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 | $0.01289 | $0.01289 |
| Opus 5 | $0.00645 | $0.00645 |
| Sonnet 5 | $0.00258 | $0.00258 |
| Haiku 4.5 | $0.00129 | $0.00129 |
Grade A, and why
zk-mcp 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 12d 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.

CLAUDE.md
プロジェクト概要
これはzkプレーンテキストノート取りシステムと統合するMCP(Model Context Protocol)サーバーです。このサーバーはLLMがzkで管理されたナレッジベースにアクセスしクエリを実行するためのツールを提供します。
主要コマンド
開発
make run- ZK_DIR=.でMCPサーバーを開発モードで実行make format- ruffを使用してコードをフォーマット(インポート + フォーマット)make lint- ruffでリント、mypyで型チェックを実行make test- テストを実行(開発依存関係のpytestを使用)make pre-commit- formatとlintの両方を実行(コミット前推奨)
パッケージ管理
uv add <package>- ランタイム依存関係を追加uv add --dev <package>- 開発依存関係を追加uv run <command>- 仮想環境でコマンドを実行
アーキテクチャ
コアコンポーネント
-
server.py - FastMCPを使用したメインのMCPサーバー実装
- 5つのMCPツールを定義:
get_note_paths,get_linking_notes,get_tags,get_note,create_note zkCLIとのやり取りにsubprocessを使用- 全ツールはPydanticモデルを使用してJSONレスポンスを返す
- 5つのMCPツールを定義:
-
tools/ - 各MCPツールの実装
get_note_paths.py- 複雑なフィルタリングでノートをクエリget_linking_notes.py- ノートのリンク関係を分析get_tags.py- 利用可能なタグをリストget_note.py- 特定のノートの内容を読み取りcreate_note.py- 新しいノートを作成models.py- APIレスポンス用のPydanticデータモデル
-
settings.py - pydantic-settingsを使用した設定
zk_dir- zkノートディレクトリへのパス(ZK_DIR環境変数で設定)
MCPツール
get_note_paths()
複雑なフィルタリングでノートをクエリ:
include_str- コンテンツまたはファイル名に含まれる文字列でフィルタinclude_str_operand- 複数の文字列フィルタの論理演算子(AND/OR)exclude_str- 特定の文字列を含むノートを除外include_tags- タグでフィルタinclude_tags_operand- 複数のタグフィルタの論理演算子(AND/OR)exclude_tags- 特定のタグを持つノートを除外
get_linking_notes(path)
特定のノートのリンク関係を分析:
link_to_notes- 指定されたノートがリンクしているノートlinked_by_notes- 指定されたノートにリンクしているノートrelated_notes- 指定されたノートと関連するノート
get_tags()
ノートブック内の利用可能なタグをすべてリスト
get_note(path)
特定のノートの完全なコンテンツを読み取り
create_note(title, directory)
新しいノートを作成(オプションでディレクトリを指定)

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.

zk-mcp CLAUDE.md is an instructions file published in the GitHub repository koei-kaji/zk-mcp (1 stars, last pushed 12mo ago), licensed MIT. It adds 1,289 tokens to every session, about $0.0064 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
