 ## Development Status

 Currently implemented:
- Basic static site generation
- Markdown parsing and HTML generation
- Template system
- Development server
+- ✅ Project structure and Cargo.toml setup
+- ✅ Basic command-line interface (init, new, build, serve, clean)
+- ✅ Configuration system with TOML support
+- ✅ Markdown parsing with frontmatter support
+- ✅ Template system with Handlebars
+- ✅ Static site generation with posts and pages
+- ✅ Development server with hot reload
+- ✅ AI integration foundation (GPT client, translator, comment system)
+- ✅ atproto client with OAuth support
+- ✅ MCP server integration for AI tools
+- ✅ Test blog with sample content and styling
+
+Planned features:
+- AI-powered content enhancement and suggestions

+# ai.log MCP Integration Guide
+
+ai.logをai.gptと連携するためのMCPサーバー設定ガイド
+
+## MCPサーバー起動
+
+```bash
+# ai.logプロジェクトディレクトリで
+./target/debug/ailog mcp --port 8002
+
+# またはサブディレクトリから
+./target/debug/ailog mcp --port 8002 --path /path/to/blog
+```
+
+## ai.gptでの設定
+
+ai.gptの設定ファイル `~/.config/syui/ai/gpt/config.json` に以下を追加：
+
+```json
+{
+  "mcp": {
+    "enabled": true,
+    "servers": {
+      "ai_gpt": {"base_url": "http://localhost:8001"},
+      "ai_card": {"base_url": "http://localhost:8000"},
+      "ai_log": {"base_url": "http://localhost:8002"}
+    }
+  }
+}
+```
+
+## 利用可能なMCPツール
+
+### 1. create_blog_post
+新しいブログ記事を作成します。
+
+**パラメータ**:
+- `title` (必須): 記事のタイトル
+- `content` (必須): Markdown形式の記事内容
+- `tags` (オプション): 記事のタグ配列
+- `slug` (オプション): カスタムURL slug
+
+**使用例**:
+```python
+# ai.gptからの呼び出し例
+result = await mcp_client.call_tool("create_blog_post", {
+    "title": "AI統合の新しい可能性",
+    "content": "# 概要\n\nai.gptとai.logの連携により...",
+    "tags": ["AI", "技術", "ブログ"]
+})
+```
+
+### 2. list_blog_posts
+既存のブログ記事一覧を取得します。
+
+**パラメータ**:
+- `limit` (オプション): 取得件数上限 (デフォルト: 10)
+- `offset` (オプション): スキップ件数 (デフォルト: 0)
+
+### 3. build_blog
+ブログをビルドして静的ファイルを生成します。
+
+**パラメータ**:
+- `enable_ai` (オプション): AI機能を有効化
+- `translate` (オプション): 自動翻訳を有効化
+
+### 4. get_post_content
+指定したスラッグの記事内容を取得します。
+
+**パラメータ**:
+- `slug` (必須): 記事のスラッグ
+
+## ai.gptからの連携パターン
+
+### 記事の自動投稿
+```python
+# 記憶システムから関連情報を取得
+memories = get_contextual_memories("ブログ")
+
+# AI記事生成
+content = generate_blog_content(memories)
+
+# ai.logに投稿
+result = await mcp_client.call_tool("create_blog_post", {
+    "title": "今日の思考メモ",
+    "content": content,
+    "tags": ["日記", "AI"]
+})
+
+# ビルド実行
+await mcp_client.call_tool("build_blog", {"enable_ai": True})
+```
+
+### 記事一覧の確認と編集
+```python
+# 記事一覧取得
+posts = await mcp_client.call_tool("list_blog_posts", {"limit": 5})
+
+# 特定記事の内容取得
+content = await mcp_client.call_tool("get_post_content", {
+    "slug": "ai-integration"
+})
+
+# 修正版を投稿（上書き）
+updated_content = enhance_content(content)
+await mcp_client.call_tool("create_blog_post", {
+    "title": "AI統合の新しい可能性（改訂版）",
+    "content": updated_content,
+    "slug": "ai-integration-revised"
+})
+```
+
+## 自動化ワークフロー
+
+ai.gptのスケジューラーと組み合わせて：
+
+1. **日次ブログ投稿**: 蓄積された記憶から記事を自動生成・投稿
+2. **記事修正**: 既存記事の内容を自動改善
+3. **関連記事提案**: 過去記事との関連性に基づく新記事提案
+4. **多言語対応**: 自動翻訳によるグローバル展開
+
+## エラーハンドリング
+
+MCPツール呼び出し時のエラーは以下の形式で返されます：
+
+```json
+{
+  "jsonrpc": "2.0",
+  "id": "request_id",
+  "error": {
+    "code": -32000,
+    "message": "エラーメッセージ",
+    "data": null
+  }
+}
+```
+
+## セキュリティ考慮事項
+
+- MCPサーバーはローカルホストでのみ動作
+- ai.gptからの認証済みリクエストのみ処理
+- ファイルアクセスは指定されたブログディレクトリ内に制限

+
+# AI統合ブログシステムの紹介
+
+ai.logは、静的ブログジェネレーターにAI機能を統合した革新的なシステムです。このシステムは存在子理論に基づき、現実の個人の唯一性をデジタル世界で担保することを目指しています。
+
+## 主な機能
+
+### 1. AI記事編集・強化
+- 文法エラーの自動修正
+- 読みやすさの向上
+- 関連情報の追加提案
+
+### 2. 自動翻訳機能
+日本語で書かれた記事を自動的に英語に翻訳し、グローバルな読者にリーチできます。Markdownフォーマットを保持したまま、自然な翻訳を提供します。
+
+### 3. AIコメントシステム
+AI（存在子）が各記事に対して独自の視点からコメントを追加します。これにより、読者に新たな洞察を提供します。
+
+### 4. atproto統合
+分散型SNSプロトコルであるatprotoと統合し、以下を実現します：
+- OAuth認証によるセキュアなログイン
+- コメントデータの分散管理
+- ユーザーデータ主権の確立
+
+## 技術スタック
+
+- **言語**: Rust
+- **AI**: OpenAI GPT API
+- **認証**: atproto OAuth 2.0
+- **デプロイ**: GitHub Actions + Cloudflare Pages
+
+## 今後の展望
+
+ai.logは、単なるブログツールを超えて、AIと人間が共創する新しいコンテンツプラットフォームを目指しています。存在子理論に基づく唯一性の担保により、デジタル世界での個人のアイデンティティを守りながら、AIによる創造性の拡張を実現します。

+        <h1>AI統合ブログシステムの紹介</h1>
+<p>ai.logは、静的ブログジェネレーターにAI機能を統合した革新的なシステムです。このシステムは存在子理論に基づき、現実の個人の唯一性をデジタル世界で担保することを目指しています。</p>
+<h2>主な機能</h2>
