+# CodexLens MCP Integration - Implementation Summary
+
+> Implementation Date: 2026-01-19
+> Project: CCW Dashboard + CodexLens MCP
+
+## 实现概览
+
+成功完成 codex-lens LSP 功能分析及其 MCP 端点设计，并在 CCW view 中实现工具选择功能。
+
+---
+
+## ✅ 已完成任务
+
+### 1. **Gemini 分析 - CodexLens LSP 功能** ✓
+
+**输出文件**：`D:\Claude_dms3\codex-lens\docs\MCP_ENDPOINT_DESIGN.md`
+
+**分析结果**：
+- **4 个核心 MCP 工具**已规划：
+  1. `code.symbol.search` - 符号搜索（对应 `workspace/symbol` 和 `textDocument/completion`）
+  2. `code.symbol.findDefinition` - 查找定义（对应 `textDocument/definition`）
+  3. `code.symbol.findReferences` - 查找引用（对应 `textDocument/references`）
+  4. `code.symbol.getHoverInfo` - 悬停信息（对应 `textDocument/hover`）
+
+**技术细节**：
+- 后端实现基于 `GlobalSymbolIndex` 和 `ChainSearchEngine`
+- 完整的 MCP schema 定义（参数、返回值、使用场景）
+- 命名规范：`code.symbol.<operation>`
+
+---
+
+### 2. **实现 Multi-Select 字段类型** ✓
+
+**修改文件**：`ccw/src/templates/dashboard-js/components/mcp-manager.js`
+
+**核心实现**：
+
+#### 字段渲染（line 1506-1529）
+```javascript
+${field.type === 'multi-select' ? `
+  <div id="wizard-field-${field.key}" class="space-y-2 p-2 bg-muted/30 border border-border rounded-lg max-h-48 overflow-y-auto">
+    ${(field.options || []).map(opt => {
+      const isChecked = (field.default || []).includes(opt.value);
+      return `
+        <label class="flex items-center gap-2 p-2 rounded-md hover:bg-accent cursor-pointer transition-colors">
+          <input type="checkbox"
+                 class="wizard-multi-select-${field.key} rounded border-border text-primary focus:ring-primary"
+                 value="${escapeHtml(opt.value)}"
+                 ${isChecked ? 'checked' : ''}>
+          <span class="text-sm text-foreground">${escapeHtml(opt.label)}</span>
+          ${opt.desc ? `<span class="text-xs text-muted-foreground ml-auto">${escapeHtml(opt.desc)}</span>` : ''}
+        </label>
+      `;
+    }).join('')}
+  </div>
+` : `
+  <input type="${field.type || 'text'}" ...>
+`}
+```
+
+#### 值收集（line 1637-1661）
+```javascript
+if (field.type === 'multi-select') {
+  const checkboxes = document.querySelectorAll(`.wizard-multi-select-${field.key}:checked`);
+  const selectedValues = Array.from(checkboxes).map(cb => cb.value);
+
+  if (field.required && selectedValues.length === 0) {
+    showRefreshToast(`${t(field.labelKey)} - ${t('mcp.wizard.selectAtLeastOne')}`, 'error');
+    hasError = true;
+    break;
+  }
+
+  values[field.key] = selectedValues;
+}
+```
+
+**特性**：
+- ✅ 复选框列表 UI
+- ✅ 默认值预选
+- ✅ 必填验证
+- ✅ 悬停高亮效果
+- ✅ 滚动容器（max-height: 48）
+
+---
+
+### 3. **添加 CodexLens 到推荐 MCP 列表** ✓
+
+**修改位置**：`ccw/src/templates/dashboard-js/components/mcp-manager.js` (line 1430-1457)
+
+**MCP 定义**：
+```javascript
+{
+  id: 'codex-lens-tools',
+  nameKey: 'mcp.codexLens.name',
+  descKey: 'mcp.codexLens.desc',
+  icon: 'code-2',
+  category: 'code-intelligence',
+  fields: [
+    {
+      key: 'tools',
+      labelKey: 'mcp.codexLens.field.tools',
+      type: 'multi-select',  // 使用新的 multi-select 类型
+      options: [
+        { value: 'symbol.search', label: 'Symbol Search', desc: 'Workspace symbol search' },
+        { value: 'symbol.findDefinition', label: 'Find Definition', desc: 'Go to definition' },
+        { value: 'symbol.findReferences', label: 'Find References', desc: 'Find all references' },
+        { value: 'symbol.getHoverInfo', label: 'Hover Information', desc: 'Rich symbol info' }
+      ],
+      default: ['symbol.search', 'symbol.findDefinition', 'symbol.findReferences'],
+      required: true,
+      descKey: 'mcp.codexLens.field.tools.desc'
+    }
+  ],
+  buildConfig: (values) => {
+    const tools = values.tools || [];
+    const env = { CODEXLENS_ENABLED_TOOLS: tools.join(',') };
+    return buildCrossPlatformMcpConfig('npx', ['-y', 'codex-lens-mcp'], { env });
+  }
+}
+```
+
+**配置生成**：
+```javascript
+// 示例输出
+{
+  command: "cmd",  // Windows 自动包装
+  args: ["/c", "npx", "-y", "codex-lens-mcp"],
+  env: {
+    CODEXLENS_ENABLED_TOOLS: "symbol.search,symbol.findDefinition,symbol.findReferences"
+  }
+}
+```
+
+---
+
+### 4. **添加 i18n 翻译支持** ✓
+
+**修改文件**：`ccw/src/templates/dashboard-js/i18n.js`
+
+#### 英文翻译（line 959-963）
+```javascript
+'mcp.codexLens.name': 'CodexLens Tools',
+'mcp.codexLens.desc': 'Code intelligence tools for symbol search, navigation, and reference finding',
+'mcp.codexLens.field.tools': 'Enabled Tools',
+'mcp.codexLens.field.tools.desc': 'Select the code intelligence tools to enable for this MCP server',
+'mcp.wizard.selectAtLeastOne': 'Please select at least one option',
+```
+
+#### 中文翻译（line 3286-3290）
+```javascript
+'mcp.codexLens.name': 'CodexLens 工具',
+'mcp.codexLens.desc': '代码智能工具，提供符号搜索、代码导航和引用查找功能',
+'mcp.codexLens.field.tools': '启用的工具',
+'mcp.codexLens.field.tools.desc': '选择要启用的代码智能工具',

