- **Smart Filtering**: Advanced gitignore integration and size-based filtering

### 🔍 Advanced Search & Analysis
- **Local Semantic Search**: FAISS-based vector search with zero cloud dependencies (p50 < 20ms after model loaded)
- **Async Search**: Non-blocking search operations with real-time progress tracking
- **Multi-Pattern Search**: Concurrent search across multiple patterns with scoped results
- **Intelligent Caching**: 90% faster repeated searches with LRU cache
- **Fuzzy Search**: Native fuzzy matching with safety checks
- **Search Result Pagination**: Efficient handling of large result sets

### 🛠️ Complete Feature Set
- **Progress Tracking**: Real-time progress events with cancellation support
- **Performance Monitoring**: Comprehensive metrics and Prometheus export

## 📦 Installation & Setup

### 🚀 **Quick Start**

**For immediate use with AI applications:**
```bash
uvx git+https://github.com/scooter-lacroix/code-indexer.git
```

**For package installation:**
```bash
uv add code-index-mcp
# or
pip install code-index-mcp
```

**For local vector search support (recommended):**
```bash
# Install FAISS and sentence-transformers dependencies
uv pip install 'faiss-cpu>=1.7.4' 'sentence-transformers>=2.2.0' 'numpy>=1.24.0'
```

### 🏗️ **Comprehensive Setup (PostgreSQL + Elasticsearch)**

**1. Start Required Services:**
```bash
# Using Podman Compose (recommended for AMD/CPU-only systems)
podman compose up -d

# Or using Docker Compose (alternative)
docker compose up -d

# Stop any local Elasticsearch before starting containers
sudo systemctl stop elasticsearch 2>/dev/null || true
```

This will start:
- PostgreSQL on port 5432

### 🛠️ CLI & Skills
We provide a dedicated CLI tool `code-search` and a Skill definition for agents to autonomously navigate your codebase.

**1. CLI Tool:**
```bash
# Search code (Semantic + Symbolic)
code-search "How does the indexing work?"

# Ask questions (RAG)
code-search --answer "Explain the core engine architecture"
```

**2. Agent Configuration:**
Run the installation helper to get configuration snippets for your agent:
```bash
python src/scripts/install_agent.py [claude-code|openai|vscode|all]
```

**3. Skill Integration:**
For agents that support Skills or System Prompts, refer to `plugins/code_indexer/skills/code-search/SKILL.md` for the optimal prompt to ensure the agent uses the Unified Engine correctly.

## 🛠️ Available Tools

The Code Index MCP server provides **9 consolidated mega-tools** for comprehensive code analysis and management. These mega-tools use action-based routing to streamline operations while preserving all functionality from the original 50+ individual tools.

### 🌟 **Mega-Tools Architecture**

Each mega-tool accepts an `action`, `operation`, or `type` parameter that routes to the specific functionality you need:

| Mega-Tool | Actions/Operations/Modes | Consolidates |

| **search_content** | search, find, rank | 3 tools |
| **modify_file** | write, diff, insert, replace | 4 tools |
| **manage_files** | delete, rename, revert, history | 4 tools |
| **get_diagnostics** | memory, index, backend, performance, operations, settings, ignore, filtering, ranking | 9 tools |
| **manage_memory** | cleanup, configure, export | 3 tools |
| **manage_operations** | list, cancel, cleanup | 4 tools |

### 📚 **Migration from Old Tools**

If you were using the previous 50+ individual tools, see the **[Migration Guide](conductor/tracks/mcp_consolidation_local_vector_20251230/MIGRATION_GUIDE.md)** for a complete mapping of old tool names to the new mega-tools.

**Quick Migration Examples:**
- `set_project_path()` -> `manage_project(action="set_path", path=...)`
- `search_code_advanced()` -> `search_content(action="search", pattern=...)`
- `write_to_file()` -> `modify_file(operation="write", path=..., content=...)`
- `get_file_history()` -> `manage_files(action="history", file_path=...)`

**📖 Complete Documentation**: See [docs/TOOLS_LIST.md](docs/TOOLS_LIST.md) for detailed tool reference with examples and system prompt templates.

## Common Workflows and Examples

Here's a typical workflow for using Code Index MCP with an AI assistant like Claude.

### 1. Set Project Path & Initial Indexing

This is the first and most important step. When you set the project path, the server automatically creates a file index for the first time or loads a previously cached one.

**Example Prompt:**
```
Please set the project path to C:\Users\username\projects\my-react-app
```

**Mega-tool used:**
```python
manage_project(action="set_path", path="C:\\Users\\username\\projects\\my-react-app")
```

### 2. Refresh the Index (When Needed)

If you make significant changes to your project files after the initial setup, you can manually refresh the index to ensure all tools are working with the latest information.

**Example Prompt:**
```
I've just added a few new components, please refresh the project index.
```

**Mega-tool used:**
```python
manage_project(action="refresh")
```

### 3. Explore the Project Structure

Once the index is ready, you can find files using patterns (globs) to understand the codebase and locate relevant files.

**Example Prompt:**
```
Find all TypeScript component files in the 'src/components' directory.
```

**Mega-tool used:**
```python
search_content(action="find", pattern="src/components/**/*.tsx")
```

### 4. Analyze a Specific File

Before diving into the full content of a file, you can get a quick summary of its structure, including functions, classes, and imports.

**Example Prompt:**
```
Can you give me a summary of the 'src/api/userService.ts' file?
```

**Mega-tool used:**
```python
read_file(mode="smart", file_path="src/api/userService.ts", include_content=True)
```

### 5. Search for Code

With an up-to-date index, you can search for code snippets, function names, or any text pattern to find where specific logic is implemented.

**Example: Simple Search**
```
Search for all occurrences of the "processData" function.
```
```python
search_content(action="search", pattern="function processData")
```

**Example: Search with Fuzzy Matching**
```
I'm looking for a function related to user authentication, it might be named 'authUser', 'authenticateUser', or something similar. Can you do a fuzzy search for 'authUser'?
```
```python
search_content(action="search", pattern="authUser", fuzzy=True)
```

**Example: Search within Specific Files**
```
Search for the string "API_ENDPOINT" only in Python files.
```
```python
search_content(action="search", pattern="API_ENDPOINT", file_pattern="*.py")
```

### 6. Modify Files

When you need to make changes to your code, use the modify_file mega-tool with different operations.

**Example: Write a New File**
```
Create a new file 'src/utils/helpers.ts' with utility functions.
```
```python
modify_file(
    operation="write",
    path="src/utils/helpers.ts",
    content="export function formatDate(date: Date): string { ... }",
    line_count=5
)
```

**Example: Search and Replace**
```
Replace all occurrences of 'TODO' with 'FIXME' in the api.ts file.
```
```python
modify_file(
    operation="replace",
    path="src/api.ts",
    search="TODO",
    replace="FIXME"
)
```

### 7. Get System Diagnostics

Monitor the health and performance of your code indexing system.

**Example: Check Memory Usage**
```
How much memory is the indexer currently using?
```
```python
get_diagnostics(type="memory")
```

**Example: View Index Statistics**
```
Show me the current index statistics.
```
```python
get_diagnostics(type="index", force_refresh=True)
```

### 8. Manage File Versions

Track and revert changes to files using the version history system.

**Example: Get File History**
```
Show me the change history for config.json.
```
```python
manage_files(action="history", file_path="config.json")
```

**Example: Revert to Previous Version**
```
Revert main.py to the version from yesterday.
```
```python
manage_files(
    action="revert",
    file_path="main.py",
    timestamp="2024-01-15T10:30:00"
)
```

## Development

### Building from Source
