# 🛡️ 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 |
