+### Notes
+
+- Users upgrading from v3.1.0 or earlier should first upgrade to v3.2.x for one-time migration
+- Skills and Prompts management are new features requiring no migration
+- Gemini CLI support requires Gemini CLI to be installed separately
+- MCP v3.7.0 unified structure is backward compatible with previous configs

+## Strategic Positioning
+
+### From Tool to Platform
+
+v3.7.0 represents a shift in CC Switch's positioning:
+
+| Aspect            | v3.6                     | v3.7.0                       |
+| ----------------- | ------------------------ | ---------------------------- |
+| **Identity**      | Provider Switcher        | AI CLI Management Platform   |
+| **Scope**         | Configuration Management | Ecosystem Management         |
+| **Applications**  | Claude + Codex           | Claude + Codex + Gemini      |
+| **Capabilities**  | Switch configs           | Extend capabilities (Skills) |
+| **Customization** | Manual editing           | Visual management (Prompts)  |
+| **Integration**   | Isolated apps            | Unified management (MCP)     |
+
+### Six Pillars of AI CLI Management
+
+1. **Configuration Management** - Provider switching and management
+2. **Capability Extension** - Skills installation and lifecycle
+3. **Behavior Customization** - System prompt presets
+4. **Ecosystem Integration** - Deep links and sharing
+5. **Multi-AI Support** - Claude/Codex/Gemini
+6. **Intelligent Detection** - Conflict prevention

+## Strategic Positioning
+
+### From Tool to Platform
+
+v3.7.0 represents a shift in CC Switch's positioning:
+
+| Aspect            | v3.6                     | v3.7.0                       |
+| ----------------- | ------------------------ | ---------------------------- |
+| **Identity**      | Provider Switcher        | AI CLI Management Platform   |
+| **Scope**         | Configuration Management | Ecosystem Management         |
+| **Applications**  | Claude + Codex           | Claude + Codex + Gemini      |
+| **Capabilities**  | Switch configs           | Extend capabilities (Skills) |
+| **Customization** | Manual editing           | Visual management (Prompts)  |
+| **Integration**   | Isolated apps            | Unified management (MCP)     |
+
+### Six Pillars of AI CLI Management
+
+1. **Configuration Management** - Provider switching and management
+2. **Capability Extension** - Skills installation and lifecycle
+3. **Behavior Customization** - System prompt presets
+4. **Ecosystem Integration** - Deep links and sharing
+5. **Multi-AI Support** - Claude/Codex/Gemini
+6. **Intelligent Detection** - Conflict prevention

+# v3.7.0 统一 MCP 管理重构计划
+
+## 📋 项目概述
+
+**目标**：将原有的按应用分离的 MCP 管理（Claude/Codex/Gemini 各自独立管理）重构为统一管理面板，每个 MCP 服务器通过多选框控制应用到哪些客户端。
+
+**版本**：v3.6.2 → v3.7.0
+
+**开始时间**：2025-11-14
+

