CyberMCP - Cybersecurity API Testing with MCP
LocalAbout CyberMCP - Cybersecurity API Testing with MCP
CyberMCP is an MCP server for AI agents testing backend API security. It exposes specialized checks for common vulnerabilities along with security resources and guides.
Key features
- 01Authentication and bypass checks
- 02SQL injection and XSS checks
- 03Sensitive data and path traversal checks
- 04Rate-limit and security-header checks
- 05Security checklists and guides
Use cases
- 01Assess authentication on a protected API endpoint
- 02Check an API for injection vulnerabilities
- 03Review API data exposure and security headers
MCP support
Exposes 14 security testing tools and 10 resources for MCP clients, covering API authentication, injection, data protection, rate limiting, and security headers.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

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)
| Category | Tools |
|---|---|
| Authentication | basic_auth, token_auth, oauth2_auth, api_login, auth_status, clear_auth, jwt_vulnerability_check, auth_bypass_check |
| Injection Testing | sql_injection_check, xss_check |
| Data Protection | sensitive_data_check, path_traversal_check |
| Infrastructure | rate_limit_check, security_headers_check |
🎯 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:
- Configure authentication credentials
- Test the protected endpoint for bypass vulnerabilities
- Provide detailed security analysis and recommendations
📊 Testing & Validation

Comments
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
