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:

# 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:

{
  "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):

   mkdir .claude
   

2. Create or edit .claude/config.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:

{
  "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:

/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

<details> <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:

CODERABBIT_LOG_LEVEL=debug npx coderabbitai-mcp
