🧠 PR Reviewer – Claude-Powered GitHub PR Review System

A Python-based intelligent tool to automate pull request analysis using the Model Context Protocol (MCP), developed by Anthropic. This system seamlessly integrates GitHub, Claude Desktop, and Notion to simplify and accelerate code review processes in modern development workflows.

🚀 Overview

Code reviews are critical but time-consuming. This system enables Claude to act as an autonomous PR reviewer via MCP, fetching code diffs, analyzing changes, and optionally documenting results in Notion.

Inspired by the guide by Bhavik Jikadara, this project shows how to set up an end-to-end Claude-powered review workflow.

✨ Features

• 🔁 Automatically fetch pull request changes via GitHub API
• 🧠 Claude Desktop integration using MCP for structured analysis
• 🧾 Optional Notion logging of PR summaries
• ⚙️ MCP server setup using fastmcp and CLI tools
• 🧪 Modular Python structure for extensions or integration with CI/CD
