## 📝 Notes de Recherche

### Découvertes Clés

1. **Aucun MCP ne fait de génération C++**
   - Tous les MCP existants font du runtime control
   - Niche complètement ouverte

2. **Blueprint parsing bien établi**
   - Multiple libraries disponibles
   - uasset-reader-js parfait pour TypeScript
   - Dataset académique disponible (MSR 2025)

3. **Génération Blueprint possible**
   - Bluepy prouve que c'est faisable
   - Python API puissante
   - FKismetEditorUtilities bien documenté

4. **Round-trip techniquement faisable**
   - NodeToCode fait BP→C++
   - Bluepy fait description→BP
   - Notre innovation : combiner les deux

5. **Marché actif et demandeur**
   - 10+ projets MCP en développement actif
   - Forums pleins de demandes pour ces outils
   - Plugins commerciaux viables

### Gaps Identifiés

❌ **Pas de génération C++ production-ready**
❌ **Pas de workflow bidirectionnel**
❌ **Pas d'optimisation automatique**
❌ **Pas d'analyse statique Blueprint**
❌ **Pas de support multiplayer avancé**

✅ **Notre opportunité unique**
