Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00034 | $0.00492 |
| Opus 5 | $0.00017 | $0.00246 |
| Sonnet 5 | $0.00007 | $0.00098 |
| Haiku 4.5 | $0.00003 | $0.00049 |
Grade B, and why
setup 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 9d 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.
chmod 600 ~/.fugaku/fugaku.pem What it actually says
富岳MCP セットアップ
このプラグインは富岳の X.509 クライアント証明書を使う。証明書を ~/.fugaku/fugaku.pem
（PEM形式・秘密鍵結合）に置けば動作する。以下を手伝うこと。
手順
- ユーザーに証明書の場所を尋ねる（HPCI/R-CCS発行の
.p12、または変換済み.pem）。 - PEMへ変換して配置（
.p12の場合。パスフレーズはユーザーが入力）:
既に PEM（cert+key 結合）ならmkdir -p ~/.fugaku openssl pkcs12 -in <p12> -nodes -out ~/.fugaku/fugaku.pem chmod 600 ~/.fugaku/fugaku.pem~/.fugaku/fugaku.pemへコピーしてchmod 600。 /reload-plugins（またはclaudeを再起動）してMCPサーバを有効化。- 疎通確認:
cluster_statusを呼び{"status":"OK","machine":"computer"}が返れば成功。account_infoで自分のアカウント/HOME/グループも確認する。
注意
- 証明書には秘密鍵が含まれる。権限は 600、共有・コミットは厳禁。
- 別パスの証明書を使いたい場合は
~/.fugaku/fugaku.pemにシンボリックリンクを張ってもよい。 - 繋がらない場合は
/mcpで接続状態・エラーを確認（証明書パス・有効期限・ネットワークはVPN不要）。使い方はfugaku_helpを参照。
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.

setup is a skill published in the GitHub repository RIKEN-RCCS/fugaku-mcp (3 stars, last pushed 16d ago), licensed MIT. It adds 34 tokens to every session and 492 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
