MCP (Model Context Protocol) server for code review. Enables AI assistants to review GitHub/GitLab Pull Requests and Merge Requests.

## ✨ Features

- 🔍 **Multi-platform**: Supports both GitHub and GitLab (including self-hosted)
- 🚀 **Multiple Transports**: Supports stdio, SSE, and WebSocket protocols
- 📦 **Easy Install**: Quick install via `uvx` or `pip`
- 🐳 **Containerized**: Docker image available
- ☁️ **Cloud Deploy**: One-click Smithery deployment
- 🔒 **Security First**: Environment variable configuration, no data persistence

## 🚀 Quick Start

### Option 1: Using uvx (Recommended)

```bash
# Run directly, no installation needed
uvx code-review-mcp
```

### Option 2: Using pip

```bash
pip install code-review-mcp

# Run the server
code-review-mcp

# (Optional) Install Cursor rules to your project
code-review-mcp init-rules
```

### Option 3: From Source

```bash
git clone https://github.com/OldJii/code-review-mcp.git
cd code-review-mcp
pip install -e .
code-review-mcp
```

## 🔧 Configuration

### Environment Variables

| Variable | Description | Required |
|----------|-------------|----------|
| `GITHUB_TOKEN` | GitHub personal access token | When using GitHub |
| `GITLAB_TOKEN` | GitLab personal access token | When using GitLab |
| `GITLAB_HOST` | GitLab host URL | For self-hosted (default: gitlab.com) |

### Getting Tokens

**GitHub**

```bash
# Option 1: Using gh CLI (Recommended)
brew install gh
gh auth login

# Option 2: Manual Token Creation
# Visit https://github.com/settings/tokens
# Create Personal Access Token with 'repo' scope
export GITHUB_TOKEN="your-token-here"
```

**GitLab**

```bash
# Option 1: Using glab CLI (Recommended)
brew install glab
glab auth login

# For self-hosted GitLab
glab auth login --hostname gitlab.yourcompany.com

# Option 2: Manual Token Creation
# Visit GitLab -> Settings -> Access Tokens
# Create token with 'api' scope
export GITLAB_TOKEN="your-token-here"
export GITLAB_HOST="gitlab.yourcompany.com"  # For self-hosted
```

## 🎯 Cursor Rules (Recommended)

This package includes built-in code review rules for Cursor IDE. Install them to your project with one command:

```bash
# Install rules to current project
code-review-mcp init-rules

# Install to a specific directory
code-review-mcp init-rules --target /path/to/project

# Overwrite existing rules
code-review-mcp init-rules --force

# List available rules
code-review-mcp list-rules
```

After installation, the rules will be available in your project's `.cursor/rules/` directory:
- `code-review.mdc` - Chinese version
- `code-review-en.mdc` - English version

### Customizing Rules

The installed rules are general templates. You can customize them for your project:

- Priority definitions
- Checklist items
- Comment format
- Deduplication rules
