14 |
15 | ## 🚀 Quick Setup
16 |
17 | 1. **Choose your IDE** from the configurations above
18 | 2. **Copy the appropriate configuration file** to your IDE's settings directory
19 | 3. **Update the file paths** in the configuration to match your system:
20 | - Replace `/path/to/CyberMCP` with your actual CyberMCP installation path
21 | - Ensure the path points to the built `dist/index.js` file
22 | 4. **Restart your IDE**
23 |
24 | ## 📖 IDE-Specific Instructions
25 |
26 | ### Claude Desktop
27 | - **Windows**: Copy content to `%APPDATA%\Claude\claude_desktop_config.json`
28 | - **macOS**: Copy content to `~/Library/Application Support/Claude/claude_desktop_config.json`
29 | - **Linux**: Copy content to `~/.config/Claude/claude_desktop_config.json`
30 |
31 | ### Cursor IDE
32 | - Open Cursor Settings (`Ctrl/Cmd + ,`)
33 | - Add the configuration to your User Settings JSON
34 |
35 | ### Windsurf (Codeium)
36 | - Open Windsurf Settings
37 | - Add the MCP server configuration to your settings
38 |
39 | ### VS Code + Cline Extension
40 | - Install the Cline Extension from VS Code marketplace
41 | - Configure Cline Settings with the appropriate MCP server configuration
42 |
43 | ## ⚠️ Important Notes
44 |
45 | - **Build First**: Ensure you've run `npm run build` before using these configurations
46 | - **Path Updates**: Always update the placeholder paths to match your actual installation
47 | - **Restart Required**: Restart your IDE after making configuration changes
48 | - **Test Connection**: Use `npm run test-server` to verify the server works before IDE integration

It provides 14 specialized security tools and 10 resources for identifying vulnerabilities like authentication bypass, injection attacks, data leakage, and security misconfigurations.
10 |
11 | ## 🚀 Quick Start
12 |
13 | ```bash
14 | # Clone and setup
15 | git clone https://github.com/your-username/CyberMCP.git
16 | cd CyberMCP
17 | npm install
18 | npm run build
19 |
20 | # Test the server
21 | npm run test-server
22 |
23 | # Start interactive testing
24 | npm run test-interactive
25 | ```
26 |
27 | ## ✨ Features
28 |
29 | - **🔐 Authentication Testing** - JWT analysis, bypass detection, OAuth2 flows
30 | - **💉 Injection Testing** - SQL injection, XSS vulnerability detection
31 | - **📊 Data Protection** - Sensitive data exposure, path traversal checks
32 | - **⏱️ Rate Limiting** - DoS vulnerability assessment
33 | - **🛡️ Security Headers** - OWASP security header validation
34 | - **📚 Comprehensive Resources** - Security checklists and testing guides
35 |
36 | ## 🛠️ Security Tools (14 Total)
37 |
38 | | Category | Tools |
39 | |----------|-------|
40 | | **Authentication** | `basic_auth`, `token_auth`, `oauth2_auth`, `api_login`, `auth_status`, `clear_auth`, `jwt_vulnerability_check`, `auth_bypass_check` |
41 | | **Injection Testing** | `sql_injection_check`, `xss_check` |
42 | | **Data Protection** | `sensitive_data_check`, `path_traversal_check` |
43 | | **Infrastructure** | `rate_limit_check`, `security_headers_check` |
44 |
45 | ## 🎯 IDE Integration
46 |
47 | CyberMCP works with all major AI-powered IDEs:
48 |
49 | - **Claude Desktop** - Direct MCP integration
50 | - **Cursor IDE** - Built-in MCP support
51 | - **Windsurf (Codeium)** - Native MCP protocol
52 | - **VS Code + Cline** - Extension-based integration
53 |
54 | > 📖 **[Complete Setup Guide](docs/SETUP_GUIDE.md)** - Detailed configuration for each IDE
55 |
56 | ## 📋 Usage Example
57 |
58 | ```text
59 | "Use basic_auth with username 'admin' and password 'secret123'
60 | then use auth_bypass_check on https://api.example.com/users
61 | to test for authentication bypass vulnerabilities"
62 | ```
63 |
64 | The AI agent will:
65 | 1. Configure authentication credentials
66 | 2. Test the protected endpoint for bypass vulnerabilities
67 | 3. Provide detailed security analysis and recommendations

