**Claude × GPT-4o 相互コードレビュー MCP サーバー**

2つの LLM がそれぞれ独立にコードをレビューし、Claude が両方の指摘を統合した最終レポートを返す MCP (Model Context Protocol) サーバーです。

## 30秒で読める要約

- Claude Desktop / Claude Code / 任意の MCP クライアントから呼べる
- `review_file` / `review_code` / `review_diff` の 3 ツール
- 拡張子から言語自動推定 (`.py` → python, `.ts` → typescript, ...)
- API キーは環境変数で渡す
- コスト追跡はオプション (`ENABLE_COST_TRACKING=1` で有効化)

## クイックスタート (Claude Code)

```bash
claude mcp add mutual-review -- uvx mutual-review-mcp
```

事前に `ANTHROPIC_API_KEY` と `OPENAI_API_KEY` を環境変数に設定してください。

## インストール

```bash
pip install mutual-review-mcp
# または、インストールせず一時実行:
uvx mutual-review-mcp
```

### 詳細

#### A. uvx (推奨・一時実行)

```bash
uvx mutual-review-mcp              # MCPサーバー起動 (stdio)
uvx --from mutual-review-mcp mutual-review path/to/foo.py  # CLI
```

#### B. pip

```bash
pip install mutual-review-mcp
mutual-review-mcp                  # MCP サーバー起動
mutual-review path/to/foo.py       # 単発 CLI
```

#### C. git clone (開発用)

```bash
git clone https://github.com/miharu8686/mutual-review-mcp
cd mutual-review-mcp
pip install -e .[dev]
pytest
```

## Claude Desktop 設定

`%APPDATA%/Claude/claude_desktop_config.json` (macOS は `~/Library/Application Support/Claude/claude_desktop_config.json`) に:

        "OPENAI_API_KEY": "sk-..."
      }
    }
  }
}
```