-## 🔧 技术变更
+## 📋 Implementation Architecture

-### 1. HybridSearchEngine 修改
+### Three Integration Paths

-**文件**: `codexlens/search/hybrid_search.py`
+```
+Path 1: VSCode Bridge (✅ Implemented)
+─────────────────────────────────────
+Claude Code → vscode_lsp MCP tool → HTTP → ccw-vscode-bridge → VSCode API → Language Servers

-**变更内容**:
-```python
-def search(
-    self,
-    index_path: Path,
-    query: str,
-    limit: int = 20,
-    enable_fuzzy: bool = True,
-    enable_vector: bool = False,
-    pure_vector: bool = False,  # ← 新增参数
-) -> List[SearchResult]:
-    """...
-    Args:
-        ...
-        pure_vector: If True, only use vector search without FTS fallback
-    """
-    backends = {}
+Path 2: Standalone LSP Server (📝 Planned)
+──────────────────────────────────────────
+Any LSP Client → codexlens-lsp → Language Server Multiplexer → Language Servers

-    if pure_vector:
-        # 纯向量模式：只使用向量搜索
-        if enable_vector:
-            backends["vector"] = True
-        else:
-            # 无效配置警告
-            self.logger.warning(...)
-            backends["exact"] = True
-    else:
-        # 混合模式：总是包含exact作为基线
-        backends["exact"] = True
-        if enable_fuzzy:
-            backends["fuzzy"] = True
-        if enable_vector:
-            backends["vector"] = True
+Path 3: Index-Based (✅ Existing)
+─────────────────────────────────
+Claude Code → codex_lens_lsp → Python API → SQLite Index → Cached Results
 ```

-**影响**:
- ✓ 向后兼容：`vector`模式行为不变（vector + exact）
- ✓ 新功能：`pure_vector=True`时仅使用向量搜索
- ✓ 错误处理：无效配置时降级到exact搜索
+### Smart Routing Strategy

-### 2. ChainSearchEngine 修改
-
-**文件**: `codexlens/search/chain_search.py`
-
-**变更内容**:
-```python
-@dataclass
-class SearchOptions:
-    """...
-    Attributes:
-        ...
-        pure_vector: If True, only use vector search without FTS fallback
-    """
-    ...
-    pure_vector: bool = False  # ← 新增字段
-
-def _search_single_index(
-    self,
-    ...
-    pure_vector: bool = False,  # ← 新增参数
-    ...
-):
-    """...
-    Args:
-        ...
-        pure_vector: If True, only use vector search without FTS fallback
-    """
-    if hybrid_mode:
-        hybrid_engine = HybridSearchEngine(weights=hybrid_weights)
-        fts_results = hybrid_engine.search(
-            ...
-            pure_vector=pure_vector,  # ← 传递参数
-        )
+```javascript
+// Priority: VSCode Bridge → Standalone LSP → Index-based
+if (vscodeBridgeAvailable) {
+  return useVSCodeBridge();
+} else if (standaloneLSPAvailable) {
+  return useStandaloneLSP();
+} else {
+  return useIndexBased();
+}
 ```

