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 | $0.01925 | $0.01925 |
| Opus 5.5 | $0.00770 | $0.00770 |
| Sonnet 5.5 | $0.00385 | $0.00385 |
| Haiku 4.5 | $0.00193 | $0.00193 |
Grade A, and why
discord-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 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.
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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.

プロジェクト概要
Discord APIとの統合機能を提供するMCP (Model Context Protocol) サーバーの実装です。MCPプロトコルを通じてClaude DesktopなどのAIクライアントがDiscord APIを安全に利用できるようにします。
技術スタック
- 言語: TypeScript
- フレームワーク: MCP SDK (@modelcontextprotocol/sdk)
- バリデーション: Zod
- コンテナ: Docker
- 実行環境: Node.js 22+
- テストフレームワーク: Vitest
- 主要ライブラリ: MCP SDK, axios (HTTP クライアント)
アーキテクチャ
設計方針
MCPプロトコル準拠: Model Context Protocolの仕様に完全準拠し、標準的なMCPクライアントとの互換性を保つ ドメイン分離: Discord API機能、MCPサーバーコア、ツール実装を明確に分離 型安全性: TypeScriptとZodを活用した厳密な型チェック セキュリティファースト: Discord Bot トークンの安全な管理と適切な権限制御

ツール管理アーキテクチャ
ツールレジストリパターン: 各ツールファイルにMCP定義を含め、registry.tsで一元管理
動的ツール登録: index.tsはレジストリから動的にツール一覧を取得
共通ハンドラー: ToolHandlerクラスがDiscordクライアント初期化とエラーハンドリングを統一
開発ガイドライン
コーディング規約
- ファイル命名: kebab-case (例: discord-client.ts)
- クラス命名: PascalCase (例: DiscordMCPServer)
- 関数・変数命名: camelCase (例: setupToolHandlers)
- 定数命名: UPPER_SNAKE_CASE (例: DEFAULT_TIMEOUT)
- 型命名: PascalCase with suffix (例: DiscordMessageType)
開発フロー
- Git フロー: GitHub Flow (main ブランチからfeatureブランチを作成)
- レビュープロセス: Pull Request必須、1名以上のレビュー
- テスト戦略: ユニットテスト + 統合テスト (Jest使用予定)
- ツール追加時: 新しいMCPツールを追加した場合は、必ずTOOLLIST.md(日本語版・英語版)を更新
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.

discord-mcp CLAUDE.md is an instructions file published in the GitHub repository yone-k/discord-mcp (0 stars, last pushed 1y ago), licensed MIT. It adds 1,925 tokens to every session, about $0.0077 per session on Opus 5.5. 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.
