TanStack Server Functions
src/routes/ → ファイルベースルーティング
src/components/→ React コンポーネント (TodoList, TodoItem, AddTodo, Header)
drizzle/ → DB マイグレーション
開発コマンド
bun install # 依存関係インストール
bun run dev # 開発サーバー起動 (localhost:3000)
bun run build # MCP UI + メインアプリのビルド
bun run deploy # Cloudflare Workers にデプロイ
bun run test # テスト実行
bunx wrangler d1 migrations apply mcp-todo-db --local # ローカル DB マイグレーション
MCP エンドポイント
- ローカル:
http://localhost:3000/mcp - 本番:
https://mcp-apps-todo.starry-night.dev/mcp - トランスポート: Streamable HTTP (セッションレス)
MCP ツール一覧
| ツール | 説明 |
|---|---|
list_todos |
Todo 一覧取得 (username, status?) |
add_todo |
Todo 追加 (username, title, description?) |
update_todo |
Todo 更新 (id, username, title?, description?) |
complete_todo |
完了/未完了トグル (id, username) |
delete_todo |
Todo 削除 (id, username) |
全ツールに _meta.ui.resourceUri が付与され、MCP Apps 対応クライアントで UI が表示される。
アーキテクチャの要点
src/server.tsでパス/mcpを MCP ハンドラーに、それ以外を TanStack Start に振り分け- MCP サーバーはリクエストごとにインスタンスを生成 (セッションレス)
mcp-ui/はvite-plugin-singlefileで単一 HTML にビルドし、?rawで MCP サーバーに埋め込み- MCP UI は
@modelcontextprotocol/ext-apps/react-with-depsのuseApp()で MCP クライアントと通信 - Web UI は
useOptimistic()によるオプティミスティック更新で即時反映
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