-**影响**:
- ✓ `SearchOptions`支持`pure_vector`配置
- ✓ 参数正确传递到底层`HybridSearchEngine`
- ✓ 多索引搜索时每个索引使用相同配置
-
-### 3. CLI 命令修改
-
-**文件**: `codexlens/cli/commands.py`
-
-**变更内容**:
-```python
-@app.command()
-def search(
-    ...
-    mode: str = typer.Option(
-        "exact",
-        "--mode",
-        "-m",
-        help="Search mode: exact, fuzzy, hybrid, vector, pure-vector."  # ← 更新帮助
-    ),
-    ...
-):
-    """...
-    Search Modes:
-      - exact: Exact FTS using unicode61 tokenizer (default)
-      - fuzzy: Fuzzy FTS using trigram tokenizer
-      - hybrid: RRF fusion of exact + fuzzy + vector (recommended)
-      - vector: Vector search with exact FTS fallback
-      - pure-vector: Pure semantic vector search only  # ← 新增模式
-
-    Vector Search Requirements:
-      Vector search modes require pre-generated embeddings.
-      Use 'codexlens-embeddings generate' to create embeddings first.
-    """
-
-    valid_modes = ["exact", "fuzzy", "hybrid", "vector", "pure-vector"]  # ← 更新
-
-    # Map mode to options
-    ...
-    elif mode == "pure-vector":
-        hybrid_mode, enable_fuzzy, enable_vector, pure_vector = True, False, True, True  # ← 新增
-    ...
-
-    options = SearchOptions(
-        ...
-        pure_vector=pure_vector,  # ← 传递参数
-    )
-```
-
-**影响**:
- ✓ CLI支持5种搜索模式
- ✓ 帮助文档清晰说明各模式差异
- ✓ 参数正确映射到`SearchOptions`
-

+# VSCode Bridge
+cd ccw-vscode-bridge
+npm install
+npm run compile

-tests/test_pure_vector_search.py::TestPureVectorSearch
-  ✓ test_pure_vector_without_embeddings        PASSED
-  ✓ test_vector_with_fallback                  PASSED
-  ✓ test_pure_vector_invalid_config            PASSED

+# CCW MCP (already setup)
+cd ccw
+npm install

-tests/test_pure_vector_search.py::TestSearchModeComparison
-  ✓ test_mode_comparison_without_embeddings    PASSED
-
-======================== 5 passed in 0.64s =========================
-```
-
-### 模式对比测试结果
-
-```
-Mode comparison (without embeddings):
-  exact: 1 results        ← FTS精确匹配
-  fuzzy: 1 results        ← FTS模糊匹配
-  vector: 1 results       ← Vector模式回退到exact
-  pure_vector: 0 results  ← Pure vector无嵌入时返回空 ✓ 预期行为
-```
-
-**关键验证**:
- ✅ 纯向量模式在无嵌入时正确返回空列表
- ✅ Vector模式保持向后兼容（有FTS后备）
- ✅ 所有模式参数映射正确
-

-
-## 📊 性能影响
-
-### 搜索延迟对比
-
-基于测试数据（100文件，~500代码块，无嵌入）：
-
-| 模式 | 延迟 | 变化 |
-|------|------|------|
-| exact | 5.6ms | - (基线) |
-| fuzzy | 7.7ms | +37% |
-| vector (with fallback) | 7.4ms | +32% |
-| **pure-vector (no embeddings)** | **2.1ms** | **-62%** ← 快速返回空 |
-| hybrid | 9.0ms | +61% |
-
-**分析**:
- ✓ Pure-vector模式在无嵌入时快速返回（仅检查表存在性）
- ✓ 有嵌入时，pure-vector与vector性能相近（~7ms）
- ✓ 无额外性能开销

-## 🔄 向后兼容性
+## 💡 Key Design Decisions

-### 保持兼容的设计决策
+### 1. Why Three Integration Paths?

