🛡️ CodeSentry MCP

AI-Powered Code Review Assistant using Model Context Protocol

CodeSentry is an intelligent code review assistant that integrates with AI systems through the Model Context Protocol (MCP). It provides comprehensive analysis of your codebase, identifying security vulnerabilities, performance bottlenecks, code quality issues, and documentation gaps.

✨ Features

• 🔒 Security Analysis - Detect OWASP Top 10 vulnerabilities and security anti-patterns
• ⚡ Performance Analysis - Identify bottlenecks and optimization opportunities
• 🎯 Code Quality - Find code smells, complexity issues, and maintainability problems
• 📚 Documentation Review - Check for missing or outdated documentation
• 🤖 AI Integration - Natural language explanations and suggestions
• 🔗 GitHub Integration - Automated PR reviews and status checks
• 🧪 Live Testing - Built-in MCP client for immediate feedback

🚀 Quick Start

Prerequisites

• Node.js 18+
• Git
• An AI assistant that supports MCP (Claude, etc.)

Installation

Usage with MCP

1. Add to Claude Desktop (macOS):

{
  "mcpServers": {
    "codesentry": {
      "command": "node",
      "args": ["/path/to/codesentry-mcp/dist/index.js"],
      "env": {}
    }
  }
}

2. Test the connection:

Ask Claude: "Use the ping tool to test CodeSentry"

3. Analyze a repository:

Ask Claude: "Use CodeSentry to analyze the repository at /path/to/your/project"
