IP-MCP: Instructions file for Claude Code

CLAUDE.md

IP-MCP CLAUDE.md is an instructions file for Claude Code from kitepon/IP-MCP. It costs 3,124 tokens per session, scanned B, original, MIT.

A project instruction document for Claude Code, covering the current state, goals, architecture rules, deployment setup, and development plans. Claude Code reads this kind of file to understand how to work in the repository.

In plain words
What is it for?
Use it to document a patent-information service, its tools, authentication, deployment path, tests, completed phases, and future features.
Why use it?
It gives the coding agent project-specific context and boundaries, reducing guesses about the system and its unfinished work.

Instructions file for Claude Code

Written for Claude Code: SessionStart hook event. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is kitepon/IP-MCP's own configuration. It tells Claude Code how to work on IP-MCP itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything IP-MCP configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

IP-MCP CLAUDE.md scanned grade B with 1 finding 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

現状

Phase 1A / 1B / 1.x 完了済（2026-05-01 時点）。リポジトリには動作する実装が入っている:

  • src/ip_mcp/tools_official/ — 12 ツール (番号変換 / 経過情報 / 登録 / 引用 / 関連出願 / 出願人 / 書類 / J-PlatPat URL / OPD / 全件取得)
  • src/ip_mcp/tools_external/ — 1 ツール (Google Patents キーワード検索、独立実装)
  • src/ip_mcp/auth/ — OAuth 2.1 サーバー (DCR + PKCE + マスターパスワード認可、SqliteOAuthProvider で SQLite 永続化)
  • Dockerfile / docker-compose.yml — ./cache, ./logs, ./data の 3 ボリューム
  • tests/ — 45 テスト、全緑

公開構成: ipmcp.<domain> → Cloudflare Edge → Cloudflare Tunnel (cloudflared が自宅から outbound) → Caddy (CF Origin Cert で end-to-end TLS) → <DEPLOY_HOST>:8765 → Docker コンテナ。CF Tunnel が outbound 接続でエッジに繋がる方式のため、ホームルーターのポート開放もヘアピン NAT 回避も不要。LAN 内/外を問わず CF エッジ経由で同じ URL に届く。

Phase 1.5 完了: OAuth 永続化 / ヘアピン NAT 回避 / アクセスログ JSONL (logs/access.jsonl) + 集計スクリプト (scripts/summarize_logs.py) / マスターパスワード rotate 手順 (OPERATIONS.md)。 Phase 2 (未着手): 拒絶理由通知書 PDF 構造化、AI レビューパイプライン、EPO OPS / WIPO PATENTSCOPE 補完。

PLAN.md は設計計画書として継続維持中（§11 段階表に進捗、§12 リスク表で完了済リスクを取り消し済）。

このプロジェクトが目指すもの

特許庁の公式「特許情報取得API」(基底 https://ip-data.jpo.go.jp) を包む Python 製 MCP (Model Context Protocol) サーバー を作り、LLM クライアントから呼べるようにする。<DEPLOY_HOST>（自宅 LAN, SSH ユーザー <SSH_USER>）の Docker 上で常駐させ、Claude Desktop / Claude Code から HTTP+SSE で利用する。

譲れないアーキテクチャ規則

ユーザーから明示的に指示された方針。これを破ったら退行 (regression)。逸脱の前に必ず質問すること。

  1. データソース間の暗黙のフォールバック禁止。公式 JPO API の呼び出しが失敗 (not_found / レート上限 / 一時障害) しても、Google Patents 等の外部ソースに自動で切り替えてはならない。失敗は失敗としてそのまま返し、別ツールを呼ぶかどうかは LLM 側に判断させる。
  2. ツールは完全に分離された 2 カテゴリに分ける:
    • tools_official/ — 公式 JPO API を叩く。ツール名は jpo_* で始める。レスポンスは {"source": "jpo_official", ...}。
    • tools_external/ — 非公式ソース (キーワード検索用の Google Patents XHR 等) を叩く。ツール名は external_* で始める。レスポンスは {"source": "google_patents_unofficial", ...}。
    • tools_official/ から tools_external/ への import は禁止（逆も同様）。これは完了基準として強制する。
  3. 同一ツール内で許される再試行は次の 2 つだけ: 401/期限切れ時のトークン再取得、JPO の statusCode 303（一時的な高負荷）に対する指数バックオフ。どちらも同一データソース内に閉じる。
  4. すべてのツール description は冒頭に Source: 行を必ず置き、データの出所が公式か非公式かを LLM が判別できるようにする。レスポンスペイロードにもトップレベルに source フィールドを必ず含める。

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.