-1. **默认值保持不变**
-   ```python
-   def search(..., pure_vector: bool = False):
-       # 默认 False，保持现有行为
+- **VSCode Bridge**: Easiest setup, leverages VSCode's built-in language servers
+- **Standalone LSP**: IDE-agnostic, works with any LSP client
+- **Index-based**: Fallback for offline or cached queries
+
+### 2. Why HTTP for VSCode Bridge?
+
+- ✅ Simplest cross-process communication
+- ✅ No complex IPC/socket management
+- ✅ Easy to debug with curl/Postman
+- ✅ CORS support for web-based tools
+
+### 3. Why Port 3457?
+
+- Unique port unlikely to conflict
+- Easy to remember (345-7)
+- Same approach as cclsp (uses stdio)
+
+### 4. Why Not Modify smart_search?
+
+User feedback: 
+> "第一种跟当前的符号搜索没区别哎"  
+> (Method 1 has no difference from current symbol search)
+
+**Solution**: Implement real LSP server that connects to live language servers, not pre-indexed data.
+
+---
+
+## 🚀 Quick Start Guide
+
+### Test VSCode Bridge Now
+
+1. **Install Extension**:
+   ```bash
+   cd ccw-vscode-bridge
+   npm install && npm run compile
+   code --install-extension .
   ```

-2. **Vector模式行为不变**
-   ```python
-   # 之前和之后行为相同
-   codexlens search "query" --mode vector
-   # → 总是返回结果（vector + exact）
+2. **Reload VSCode**:
+   - Press `Cmd+Shift+P` (Mac) or `Ctrl+Shift+P` (Windows)
+   - Type "Reload Window"
+
+3. **Verify Bridge is Running**:
+   ```bash
+   curl http://localhost:3457/get_definition \
+     -X POST \
+     -H "Content-Type: application/json" \
+     -d '{"file_path":"/path/to/file.ts","line":10,"character":5}'
   ```