+        }
+      }
+```
+
+---
+
+## 📐 技术架构
+
+### 数据结构设计
+
+#### 新增：McpApps（应用启用状态）
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize, Default, PartialEq)]
+pub struct McpApps {
+    pub claude: bool,
+    pub codex: bool,
+    pub gemini: bool,
+}
+```
+
+#### 更新：McpServer（统一服务器定义）
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct McpServer {
+    pub id: String,
+    pub name: String,
+    pub server: serde_json::Value,  // 连接配置（stdio/http）
+    pub apps: McpApps,               // 新增：标记应用到哪些客户端
+    pub description: Option<String>,
+    pub homepage: Option<String>,
+    pub docs: Option<String>,
+    pub tags: Vec<String>,
+}
+```
+
+#### 更新：McpRoot（新旧结构并存）
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize, Default)]
+pub struct McpRoot {
+    // v3.7.0 新结构
+    #[serde(skip_serializing_if = "Option::is_none")]
+    pub servers: Option<HashMap<String, McpServer>>,
+
+    // v3.6.x 旧结构（保留用于迁移）
+    #[serde(default, skip_serializing_if = "McpConfig::is_empty")]
+    pub claude: McpConfig,
+    #[serde(default, skip_serializing_if = "McpConfig::is_empty")]
+    pub codex: McpConfig,
+    #[serde(default, skip_serializing_if = "McpConfig::is_empty")]
+    pub gemini: McpConfig,
+}
+```
+
+### 迁移策略
+
+```
+旧配置 (v3.6.x)                    新配置 (v3.7.0)
+─────────────────                  ─────────────────
+mcp:                              mcp:
+  claude:                           servers:
+    servers:                          mcp-fetch:
+      mcp-fetch: {...}      →           id: "mcp-fetch"
+  codex:                                server: {...}
+    servers:                            apps:
+      mcp-filesystem: {...}               claude: true
+                                          codex: true
+                                          gemini: false
+```
+
+**迁移逻辑**：
+1. 检测 `mcp.servers` 是否存在
+2. 若不存在，从 `mcp.claude/codex/gemini.servers` 收集所有服务器
+3. 合并同 id 服务器的 apps 字段
+4. 清空旧结构字段
+5. 保存配置（自动触发）
+
+---
+
+## ✅ 开发进度
+
+### Phase 1: 后端数据结构与迁移 ✅ 已完成
+
+#### 1.1 修改数据结构（app_config.rs）✅

+- ✅ 更新 `McpRoot` 支持新旧结构（lines 81-96）
+- ✅ 添加辅助方法：`is_enabled_for`, `set_enabled_for`, `enabled_apps`
+
+**提交**：`c7b235b` - "feat(mcp): implement unified MCP management for v3.7.0"
+
+#### 1.2 实现迁移逻辑 ✅
+
+**文件**：`src-tauri/src/app_config.rs`

+  - 清空旧结构
+- ✅ 集成到 `MultiAppConfig::load()` 方法（lines 252-257）
+  - 自动检测并执行迁移
+  - 迁移后保存配置
+
+**提交**：`c7b235b` - "feat(mcp): implement unified MCP management for v3.7.0"
+
+---
+
+### Phase 2: 后端服务层重构 ✅ 已完成
+
+#### 2.1 重写 McpService ✅

+- ✅ `sync_enabled()` - 同步特定应用（lines 225-236）
+- ✅ `import_from_claude/codex/gemini()` - 导入包装（lines 239-266）
+
+**提交**：`c7b235b` - "feat(mcp): implement unified MCP management for v3.7.0"
+
+#### 2.2 新增同步函数（mcp.rs）✅
+
+**文件**：`src-tauri/src/mcp.rs`
+
+**新增函数**（lines 800-965）：

+## 🔄 迁移流程
+
+### 用户体验
+
+```
+1. 用户升级到 v3.7.0
+   ↓
+2. 首次启动应用
+   ↓
+3. 后端自动执行迁移
+   - 检测旧结构 (mcp.claude/codex/gemini.servers)
+   - 合并到统一结构 (mcp.servers)
+   - 保存迁移后的配置
+   - 日志记录迁移详情
+   ↓
+4. 前端加载新面板
+   - 显示所有服务器
+   - 三个复选框显示各应用启用状态
+   ↓
+5. 用户无缝使用
+```
+
+### 数据完整性保证
+
+1. **迁移前验证**：
+   - ✅ 校验旧结构合法性
+   - ✅ 记录迁移前状态
+
+2. **迁移中处理**：
+   - ✅ 合并同 id 服务器的 apps 字段
+   - ✅ 处理 id 冲突（保留第一个，记录警告）
+   - ✅ 保留所有元信息（描述、标签、链接）
+
+3. **迁移后清理**：
+   - ✅ 清空旧结构（claude/codex/gemini）
+   - ✅ 自动保存新配置
+   - ✅ 日志记录迁移完成
+
+4. **回滚机制**：
+   - 配置文件有备份（`config.v1.backup.<timestamp>.json`）
+   - 迁移失败时可手动回滚