225 | # JWT Security Testing Guide
226 |
227 | ## Overview
228 | JSON Web Tokens (JWT) are a popular method for transmitting information securely between parties. However, improper implementation can lead to serious security vulnerabilities.
229 |
230 | ## Common JWT Vulnerabilities
231 |
232 | ### 1. Algorithm Confusion Attacks
233 | **What to test:**
234 | - Change the algorithm from RS256 to HS256
235 | - Set algorithm to "none"
236 | - Use empty signature
237 |
238 | **Test steps:**
239 | 1. Decode the JWT header and payload
240 | 2. Modify the "alg" field in the header
241 | 3. Re-encode and send the modified token
242 | 4. Observe if the application accepts the token
243 |
244 | ### 2. Weak Secret Keys
245 | **What to test:**
246 | - Brute force weak signing keys
247 | - Use common passwords as signing keys
248 |
249 | **Test steps:**
250 | 1. Extract the JWT signature
251 | 2. Attempt to crack the signing key using tools like hashcat
252 | 3. Use common passwords and dictionary attacks
253 |
254 | ### 3. Key Confusion
255 | **What to test:**
256 | - Use public key as HMAC secret
257 | - Confusion between different key types
258 |
259 | ### 4. JWT Injection
260 | **What to test:**
261 | - Modify claims to escalate privileges
262 | - Change user ID or role information
263 | - Extend token expiration
264 |
265 | **Example payload manipulation:**
266 | \`\`\`json
267 | {
268 | "sub": "1234567890",
269 | "name": "John Doe",
270 | "role": "admin", // Changed from "user"
271 | "iat": 1516239022
272 | }
273 | \`\`\`
274 |
275 | ## Testing Tools
276 | - jwt.io - For decoding and encoding JWTs
277 | - hashcat - For cracking weak keys
278 | - Burp Suite - JWT extension for testing
279 | - Custom scripts for automated testing
280 |
281 | ## Recommendations
282 | - Use strong, random signing keys
283 | - Implement proper algorithm validation
284 | - Set appropriate token expiration times
285 | - Validate all JWT claims server-side

316 | POST /api/login
317 | user=admin&user=guest&password=test
318 |
319 | GET /api/user?id=1&id=2
320 | \`\`\`
321 |
322 | ### 3. HTTP Method Override
323 | **What to test:**
324 | - Use different HTTP methods
325 | - X-HTTP-Method-Override header
326 | - Method override via form parameters

337 | /Admin (case variation)
338 | /admin%2f../user
339 | \`\`\`
340 |
341 | ### 5. JSON Parameter Injection
342 | **What to test:**
343 | - Array injection in JSON
344 | - Type confusion attacks
345 | - Boolean confusion
346 |
347 | **Examples:**

350 | "username": ["admin", "guest"],
351 | "password": "test"
352 | }
353 |
354 | {
355 | "admin": true,
356 | "username": "guest"
357 | }
358 | \`\`\`
359 |
360 | ## Testing Methodology
361 | 1. Map all authentication mechanisms
362 | 2. Identify authentication decision points
363 | 3. Test each bypass technique systematically

576 | X-Remote-Addr: 198.51.100.1
577 | \`\`\`
578 |
579 | ### 2. User Agent Variation
580 | **What to test:**
581 | - Different user agent strings
582 | - Empty or missing user agents
583 | - Custom user agent values
584 |
585 | ### 3. Authentication Token Cycling
586 | **What to test:**
587 | - Multiple valid tokens
588 | - Token rotation strategies
589 | - Anonymous vs authenticated limits
590 |
591 | ### 4. Distributed Requests
592 | **What to test:**
593 | - Multiple concurrent connections
594 | - Request distribution patterns
595 | - Session-based rate limiting
596 |
597 | ## Testing Methodology
598 |
599 | ### 1. Identify Rate Limiting Implementation
600 | - Send requests at normal rate
601 | - Gradually increase request frequency
602 | - Identify threshold and time windows
603 | - Analyze error responses and headers
604 |
605 | ### 2. Bypass Testing
606 | \`\`\`bash
607 | # Test header manipulation
608 | for ip in 192.168.1.{1..100}; do
609 | curl -H "X-Forwarded-For: $ip" https://api.example.com/endpoint
610 | done
611 |
612 | # Test with different user agents
613 | curl -H "User-Agent: Bot1" https://api.example.com/endpoint
614 | curl -H "User-Agent: Bot2" https://api.example.com/endpoint
615 | \`\`\`
616 |
617 | ### 3. Response Analysis
618 | - Check for rate limit headers
619 | - Analyze HTTP status codes
620 | - Monitor response times
621 | - Look for inconsistent behavior
622 |
623 | ## Rate Limit Headers to Check
624 | \`\`\`
625 | X-RateLimit-Limit: 100
626 | X-RateLimit-Remaining: 99
627 | X-RateLimit-Reset: 1640995200
628 | Retry-After: 60
629 | \`\`\`
630 |
631 | ## Advanced Testing
632 |
633 | ### 1. Race Condition Testing
634 | - Send simultaneous requests
635 | - Test for inconsistent counting
636 | - Look for temporary bypass windows
637 |
638 | ### 2. Algorithm Analysis
639 | - Token bucket vs leaky bucket
640 | - Fixed window vs sliding window
641 | - Per-user vs global limits
642 |
643 | ### 3. Resource-Specific Testing
644 | - Different endpoints may have different limits
645 | - POST vs GET request limits
646 | - File upload rate limiting
647 |
648 | ## Tools and Scripts
649 | - Burp Suite Intruder
650 | - Custom rate testing scripts
651 | - Apache Bench (ab)
652 | - wrk load testing tool
653 | - Custom Python/Node.js scripts
654 |
655 | ## Expected Behaviors
656 | - Consistent rate limit enforcement
657 | - Proper error messages (HTTP 429)
658 | - Informative rate limit headers
659 | - Graceful degradation under load