-3. **新模式是可选的**
-   ```python
-   # 用户可以继续使用现有模式
-   codexlens search "query" --mode exact
-   codexlens search "query" --mode hybrid
-   ```
-
-4. **API签名扩展**
-   ```python
-   # 新参数是可选的，不破坏现有代码
-   engine.search(index_path, query)  # ← 仍然有效
-   engine.search(index_path, query, pure_vector=True)  # ← 新功能
+4. **Test via CCW**:
+   ```javascript
+   // In Claude Code or MCP client
+   await executeTool('vscode_lsp', {
+     action: 'get_definition',
+     file_path: '/absolute/path/to/file.ts',
+     line: 10,
+     character: 5
+   });
   ```

-## 🐛 已知限制
+## 📞 Support & Troubleshooting

-### 当前限制
+### Common Issues

-1. **需要手动生成嵌入**
-   - 不会自动触发嵌入生成
-   - 需要运行独立脚本
+**Issue**: "Could not connect to VSCode Bridge"
+**Solution**: 
+1. Ensure VSCode is running
+2. Check if extension is activated: `Cmd+Shift+P` → "CCW VSCode Bridge"
+3. Verify port 3457 is not in use: `lsof -i :3457`

-2. **无增量更新**
-   - 代码更新后需要完全重新生成嵌入
-   - 未来将支持增量更新
+**Issue**: "No LSP server available"
+**Solution**: Open the file in VSCode workspace first

-3. **向量搜索比FTS慢**
-   - 约7ms vs 5ms（单索引）
-   - 可接受的折衷
-
-### 缓解措施
-
- 文档清楚说明嵌入生成步骤
- 提供批量生成脚本
- 添加`--force`选项快速重新生成
+**Issue**: "File not found"
+**Solution**: Use absolute paths, not relative

+# CodexLens MCP Endpoint Design
+
+> Generated by Gemini Analysis | 2026-01-19
+> Document Version: 1.0
+
+## Overview
+
+This document provides the complete MCP endpoint design for exposing codex-lens LSP capabilities through the Model Context Protocol.
+
+## Related Files
+- `src/codexlens/lsp/server.py` - Main LSP server initialization, component management, and capability declaration.
+- `src/codexlens/lsp/handlers.py` - Implementation of handlers for core LSP requests (definition, references, completion, hover, workspace symbols).
+- `src/codexlens/lsp/providers.py` - Helper classes, specifically `HoverProvider` for generating rich hover information.
+- `src/codexlens/storage/global_index.py` - The backing data store (`GlobalSymbolIndex`) that powers most of the symbol lookups.
+- `src/codexlens/search/__init__.py` - Exposes the `ChainSearchEngine`, used for advanced reference searching.
+
+## Summary
+
+The `codex-lens` LSP implementation exposes five core code navigation and search features: go to definition, find references, code completion, hover information, and workspace symbol search. These features are primarily powered by two components: `GlobalSymbolIndex` for fast, project-wide symbol lookups (used by definition, completion, hover, and workspace symbols) and `ChainSearchEngine` for advanced, relationship-aware reference finding.
+
+The following MCP tool design externalizes these backend capabilities, allowing a client to leverage the same code intelligence features outside of an LSP context.
+
+## MCP Tool Group: `code.symbol`
+
+This group provides tools for searching and retrieving information about code symbols (functions, classes, etc.) within an indexed project.
+
+---
+
+### 1. `code.symbol.search`
+
+**Description**: Searches for symbols across the entire indexed project, supporting prefix or contains matching. Ideal for implementing workspace symbol searches or providing code completion suggestions.
+
+**Mapped LSP Features**: `workspace/symbol`, `textDocument/completion`
+
+**Backend Implementation**: This tool directly maps to the `GlobalSymbolIndex.search` method.
+- Reference: `src/codexlens/lsp/handlers.py:302` (in `lsp_workspace_symbol`)
+- Reference: `src/codexlens/lsp/handlers.py:256` (in `lsp_completion`)
+
+**Schema**:
+```json
+{
+  "name": "code.symbol.search",
+  "description": "Searches for symbols across the entire indexed project, supporting prefix or contains matching. Ideal for implementing workspace symbol searches or providing code completion suggestions.",
+  "inputSchema": {
+    "type": "object",
+    "properties": {
+      "query": {
+        "type": "string",
+        "description": "The symbol name or prefix to search for."
+      },
+      "kind": {
+        "type": "string",
+        "description": "Optional: Filter results to only include symbols of a specific kind (e.g., 'function', 'class', 'method').",
+        "nullable": true
+      },
+      "prefix_mode": {
+        "type": "boolean",
+        "description": "If true, treats the query as a prefix (name LIKE 'query%'). If false, performs a contains search (name LIKE '%query%'). Defaults to true.",
+        "default": true
+      },
+      "limit": {
+        "type": "integer",
+        "description": "The maximum number of symbols to return.",
+        "default": 50
+      }
+    },
+    "required": ["query"]
+  }
+}
+```
+
+**Returns**:
+```typescript
+Array<{
+  name: string;          // The name of the symbol
+  kind: string;          // The kind of the symbol (e.g., 'function', 'class')
+  file_path: string;     // The absolute path to the file containing the symbol
+  range: {
