# QA MCP Server Testing & Metrics Coordination **Orchestrator**: Opus 4.1 **Date**: August 22, 2025 **Branch**: feature/qa-mcp-testing-metrics **Status**: IN PROGRESS ## Critical Problem QA tests are running in CI but showing 0% success rate because: - No MCP server is running - No tools are being discovered - Tests skip everything - We're not getting any real metrics This makes the QA tests essentially useless for quality assurance. ## Mission Objectives 1. **Fix QA tests to actually spin up and test the MCP server** 2. **Collect performance metrics on every test run** 3. **Create statistics/dashboard showing trends across PRs** ## Agent Assignments ### MCP-TEST-AGENT-1: Fix QA to Test Real MCP Server **Status**: IN PROGRESS (Major improvements made, Inspector API challenges remain) **Model**: Claude Sonnet 4.0 **Task**: Make QA tests actually test the MCP server **Specific Tasks**: 1. Update `scripts/qa-test-runner.js` to: - Start the MCP server before tests - Use the Inspector API to connect - Ensure server is ready before testing - Properly shut down server after tests 2. Fix tool discovery to work with running server 3. Ensure tests actually execute (not skip) 4. Handle CI environment properly **Key Implementation**: ```javascript // Start MCP server const mcpProcess = spawn('node', ['dist/index.js'], { stdio: ['pipe', 'pipe', 'pipe'], env: { ...process.env, TEST_MODE: 'true' } }); // Wait for server ready await waitForServerReady(); // Run tests via Inspector // ... existing test logic ... // Cleanup mcpProcess.kill(); ``` **Files Modified**: - `scripts/qa-test-runner.js` ✅ COMPLETED - Major refactoring done - `scripts/qa-utils.js` ✅ COMPLETED - Updated for flexible auth - `.github/workflows/qa-tests.yml` (may need adjustments) **Progress Made**: ✅ **Server Startup Logic**: Implemented complete MCP Inspector startup/shutdown ✅ **Process Management**: Added proper process spawning, monitoring, and cleanup ✅ **Port Detection**: Dynamic port detection from Inspector output ✅ **Authentication**: Implemented auth-disabled mode for testing ✅ **Error Handling**: Enhanced error handling and debugging ✅ **Timing**: Improved server readiness detection with retries **Current Status**: - MCP Server ✅ Starts correctly via Inspector - Inspector Process ✅ Spawns and reports listening on port - HTTP Server ✅ Accepts connections - API Endpoint ⚠️ **ISSUE**: Inspector API endpoint discovery incomplete - Tool Discovery ❌ **BLOCKED**: Cannot find correct API endpoint **Technical Details**: - Inspector starts successfully with DANGEROUSLY_OMIT_AUTH=true - Server listens on expected port (6277 or dynamic) - HTTP requests reach the server but return 404 for all tested endpoints - Tested endpoints: `/message`, `/api/message`, `/sessions`, `/rpc` - Need to identify correct Inspector API endpoint for MCP communication ### METRICS-AGENT-1: Add Performance Metrics Collection **Status**: ✅ COMPLETED **Model**: Sonnet 3.5 **Task**: Implement Issue #680 - performance metrics **✅ COMPLETED TASKS**: 1. ✅ Created `scripts/qa-metrics-collector.js` with comprehensive metrics collection utilities 2. ✅ Added timing to all QA operations in all test scripts 3. ✅ Collect metrics: - Response times (P50, P95, P99) ✅ - Tool discovery time ✅ - Individual test durations ✅ - Memory usage snapshots ✅ - Server startup timing ✅ 4. ✅ Generate metrics report with performance insights 5. ✅ Save metrics to JSON for trending in `docs/QA/metrics/` **✅ INTEGRATION COMPLETED**: - `scripts/qa-test-runner.js` ✅ Full metrics integration - `scripts/qa-simple-test.js` ✅ Full metrics integration - `scripts/qa-direct-test.js` ✅ Full metrics integration - `scripts/qa-element-test.js` ✅ Full metrics integration - `scripts/qa-github-integration-test.js` ✅ Full metrics integration **✅ IMPLEMENTED METRICS STRUCTURE**: ```javascript const metrics = { timestamp: new Date().toISOString(), test_run_id: 'QA_RUNNER_1234567890', pr_number: process.env.PR_NUMBER, commit_sha: process.env.GITHUB_SHA, branch: process.env.GITHUB_HEAD_REF, environment: { ci: process.env.CI === 'true', node_version: process.version, platform: process.platform }, performance: { total_duration_ms: 4500, tool_discovery_ms: 125, server_startup_ms: 2300, percentiles: { p50: 85, p95: 180, p99: 350, min: 15, max: 500, avg: 110 }, tests: { 'list_elements': { executions: [45, 52, 38], avg_duration_ms: 45, success_count: 3, failure_count: 0 } }, memory_usage: { peak_rss: 89123456, peak_heap: 45678901, snapshots_count: 5 } }, success_metrics: { total_tests: 25, successful_tests: 23, failed_tests: 1, skipped_tests: 1, success_rate: 95, tools_available: 42 }, insights: [ { type: 'performance', severity: 'medium', message: 'P95 response time is 180ms', recommendation: 'Monitor for regression trends' } ] };

// Working: Inspector starts, server ready, port detection // Failing: HTTP POST to any tested endpoint returns 404 // Need: Correct endpoint for tools/list and tools/call ``` ## Testing Commands ```bash # Test locally with server (now includes automatic metrics collection) npm run build node scripts/qa-test-runner.js # Test other QA scripts (all include metrics now) node scripts/qa-simple-test.js node scripts/qa-direct-test.js node scripts/qa-element-test.js node scripts/qa-github-integration-test.js # Check metrics output ls -la docs/QA/metrics/ # Generate dashboard (ready for implementation) node scripts/qa-dashboard-generator.js ``` ## Priority Notes **CRITICAL**: Without this, our QA tests are providing false confidence. Every PR shows "passing" QA tests but they're not actually testing anything! ## Integration with Existing Issues - Addresses Issue #667 (tool validation) - Implements Issue #680 (performance metrics) - Partially addresses Issue #679 (stores results for comparison) --- **Last Updated**: August 22, 2025, 6:30 PM EST by DASHBOARD-AGENT-1 (Claude Sonnet 4) **Key Achievements**: - **MCP-TEST-AGENT-1**: Transformed QA tests from 0% connection rate to functional server startup with proper process management. The infrastructure is now in place to actually test the MCP server - only the API endpoint discovery remains to be resolved. - **METRICS-AGENT-1**: ✅ **COMPLETED** comprehensive performance metrics collection implementation across all QA test scripts. Issue #680 is now fully implemented with detailed performance tracking, memory monitoring, and historical trend analysis capabilities. - **DASHBOARD-AGENT-1**: ✅ **COMPLETED** comprehensive QA metrics dashboard system with automatic updates, trend analysis, performance alerts, and ASCII chart visualization. Dashboard auto-generates after each test run providing real-time insights into QA performance and reliability trends. ## Session Notes - **August 22, 2025**: [SESSION_NOTES_2025_08_22_QA_INFRASTRUCTURE.md](./SESSION_NOTES_2025_08_22_QA_INFRASTRUCTURE.md) - Built comprehensive infrastructure but Inspector API communication still broken - Need to research correct endpoints for next session ## Current Blocker **Cannot communicate with MCP Inspector API** - The Inspector starts but we can't find the correct API endpoints for tools/list and tools/call --- **Last Updated**: August 22, 2025, 11:30 AM EST
