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 | $0.00028 | $0.02665 |
| Opus 5 | $0.00014 | $0.01333 |
| Sonnet 5 | $0.00006 | $0.00533 |
| Haiku 4.5 | $0.00003 | $0.00266 |
Grade A, and why
mcp-config 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 5d 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 — 333 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mcp-config
MCP サーバーの追加・一覧・削除を対話形式で行う。
全ての設定は .claude/settings.json のプロジェクトスコープに書き込む。
注意: Claude Code にはネイティブの
/mcpコマンドが別途存在するが、それとは別物。 ネイティブ/mcp addはsettings.json以外のファイル(~/.claude/mcp.json等)に書き込む可能性があるが、 正確な書き込み先は Claude Code のバージョン依存であり未確認(要確認)。 C3 プロジェクトでは必ずこの/mcp-configスキルを使うこと(設定の分散を防ぐため)。
Step 1: 操作を選択する
AskUserQuestion ツール:
{
"questions": [{
"question": "MCP サーバーに対して何をしますか?",
"header": "操作選択",
"options": [
{ "label": "追加する", "description": "新しい MCP サーバーを登録する" },
{ "label": "一覧を見る", "description": "登録済みの MCP サーバーを確認する" },
{ "label": "削除する", "description": "登録済みの MCP サーバーを削除する" }
]
}]
}
Step 2(一覧表示)
.claude/settings.json を Read して mcpServers の内容を整形して表示する。
mcpServersが存在しない・空の場合: 「登録済みの MCP サーバーはありません」と表示して終了する。- 存在する場合: サーバー名・接続方法・URL/コマンドを一覧形式で表示して終了する。
Step 2(削除)
.claude/settings.json を Read して mcpServers の一覧を表示する。
登録がない場合: 「登録済みの MCP サーバーはありません」と表示して終了する。
AskUserQuestion ツール:
{
"questions": [{
"question": "削除するサーバー名を入力してください"
}]
}
入力されたサーバー名のエントリを settings.json から Edit ツールで削除する。
削除後: 「{name} を削除しました」と表示して終了する。
Step 2(追加): 公開 or 社内を選ぶ
AskUserQuestion ツール:
{
"questions": [{
"question": "追加する MCP サーバーの種別を選んでください",
"header": "サーバー種別",
"options": [
{ "label": "公開サーバー", "description": "npm / GitHub 等で公開されているもの(例: @modelcontextprotocol/server-slack)" },
{ "label": "社内・カスタムサーバー", "description": "社内に建てられているもの・自作のもの" }
]
}]
}

Step 3a: キーワードを入力させる
AskUserQuestion ツール:
{
"questions": [{
"question": "探したい MCP サーバーのキーワードや用途を入力してください(例: Slack, GitHub, Postgres)"
}]
}
Step 4a: WebSearch で候補を調査する
WebSearch で以下のクエリで検索する:
MCP server {キーワード} model context protocol site:github.com OR site:npmjs.com OR site:mcp.so
検索結果から候補を最大 4 件抽出する。各候補につき以下を収集する:
- サーバー名(わかりやすい表示名)
- npm パッケージ名またはリポジトリ URL
- 概要(1行)
- 必要な env vars(判明している範囲で)
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.

mcp-config is a skill published in the GitHub repository satoh-y-0323/claude-code-conductor (1 stars, last pushed yesterday), licensed MIT. It adds 28 tokens to every session and 2,665 once invoked, about $0.0001 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 2026-09-04.