+    start_line: number;  // The 1-based starting line number
+    end_line: number;    // The 1-based ending line number
+  }
+}>
+```
+
+---
+
+### 2. `code.symbol.findDefinition`
+
+**Description**: Finds the definition location(s) for a symbol with an exact name match. This corresponds to a 'Go to Definition' feature.
+
+**Mapped LSP Feature**: `textDocument/definition`
+
+**Backend Implementation**: This tool uses `GlobalSymbolIndex.search` with `prefix_mode=False` and then filters for an exact name match.
+- Reference: `src/codexlens/lsp/handlers.py:180` (in `lsp_definition`)
+
+**Schema**:
+```json
+{
+  "name": "code.symbol.findDefinition",
+  "description": "Finds the definition location(s) for a symbol with an exact name match. This corresponds to a 'Go to Definition' feature.",
+  "inputSchema": {
+    "type": "object",
+    "properties": {
+      "symbol_name": {
+        "type": "string",
+        "description": "The exact name of the symbol to find."
+      },
+      "kind": {
+        "type": "string",
+        "description": "Optional: Disambiguate by providing the symbol kind (e.g., 'function', 'class').",
+        "nullable": true
+      }
+    },
+    "required": ["symbol_name"]
+  }
+}
+```
+
+**Returns**:
+```typescript
+Array<{
+  name: string;          // The name of the symbol
+  kind: string;          // The kind of the symbol
+  file_path: string;     // The absolute path to the file
+  range: {
+    start_line: number;  // The 1-based starting line number
+    end_line: number;    // The 1-based ending line number
+  }
+}>
+```
+
+---
+
+### 3. `code.symbol.findReferences`
+
+**Description**: Finds all references to a symbol throughout the project. Uses advanced relationship analysis for accuracy where possible, falling back to name-based search.
+
+**Mapped LSP Feature**: `textDocument/references`
+
+**Backend Implementation**: This primarily uses `ChainSearchEngine.search_references` for accuracy, which is more powerful than a simple name search.
+- Reference: `src/codexlens/lsp/handlers.py:218` (in `lsp_references`)
+
+**Schema**:
+```json
+{
+  "name": "code.symbol.findReferences",
+  "description": "Finds all references to a symbol throughout the project. Uses advanced relationship analysis for accuracy where possible.",
+  "inputSchema": {
+    "type": "object",
+    "properties": {
+      "symbol_name": {
+        "type": "string",
+        "description": "The name of the symbol to find references for."
+      },
+      "context_path": {
+        "type": "string",
+        "description": "The source path of the current project or workspace root to provide context for the search."
+      },
+      "limit": {
+        "type": "integer",
+        "description": "The maximum number of references to return.",
+        "default": 200
+      }
+    },
+    "required": ["symbol_name", "context_path"]
+  }
+}
+```
+
+**Returns**:
+```typescript
+Array<{
+  file_path: string;    // The absolute path to the file containing the reference
+  line: number;         // The 1-based line number of the reference
+  column: number;       // The 0-based starting column of the reference
+}>
+```
+
+---
+
+### 4. `code.symbol.getHoverInfo`
+
+**Description**: Retrieves rich information for a symbol, including its signature and location, suitable for displaying in a hover card.
+
+**Mapped LSP Feature**: `textDocument/hover`
+
+**Backend Implementation**: This tool encapsulates the logic from `HoverProvider`, which finds a symbol in `GlobalSymbolIndex` and then reads the source file to extract its signature.
+- Reference: `src/codexlens/lsp/handlers.py:285` (instantiates `HoverProvider`)
+- Reference: `src/codexlens/lsp/providers.py:53` (in `HoverProvider.get_hover_info`)
+
+**Schema**:
+```json
+{
+  "name": "code.symbol.getHoverInfo",
+  "description": "Retrieves rich information for a symbol, including its signature and location, suitable for displaying in a hover card.",
+  "inputSchema": {
+    "type": "object",
+    "properties": {
+      "symbol_name": {
+        "type": "string",
+        "description": "The exact name of the symbol to get hover information for."
+      }
+    },
+    "required": ["symbol_name"]
+  }
+}
+```
+
+**Returns**:
+```typescript
+{
+  name: string;           // The name of the symbol
+  kind: string;           // The kind of the symbol
+  signature: string;      // The full code signature as extracted from source
+  file_path: string;      // The absolute path to the file
+  start_line: number;     // The 1-based starting line number
+} | null  // null if symbol not found
+```
+

+
+## Integration with CCW MCP Manager
+
+The `codex-lens-tools` MCP server should be added to the recommended MCP servers list in `ccw/src/templates/dashboard-js/components/mcp-manager.js`:
+
+```javascript
+{
+  id: 'codex-lens-tools',
+  nameKey: 'mcp.codexLens.name',
+  descKey: 'mcp.codexLens.desc',
