Fix XSS filter (30 min) - **REQUIRED** 2. Fix org number validation (2 hours) - **RECOMMENDED** 3. Add database index (1 hour) - **RECOMMENDED** **Total time:** 3-4 hours to production-ready ### Short-term (This Month) 4. Add HTTP authentication (2 hours) 5. Implement rate limiting (2 hours) 6. Set up monitoring (4 hours) ### Long-term (Next Quarter) 7. Add OpenTelemetry tracing (1 week) 8. Implement CI/CD with automated tests (2 days) 9. Performance optimization (3 days) --- ## Fix Instructions All fixes are documented in detail in: → **`REMEDIATION-GUIDE.md`** Includes: - Copy-paste code examples - Step-by-step instructions - Testing procedures - Deployment checklist - Rollback procedures --- ## Test Automation ### Adding to CI/CD ```yaml # .github/workflows/test.yml name: MCP Server Tests on: [push, pull_request] jobs: test: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - uses: actions/setup-node@v3 with: node-version: '18' - run: npm ci - run: npm run build - run: npx tsx testing-audit/security-tests.ts env: SUPABASE_URL: ${{ secrets.SUPABASE_URL }} SUPABASE_SERVICE_ROLE_KEY: ${{ secrets.SUPABASE_SERVICE_ROLE_KEY }} BOLAGSVERKET_CLIENT_ID: ${{ secrets.BOLAGSVERKET_CLIENT_ID }} BOLAGSVERKET_CLIENT_SECRET: ${{ secrets.BOLAGSVERKET_CLIENT_SECRET }} ``` ### Pre-commit Hook ```bash # .git/hooks/pre-commit #!/bin/bash npm run build && npx tsx testing-audit/security-tests.ts if [ $? -ne 0 ]; then echo "❌ Security tests failed. Fix issues before committing." exit 1 fi ``` --- ## Interpreting Test Results ### Security Test Output ```bash ✅ BLOCKED: "payload" # Good - attack prevented ❌ FAILED: "payload" # Bad - attack not prevented ✅ PASS: description # Good - validation works ❌ FAIL: description # Bad - validation failed ``` ### Performance Test Output ```bash P50 (Median): 500ms # 50% of requests faster than this P95: 4,200ms # 95% of requests faster than this P99: 4,800ms # 99% of requests faster than this Success Rate: 100% # No failures Throughput: 0.96 ops/s # Operations per second ``` ### Integration Test Output ```bash ✅ PASS: Test Name # Test succeeded ❌ FAIL: Test Name # Test failed Duration: 123ms # How long test took ``` --- ## Common Issues ### "Environment variables not found" **Solution:** Tests expect `.env` file to be loaded ```bash # Make sure .env exists cp .env.example .env # Fill in actual values # Run tests npx tsx testing-audit/security-tests.ts ``` ### "Cannot find module" **Solution:** Build project first ```bash npm run build ``` ### "Permission denied: smoke-test.sh" **Solution:** Make script executable ```bash chmod +x testing-audit/smoke-test.sh ``` ### "timeout: command not found" **Solution:** macOS doesn't have `timeout` by default ```bash # Install coreutils brew install coreutils # Or use gtimeout instead gtimeout 5s node dist/index.js ``` --- ## Contact & Support **Questions about findings?** → See `COMPREHENSIVE-AUDIT-REPORT.md` sections 1-9 **Need help with fixes?** → See `REMEDIATION-GUIDE.md` for step-by-step instructions **Want to add more tests?** → Use existing test files as templates **Performance issues?** → Check section 3 of `COMPREHENSIVE-AUDIT-REPORT.md` --- ## Audit Metadata ``` Audit Date: 2025-12-01 Auditor: MCP Testing Engineer (Claude) Server Version: 0.1.0 MCP SDK Version: 1.0.4 Test Files: 4 scripts (1,460 lines) Documentation: 4 files (2,000+ lines) Total Test Coverage: ~2,500 lines of tests Execution Time: ~3 hours Issues Found: 9 (4 HIGH, 5 MEDIUM) Commendations: 20+ positive findings Overall Score: 8.2/10 ``` --- ## Version History | Version | Date | Changes | |---------|------|---------| | 1.0 | 2025-12-01 | Initial audit completed | --- **Next Review:** After fixes deployed (estimated 2025-12-08) **Quarterly Audits:** Recommended every 3 months --- END OF README
