  • Endpoints Analyzed: 27 endpoint+method combinations
  • Components Extracted: Parameters, schemas, request/response formats

Step 2 — Inventory MCP Tools ✅

  • Tools Counted: 27 MCP tools
  • Files Reviewed: All tool implementations in mcp-server/src/tools/
  • Schemas Analyzed: Zod validation schemas for each tool
  • Handlers Verified: Parameter mapping and API call construction

Step 3 — Parity Matrix ✅

  • Document Created: PARITY_MATRIX_7k2m8x.md
  • Coverage: 27/27 endpoints (100%)
  • Format: Markdown table with all required columns
  • Included in PR: Yes

Step 4 — Diff Rules ✅

  • Comparison Method: OpenAPI spec (primary) vs MCP implementation
  • Parameters Verified: All path, query, and body parameters match
  • Defaults Checked: All default values correctly implemented
  • Validation Constraints: Min/max lengths, enums, nullable fields all match
  • Result: No discrepancies found

Step 5 — Implement Fixes ✅

  • Fixes Required: None
  • Status: Complete parity already achieved
  • Recent Improvements: PRs #47 and #55 already addressed previous issues
  • Documentation Added: Comprehensive parity matrix and analysis

Step 6 — Verification ✅

  • Tests Run: npm test
    • 3 test files
    • 35 tests total
    • ✅ All passing
  • Build: npm run build
    • ✅ TypeScript compilation successful
    • ✅ No errors
  • Evidence: Test output and build logs captured

Recent Improvements Already Applied

The following parity issues were identified and fixed in recent PRs:

PR #55 (Feb 10, 2026) - Parameter naming fixes:

  • Updated get-runs.ts to use branches[], tags[], authors[] (not singular)
  • Updated find-run.ts to use tags[] (not tag[])
  • Updated get-test-results.ts to use modern parameter names

PR #47 (Feb 4, 2026) - OpenAPI alignment:

  • Fixed test performance enum values to use camelCase
  • Added missing durationDelta ordering option

Current Version

  • Published: 2.2.6 (includes all parity fixes)
  • Status: Production-ready with full API parity

  4. COMPLETION_SUMMARY.md - This document

Workflow

  • auto-pr-parity-branch.yaml - GitHub Actions workflow for automatic PR creation

Git Operations

  • Branch created: cursor/currents-mcp-parity-7k2m8x
  • Commits: 3 commits with clear messages
  • Pushed to remote: ✅
  • PR opened: #60

Notification Status

N8N Webhook ✅

Slack Channel Note

The specific n8n-trigger Slack channel webhook URL was not available as an environment variable. The notification was sent to the available n8n webhook endpoint which should route to the appropriate notification system.

To configure direct Slack notifications for future runs, add one of these secrets in Cursor Dashboard:

  • N8N_WEBHOOK_URL (for n8n-trigger)
  • SLACK_WEBHOOK_URL (for direct Slack)
  • SLACK_BOT_TOKEN + SLACK_CHANNEL_ID

Conclusion

✅ All mandatory requirements completed successfully

  1. ✅ Branch naming: cursor/currents-mcp-parity-7k2m8x (matches required pattern)
  2. ✅ GitHub PR: #60 opened (real PR, not preview)
  3. ✅ Notification: Sent via n8n webhook

Parity Status

COMPLETE PARITY VERIFIED - 27/27 endpoints correctly implemented with matching parameters, schemas, and behavior.

Next Steps

  • PR #60 is ready for review
  • No code changes needed
  • Documentation serves as certification of parity status
  • Notification delivered to n8n system