+  icon: 'search-code',
+  category: 'code-intelligence',
+  fields: [
+    {
+      key: 'toolSelection',
+      labelKey: 'mcp.codexLens.field.tools',
+      type: 'multi-select',
+      options: [
+        { value: 'symbol.search', label: 'Symbol Search' },
+        { value: 'symbol.findDefinition', label: 'Find Definition' },
+        { value: 'symbol.findReferences', label: 'Find References' },
+        { value: 'symbol.getHoverInfo', label: 'Hover Information' }
+      ],
+      default: ['symbol.search', 'symbol.findDefinition', 'symbol.findReferences'],
+      required: true,
+      descKey: 'mcp.codexLens.field.tools.desc'
+    }
+  ],
+  buildConfig: (values) => {
+    const tools = values.toolSelection || [];
+    const env = { CODEXLENS_ENABLED_TOOLS: tools.join(',') };
+    return buildCrossPlatformMcpConfig('npx', ['-y', 'codex-lens-mcp'], { env });
+  }
+}
+```
+
+## Tool Naming Convention
+
+- **Namespace**: `code.*` for code intelligence tools
+- **Category**: `symbol` for symbol-related operations
+- **Operation**: Descriptive verb (search, findDefinition, findReferences, getHoverInfo)
+- **Full Pattern**: `code.symbol.<operation>`
+
+This naming scheme aligns with MCP conventions and is easily extensible for future categories (e.g., `code.types.*`, `code.imports.*`).
+
+## Future Enhancements
+
+1. **Document Symbol Tool** (`code.symbol.getDocumentSymbols`)
+   - Maps LSP `textDocument/documentSymbol`
+   - Returns all symbols in a specific file
+
+2. **Type Information** (`code.type.*` group)
+   - Type definitions and relationships
+   - Generic resolution
+
+3. **Relationship Analysis** (`code.relation.*` group)
+   - Call hierarchy
+   - Inheritance chains
+   - Import dependencies

+# CodexLens Real LSP Server Implementation Plan
+
+> **Version**: 2.0  
+> **Status**: Ready for Implementation  
+> **Based on**: Existing LSP_INTEGRATION_PLAN.md + Real Language Server Integration  
+> **Goal**: Implement true LSP server functionality (like cclsp), not pre-indexed search
+
+---
+
+## Executive Summary
+
+### Current State vs Target State
+
+| Aspect | Current (Pre-indexed) | Target (Real LSP) |
+|--------|----------------------|-------------------|
+| **Data Source** | Cached database index | Live language servers |
+| **Freshness** | Stale (depends on re-index) | Real-time (LSP protocol) |
+| **Accuracy** | Good for indexed content | Perfect (from language server) |
+| **Latency** | <50ms (database) | ~50-200ms (LSP) |
+| **Language Support** | Limited to parsed symbols | Full LSP support (all languages) |
+| **Complexity** | Simple (DB queries) | High (LSP protocol + server mgmt) |
+
+### Why Real LSP vs Index-Based
+
+**Problem with current approach**:
+- 符号搜索与smart_search没有本质区别
+- 依赖预索引数据，不能实时反映代码变化
+- 不支持advanced LSP功能(rename, code actions等)
+
+**Advantages of real LSP**:
+- ✅ Real-time code intelligence
+- ✅ Supported by all major IDEs (VSCode, Neovim, Sublime, etc.)
+- ✅ Standard protocol (Language Server Protocol)
+- ✅ Advanced features: rename, code actions, formatting
+- ✅ Language-agnostic (TypeScript, Python, Go, Rust, Java, etc.)

+
+### Key Differences from Index-Based Approach
+
+1. **Request Flow**
+   - Index: Query → Database → Results
+   - LSP: Request → Route to LS → LS processes live code → Results
+
+2. **Configuration**
+   - Index: Depends on indexing state
+   - LSP: Depends on installed language servers
+
+3. **Latency Profile**
+   - Index: Consistent (~50ms)
+   - LSP: Variable (50-500ms depending on LS performance)
+
+---
+
+## Implementation Phases
+
+### Phase 1: LSP Server Bridge (Foundation)
+
+**Duration**: ~3-5 days

+- [ ] Reuses existing server instances
+- [ ] Handles server restarts on crash
+- [ ] Respects initialization options from config
+
+---
+
+### Phase 3: Core LSP Handlers
+
+**Duration**: ~5-7 days  
+**Complexity**: Medium  
+**Dependencies**: Phase 1-2 complete
+
+#### 3.1 Essential Handlers
+
+Implement LSP request handlers for core functionality:
+
+**Handler Mapping**:

+}
+```
+
+#### 3.2 Request Forwarding Logic
+
+```python
+def forward_request_to_lsp(handler_name, params):
+    """Forward request to appropriate language server."""
+    
+    # Extract document info
+    document_uri = params.get("textDocument", {}).get("uri")
+    file_ext = extract_extension(document_uri)
+    
+    # Get language server
+    ls = multiplexer.get_server(file_ext)
+    if not ls:
+        return {"error": f"No LS for {file_ext}"}
+    
+    # Convert position (1-based → 0-based)
+    normalized_params = normalize_positions(params)
+    
+    # Forward to LS
+    response = ls.send_request(handler_name, normalized_params)
+    
+    # Convert response format
+    return normalize_response(response)
+```
+
+#### 3.3 Acceptance Criteria
+
+- [ ] All handlers implemented and tested
+- [ ] Proper position coordinate conversion (LSP is 0-based, user-facing is 1-based)
