AI-powered Cybersecurity API Testing with Model Context Protocol (MCP)

CyberMCP is a Model Context Protocol (MCP) server that enables AI agents to perform comprehensive security testing on backend APIs. It provides 14 specialized security tools and 10 resources for identifying vulnerabilities like authentication bypass, injection attacks, data leakage, and security misconfigurations.

🚀 Quick Start

# Clone and setup
git clone https://github.com/your-username/CyberMCP.git
cd CyberMCP
npm install
npm run build

# Test the server
npm run test-server

# Start interactive testing
npm run test-interactive

✨ Features

• 🔐 Authentication Testing - JWT analysis, bypass detection, OAuth2 flows
• 💉 Injection Testing - SQL injection, XSS vulnerability detection
• 📊 Data Protection - Sensitive data exposure, path traversal checks
• ⏱️ Rate Limiting - DoS vulnerability assessment
• 🛡️ Security Headers - OWASP security header validation
• 📚 Comprehensive Resources - Security checklists and testing guides

🛠️ Security Tools (14 Total)

🎯 IDE Integration

CyberMCP works with all major AI-powered IDEs:

• Claude Desktop - Direct MCP integration
• Cursor IDE - Built-in MCP support
• Windsurf (Codeium) - Native MCP protocol
• VS Code + Cline - Extension-based integration

📖 Complete Setup Guide - Detailed configuration for each IDE

📋 Usage Example

"Use basic_auth with username 'admin' and password 'secret123' 
then use auth_bypass_check on https://api.example.com/users 
to test for authentication bypass vulnerabilities"

The AI agent will:

1. Configure authentication credentials
2. Test the protected endpoint for bypass vulnerabilities
3. Provide detailed security analysis and recommendations
