Peekaboo MCP

# Production Readiness Review - peekaboo-mcp **Date**: December 2024 **Reviewer**: AI Assistant **Overall Readiness**: 88% ## Executive Summary The peekaboo-mcp package is **88% production-ready**. It has excellent security, comprehensive testing, and solid core functionality. However, there are critical issues with integration tests and package metadata that must be resolved before production deployment. ## Detailed Assessment ### ✅ Strengths (What's Working Well) 1. **Security** (98/100) - Robust path traversal protection - Automatic project root detection prevents unauthorized access - No write operations possible (read-only by design) - Comprehensive security test coverage 2. **Core Functionality** (95/100) - All MCP protocol methods properly implemented - Good error handling with appropriate error codes - Resource management (timeouts, size limits) working correctly - Search functionality (path and content) implemented 3. **Test Coverage** (85/100) - 186 out of 191 tests passing - Comprehensive unit tests for all components - Edge cases and stress tests included - Security tests are thorough 4. **Documentation** (92/100) - Clear README with examples - API documentation complete - Security considerations documented - Breaking changes guide provided ### ❌ Critical Issues (Must Fix) 1. **Integration Tests Failing** - 5 out of 6 integration tests fail with "Cannot read properties of undefined (reading 'parse')" - Test server implementation causes path traversal errors - This blocks confidence in client-server interaction 2. **Package Metadata** ```json "author": "Your Name", // Placeholder "repository": { "type": "git", "url": "https://github.com/yourusername/peekaboo-mcp.git" // Placeholder } ``` 3. **No Test Coverage Reports** - Coverage directory is missing - Can't verify actual coverage percentages ### ⚠️ Important Issues (Should Fix) 1. **Console Logging in Production** - 3 instances of `console.error` in index.ts - Should use proper logging library 2. **Missing Build Validation** - No prepublish/prepublishOnly scripts - Could lead to publishing broken builds 3. **No Version History** - Missing CHANGELOG.md - Users can't track changes between versions ### 💡 Recommendations for 100% Readiness #### Immediate Actions (Critical): 1. **Fix Integration Tests** ```typescript // Fix test-server.ts to properly handle security // Or mock the security checks appropriately for testing ``` 2. **Update package.json** ```json { "author": "David Strasser", "repository": { "type": "git", "url": "https://github.com/davstr1/peekabooMCP.git" }, "keywords": ["mcp", "model-context-protocol", "filesystem", "readonly"], "scripts": { "prepublishOnly": "npm run build && npm test" } } ``` 3. **Fix Coverage Generation** - Ensure vitest coverage reporter is properly configured - Add coverage directory to .gitignore #### Short-term Actions (Important): 1. **Replace Console Logging** ```typescript // Instead of console.error import { createLogger } from './logger'; const logger = createLogger('peekaboo-mcp'); logger.error('Failed to start server:', error); ``` 2. **Add CHANGELOG.md** ```markdown # Changelog ## [2.0.0] - 2024-12-XX ### Breaking Changes - Removed PEEKABOO_ROOT environment variable - Direct execution no longer supported ### Added - Search tools (search_path, search_content) - Resource management (timeouts, size limits) - Comprehensive test suite ``` #### Long-term Improvements: 1. **Add Monitoring Hooks** - Performance metrics - Error tracking - Usage analytics (optional) 2. **Add Health Check** ```typescript server.setRequestHandler('health/check', async () => ({ status: 'healthy', version: '2.0.0', uptime: process.uptime() })); ``` ## Risk Assessment - **Low Risk**: Core functionality, security, and most tests are solid - **Medium Risk**: Integration test failures could hide client-server issues - **High Risk**: None identified ## Conclusion The package is very close to production-ready. With 2-3 hours of work to fix the critical issues, it would be fully ready for production deployment. The security implementation is excellent, and the core functionality is solid. The main blockers are technical debt items (integration tests, package metadata) rather than fundamental design issues. **Recommended Action**: Fix critical issues before v2.0.0 release.