+- [ ] Error handling for missing language servers
+- [ ] Response formatting matches LSP spec
+- [ ] Latency < 500ms for 95th percentile
+
+---
+
+### Phase 4: Advanced Features
+
+**Duration**: ~3-5 days  
+**Complexity**: Medium  
+**Dependencies**: Phase 1-3 complete
+
+#### 4.1 Position Tolerance (cclsp-like feature)
+
+Some LSP clients (like Claude Code with fuzzy positions) may send imprecise positions. Implement retry logic:
+
+```python
+def find_symbol_with_tolerance(ls, uri, position, max_attempts=5):
+    """Try multiple position offsets if exact position fails."""
+    
+    positions_to_try = [
+        position,                              # Original
+        (position.line - 1, position.char),   # One line up
+        (position.line + 1, position.char),   # One line down
+        (position.line, max(0, position.char - 1)),  # One char left
+        (position.line, position.char + 1),   # One char right
+    ]
+    
+    for pos in positions_to_try:
+        try:
+            result = ls.send_request("textDocument/definition", {
+                "textDocument": {"uri": uri},
+                "position": pos
+            })
+            if result:
+                return result
+        except:
+            continue
+    
+    return None
+```
+
+#### 4.2 MCP Integration (Optional)
+
+Extend with MCP provider for Claude Code hooks:
+
+```python
+class MCPBridgeHandler:
+    """Bridge LSP results into MCP context."""
+    
+    def build_mcp_context_from_lsp(self, symbol_name, lsp_results):
+        """Convert LSP responses to MCP context."""
+        # Implementation
+        pass
+```
+
+#### 4.3 Acceptance Criteria
+
+- [ ] Position tolerance working (≥3 positions tried)
+- [ ] MCP context generation functional
+- [ ] Hook system integration complete
+- [ ] All test coverage > 80%
+
+---
+
+### Phase 5: Deployment & Documentation
+
+**Duration**: ~2-3 days  
+**Complexity**: Low  
+**Dependencies**: Phase 1-4 complete
+
+#### 5.1 Installation & Setup Guide
+
+Create comprehensive documentation:
+- Installation instructions for each supported language
+- Configuration guide
+- Troubleshooting
+- Performance tuning
+
+#### 5.2 CLI Tools
+
+```bash
+# Start LSP server
+codexlens-lsp --stdio
+
+# Check configured language servers
+codexlens-lsp --list-servers
+
+# Validate configuration
+codexlens-lsp --validate-config
+
+# Show logs
+codexlens-lsp --log-level debug
+```
+
+#### 5.3 Acceptance Criteria
+
+- [ ] Documentation complete with examples
+- [ ] All CLI commands working
+- [ ] Integration tested with VS Code, Neovim
+- [ ] Performance benchmarks documented

+- ✅ Follows industry standard protocol
+
+**Cons**:
+- ❌ More complex implementation
+- ❌ Depends on external language servers
+- ❌ Higher latency than index-based
+
+**Effort**: ~20-25 days
+
+---
+
+### Option B: Enhanced Index-Based (Current Approach)
+**Pros**:
+- ✅ Simple implementation
+- ✅ Fast (<50ms)
+- ✅ No external dependencies
+
+**Cons**:
+- ❌ Same as smart_search (user's concern)
+- ❌ Stale data between re-indexes
+- ❌ Limited to indexed symbols
+- ❌ No advanced LSP features
+
+**Effort**: ~5-10 days
+
+---
+
+### Option C: Hybrid (LSP + Index)
+**Pros**:

+- ✅ Fallback to index
+- ✅ Best of both worlds
+
+**Cons**:
+- ❌ Highest complexity
+- ❌ Difficult to debug conflicts
+- ❌ Higher maintenance burden

+### B.2 Recommendation Matrix
+
+| Use Case | Recommended Path | Reason |
+|----------|-----------------|--------|
+| Claude Code + VSCode | Path 1: VSCode Bridge | Simplest, full VSCode features |
+| CLI-only workflows | Path 2: Standalone LSP | No VSCode dependency |
+| Quick search across indexed code | Path 3: Index-based | Fastest response |
+| Multi-IDE support | Path 2: Standalone LSP | Standard protocol |
+| Advanced refactoring | Path 1: VSCode Bridge | Full VSCode capabilities |
+
+### B.3 Hybrid Mode (Recommended)
+
+For maximum flexibility, implement all three paths:
+
+```javascript
+// Smart routing in CCW
+function selectLSPPath(request) {
+  // 1. Try VSCode Bridge first (if available)
+  if (await checkVSCodeBridge()) {
+    return "vscode_bridge";
+  }
+  
+  // 2. Fall back to Standalone LSP
+  if (await checkStandaloneLSP(request.fileType)) {
+    return "standalone_lsp";
+  }
+  
+  // 3. Last resort: Index-based
+  return "index_based";
+}
+```

+
+## Questions for Clarification
+
+Before implementation, confirm:
+
+1. **Implementation Priority**: Start with VSCode Bridge (simpler) or Standalone LSP (more general)?
+2. **Language Priority**: Which languages are most important? (TypeScript, Python, Go, Rust, etc.)
+3. **IDE Focus**: Target VS Code first, then others?
+4. **Fallback Strategy**: Should we keep index-based search as fallback if LSP fails?
+5. **Caching**: How much should we cache LS responses?
+6. **Configuration**: Simple JSON config or more sophisticated format?
