# 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/`

**✅ FILES CREATED/MODIFIED**:
- `scripts/qa-metrics-collector.js` ✅ (NEW) - 600+ lines of comprehensive metrics collection
- `docs/QA/metrics/` directory ✅ (NEW) - For storing historical metrics data

### DASHBOARD-AGENT-1: Create Statistics Dashboard
**Status**: ✅ COMPLETED
**Model**: Sonnet 3.5

| Response Time | 📈 increasing (16ms, 12%) | Average API response speed |
## 📊 Performance Charts
```
**✅ FILES CREATED**:
- `scripts/qa-dashboard-generator.js` ✅ (NEW) - 590+ lines comprehensive dashboard generator
- `docs/QA/METRICS_DASHBOARD.md` ✅ (AUTO-GENERATED) - Live dashboard with trends and alerts
## Success Criteria
- [⚠️] QA tests actually test the MCP server (Major infrastructure done, API endpoint issue remains)
- [✅] Performance metrics collected on every run (COMPLETED by METRICS-AGENT-1)
- [✅] Metrics saved for historical comparison (COMPLETED - saved to docs/QA/metrics/)
- [✅] Dashboard shows trends across PRs (COMPLETED by DASHBOARD-AGENT-1)
- [ ] CI workflow updated to support this
## Next Steps Required
**IMMEDIATE PRIORITY**: Resolve Inspector API endpoint issue
1. **Research Inspector API Documentation**: Find correct endpoint specification
2. **Alternative Approaches**: Consider direct MCP SDK testing if Inspector API remains problematic
3. **Session Management**: Inspector may require session creation before tool calls
4. **WebSocket vs HTTP**: Inspector might use WebSocket for MCP communication
**Implementation Notes**:
```javascript
// Current working server startup (✅ DONE)
const mcpProcess = spawn('npx', ['@modelcontextprotocol/inspector', 'node', 'dist/index.js'], {
env: { DANGEROUSLY_OMIT_AUTH: 'true' }
});
// 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)

**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
