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

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
