# Git Hooks Implementation Summary
## 🎉 Successfully Implemented Automatic Index Synchronization
### What Was Added
1. **Git Hooks** (`mcp-index-kit/hooks/`)
- `pre-push` - Automatically uploads index changes before pushing
- `post-merge` - Automatically downloads index after pulling
- `post-checkout` - Checks index compatibility when switching branches
- `install-hooks.sh` - Script to install/uninstall hooks
2. **CLI Commands**
- `mcp-index hooks install` - Install git hooks
- `mcp-index hooks uninstall` - Remove git hooks
- `mcp-index hooks status` - Check installation and configuration
3. **Configuration Support**
- Added `auto_upload` option to `.mcp-index.json`
- Hooks respect `enabled`, `auto_upload`, and `auto_download` settings
- Safe defaults: enabled by default, can be disabled
4. **Documentation**
- Created comprehensive `docs/GIT_HOOKS_DOCUMENTATION.md`
- Updated `mcp-index-kit/README.md` with hooks section
- Updated main `README.md` to mention automatic sync
- Updated all configuration templates
### How It Works
1. **On `git push`**:
```
🔍 MCP Index: Checking for index changes...
📦 MCP Index: Index changes detected, uploading...
✓ MCP Index upload complete
```
2. **On `git pull`**:
```
🔍 MCP Index: Checking for index updates...
📦 MCP Index: Downloading latest index...
✓ Index downloaded successfully!
```
3. **On `git checkout`**:
```
🔍 MCP Index: Checking branch index...
📥 MCP Index: Index is for different commit
Current index: abc1234
Branch commit: def5678
Run 'mcp-index pull --latest' to update
```
### Key Features
- **Non-blocking**: Git operations continue even if index operations fail
- **Smart detection**: Only uploads/downloads when necessary
- **Safe installation**: Backs up existing hooks if present
- **Configurable**: Can be enabled/disabled via configuration
- **PR awareness**: Detects PR branches and suggests PR-specific indexes
### Testing
The hooks have been installed and tested in this repository:
- ✅ Installation successful
- ✅ Status command shows all hooks installed
- ✅ Configuration detected correctly
- ✅ Uninstall command available
### For End Users
Users of the mcp-index-kit can now:
1. **During initial setup**:
```bash
bash install.sh
# Will prompt: "Would you like to install git hooks for automatic index sync? [Y/n]"
```
2. **Or manually later**:
```bash
mcp-index hooks install
```
3. **Then enjoy automatic sync**:
- No need to run `mcp-index push` after changes
- No need to run `mcp-index pull` after pulling
- Everything happens automatically!
### Security
- Hooks never include sensitive files (uses secure export)
- Non-blocking design prevents workflow disruption
- All operations are logged for transparency
- Easy to disable if needed
The implementation is complete and ready for use!
