# CodeRabbit MCP Server

A Model Context Protocol (MCP) server for interacting with CodeRabbit AI reviews on GitHub pull requests. This server enables Large Language Models (LLMs) to analyze, understand, and implement CodeRabbit suggestions programmatically.

## Features

- **Get CodeRabbit Reviews**: Retrieve all CodeRabbit reviews for a specific pull request
- **Review Details**: Get detailed information about specific reviews including configuration and files reviewed
- **Extract Comments**: Get individual line comments with AI prompts and suggestions
- **Comment Details**: Deep dive into specific comments with context and fix examples
- **Resolve Comments**: Mark comments as addressed, won't fix, or not applicable
- **Automated Workflow Prompt**: Use `/coderabbit-review` slash command for complete review processing

## Quick Start

### Installation (NPX - Recommended)

No installation required! Run directly with npx:

```bash
# Install the latest stable version explicitly
npx coderabbitai-mcp@latest
```

### Prerequisites

1. **GitHub Personal Access Token**: Create at <https://github.com/settings/tokens>
   - Required scopes: `repo` (for private repos) or `public_repo` (for public only)
2. **Node.js 18+**: Required for running the server

## Configuration

### Claude Desktop Configuration

To use the CodeRabbit MCP server in Claude Desktop, add it to your configuration file:

**Configuration file locations:**
- **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows**: `%APPDATA%/Claude/claude_desktop_config.json`
- **Linux**: `~/.config/Claude/claude_desktop_config.json`

**Step-by-step setup:**

1. Open your Claude Desktop configuration file (create it if it doesn't exist)
2. Add the CodeRabbit MCP server configuration:

```json
{
  "mcpServers": {
    "coderabbitai": {
      "command": "npx",
      "args": ["coderabbitai-mcp@latest"],
      "env": {
        "GITHUB_PAT": "ghp_your_token_here"
      }
    }
  }
}
```

3. Replace `ghp_your_token_here` with your actual GitHub Personal Access Token
4. Save the file and restart Claude Desktop

### Claude Code Configuration

To use the CodeRabbit MCP server in Claude Code, configure it in your project:

**Step-by-step setup:**

1. Create a `.claude` directory in your project root (if it doesn't exist):
   ```bash
   mkdir .claude
   ```

2. Create or edit `.claude/config.json`:

```json
{
  "mcpServers": {
    "coderabbitai": {
      "command": "npx",
      "args": ["coderabbitai-mcp@latest"],
      "env": {
        "GITHUB_PAT": "ghp_your_token_here"
      }
    }
  }
}
```

3. Replace `ghp_your_token_here` with your actual GitHub Personal Access Token
4. The server will be available next time you start Claude Code in this project

**Pro tip**: For security, you can use environment variables instead of hardcoding the token:

```json
{
  "mcpServers": {
    "coderabbitai": {
      "command": "npx",
      "args": ["coderabbitai-mcp@latest"],
      "env": {
        "GITHUB_PAT": "${GITHUB_PAT}"
      }
    }
  }
}
```

Then set the `GITHUB_PAT` environment variable in your shell before starting Claude Code.

## Usage

### Automated Review Processing (Recommended)

Use the built-in MCP prompt for complete workflow automation:

```text
/coderabbit-review owner:bradthebeeble repo:wiseguys pullNumber:15
```

This prompt automatically:
- Finds and analyzes CodeRabbit reviews
- Classifies issues by priority (high/medium/low)
- Gets your approval before making changes
- Systematically implements fixes
- Marks resolved comments in CodeRabbit
- Provides a completion summary

<summary>Troubleshooting</summary>

### Common Issues

**Server not loading (NPX):**
- Verify Node.js 18+ is installed: `node --version`
- Test npx execution manually: `npx coderabbitai-mcp` 
- Check your internet connection (npx downloads the latest version)

**GitHub API errors:**
- Verify your GitHub token has the required permissions
- Check that you have access to the repositories you're querying

**No CodeRabbit reviews found:**
- Verify the PR has CodeRabbit reviews (check GitHub web interface)
- Ensure you're using the correct owner/repo/pullNumber

### Debug Mode

Enable debug logging:

```bash
CODERABBIT_LOG_LEVEL=debug npx coderabbitai-mcp
```

</details>

## Integration Requirements

### Supported AI Clients

- **Claude Desktop**: Full support with configuration
- **Claude Code**: Project-level MCP integration with `/coderabbit-review` prompt
- **Other MCP Clients**: Any client supporting the Model Context Protocol

### Authentication

The GitHub Personal Access Token needs these permissions:
- `repo` (for private repositories) or `public_repo` (for public only)
- `read:org` (if accessing organization repositories)

## Architecture

- **TypeScript**: Fully typed implementation with Zod validation
- **MCP SDK**: Built on the official Model Context Protocol SDK
- **Modular Design**: Each tool is implemented in its own module
- **MCP Prompts**: Automated workflows available as slash commands

## API Rate Limits

The server respects GitHub's API rate limits:
- 5,000 requests/hour for authenticated requests
- Automatically handles rate limit responses

## Contributing

1. Fork the repository
2. Create a feature branch: `git checkout -b feature-name`
