🛡️ N2 Stitch MCP — Resilient Proxy Skill

Never lose a screen generation again. The only Stitch MCP proxy with TCP drop recovery.

The Problem

Google Stitch's generate_screen_from_text takes 2–10 minutes, but the API drops TCP after ~60 seconds.

Other MCP servers:  Request → 60s → TCP drop → ❌ LOST!
N2 Stitch MCP:      Request → 60s → TCP drop → 🛡️ Auto-recovery → ✅ Delivered!

Why This One?

Feature	Others	N2 Stitch MCP
TCP Drop Recovery	❌	✅ Auto-polling
Generation Tracking	❌	✅ generation_status
Exponential Backoff	❌	✅ 3x retry + jitter
Auto Token Refresh	⚠️	✅ Background refresh
Test Suite	❌	✅ 35 tests

1. Authenticate (one-time)

# Option A: gcloud (recommended)
