lab-notebook-mcp

Version: 0.1.0 (Phase 1、 2026-08-17)

測定の一次資料を永続化する MCP サーバー。 chat-Claude 2026-08-17 「新しいアイデア」 arc の 「実験ノート MCP」 提案を independent MCP として 実装。 設計詳細は docs/design.md 参照。

Design 原則 (§5 セキュリティ設計 + §3.4 append-only)

  1. Append-only: 削除ツール なし、 訂正は supersede

  2. モード gating: ro では 書き込み tool を 登録自体しない + SQLite ro URI で 二重防御

  3. 任意 SQL 禁止: execute_sql 系 意図的に 提供しない

  4. 外部由来テキスト は でラップ: prompt injection 対策

  5. 測定器に触らない: benchtop の責務、 本 server は DB layer のみ

  6. アーティファクト中身返さない: メタデータ + path のみ

Quick start

pip install -e ".[dev]"
pytest                     # 全 test 通過確認

Cross-pollination 関連 (Rei stack)

  • benchtop v0.4.0 (2026-08-17): 実験ノート features (subject/env/mystery_id + find_similar_sessions + regression_check) が 本 project と responsibility overlap。 使い分け 推奨:

    • benchtop v0.4.0: quick session-level notes (単発 session に メタデータ付ける)

    • lab-notebook-mcp: structured multi-session records (experiment × run × dut × condition × measurement × artifact × baseline を SQL schema で 永続化、 professional lab notebook 用途)

  • Rei-Automator STEP 1340 audit-log.ts (2026-08-17): hash chain primitive origin、 本 project は SQLite WAL + append-only + supersede で 別方式 の integrity 保証
