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 | $0.01022 | $0.01022 |
| Opus 5 | $0.00511 | $0.00511 |
| Sonnet 5 | $0.00204 | $0.00204 |
| Haiku 4.5 | $0.00102 | $0.00102 |
Grade C, and why
strands-mcp-agent CLAUDE.md scanned grade C 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.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

プロジェクト概要
このリポジトリは「Strands MCP エージェント」というWebアプリケーションで、AWS発のOSS「Strands Agents SDK」を使用して構築されています。任意のMCPサーバーを設定し、AWS BedrockのClaudeモデルと対話できるStreamlitベースのインターフェースを提供します。
一般的なコマンド
アプリケーションの実行
# ローカルでStreamlitアプリを起動
streamlit run main.py
# デバッグモードで実行
streamlit run main.py --logger.level=debug
依存関係の管理
# 依存関係のインストール
pip install -r requirements.txt
AWS認証設定
# AWS CLIで認証情報を設定
aws configure
# または環境変数で設定
export AWS_ACCESS_KEY_ID="your-access-key-id"
export AWS_SECRET_ACCESS_KEY="your-secret-access-key"
export AWS_DEFAULT_REGION="us-west-2"
コードアーキテクチャと構造
ファイル構成
main.py- Streamlitアプリケーションのメインファイルrequirements.txt- Python依存関係の定義.github/workflows/claude.yml- Claude Code GitHub Actionの設定
主要なコンポーネント
1. Streamlitアプリケーション (main.py)
-
UI構成:
- メインエリア: 質問入力フィールドと回答表示
- サイドバー: BedrockモデルIDとMCPサーバーの設定
-
主要な関数:
create_mcp_client(): MCPクライアントの作成(uvx/npx対応)create_agent_with_multiple_tools(): 複数ツールを持つエージェントの作成stream_response(): 非同期でレスポンスをストリーミング表示extract_tool_info(): ツール実行情報の抽出extract_text(): チャンクからテキストの抽出
2. 技術スタック
- フレームワーク: Streamlit(Webインターフェース)
- AIエージェント: Strands Agents SDK
- LLMプロバイダー: AWS Bedrock(Claudeモデル)
- MCPプロトコル: stdio_client経由でMCPサーバーと通信
- パッケージマネージャー: uvxまたはnpx(MCPサーバー実行用)
3. セッション管理
st.session_stateを使用してMCPサーバー設定を永続化- 動的にMCPサーバーの追加・削除が可能
4. 認証とシークレット管理
- ローカル開発: AWS環境変数または~/.aws/credentials
- Streamlit Community Cloud: st.secretsを使用
- AWS認証情報
- Langfuseトレース設定(オプション)
重要な注意点
- MCPサーバー接続: stdioプロトコルをサポートする任意のMCPサーバーに接続可能
- 非同期処理: asyncioを使用してストリーミングレスポンスを実装
- エラーハンドリング: MCPサーバー接続エラーやBedrock認証エラーに注意
- デプロイ: Streamlit Community Cloudへのデプロイ時はシークレット設定が必須

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.

strands-mcp-agent CLAUDE.md is an instructions file published in the GitHub repository minorun365/strands-mcp-agent (5 stars, last pushed 1y ago), licensed MIT. It adds 1,022 tokens to every session, about $0.0051 per session on Opus 5. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
