+## Comparaison de Taille de Payload
+
+### Mode Lightweight
+```json
+{
+  "id": "abc123",
+  "title": "Note avec images",
+  "content": "Début du contenu qui est automatiquement tronqué à 200 caractères pour réduire...",
+  "hasImages": true,
+  "imageCount": 3,
+  "color": "blue",
+  "type": "text",
+  "isPinned": false,
+  "isArchived": false
+}
+```
+**Taille :** ~300 bytes par note
+
+### Mode Full Details
+```json
+{
+  "id": "abc123",
+  "title": "Note avec images",
+  "content": "Contenu complet de la note qui peut être très long...",
+  "images": [
+    "data:image/png;base64,iVBORw0KGgoAAAANSUhEUg... (100KB+)",

+  ],
+  "checkItems": [...],
+  "labels": [...],
+  ...
+}
+```
+**Taille :** 450KB+ par note avec 3 images
+
+### Économie
+Pour 10 notes avec images :
+- **Lightweight :** ~3 KB
+- **Full Details :** ~4.5 MB
+- **Économie :** **99.93%** 🎉
+
+## Utilisation dans N8N
+
+### Workflow Tech News
+Le workflow utilise automatiquement le mode lightweight car :
+1. On ne fait que lire les titres des notes existantes
+2. On créé des notes texte sans images
+3. Pas besoin des détails complets
+
+### Configuration N8N
+```json
+{
+  "method": "POST",
+  "url": "http://localhost:3001/sse",
+  "body": {
+    "jsonrpc": "2.0",
+    "id": "{{ $now.toUnixInteger() }}",
+    "method": "tools/call",
+    "params": {
+      "name": "get_notes",
+      "arguments": {
+        "fullDetails": false  // ← Mode lightweight par défaut
+      }
+    }
+  }
+}
+```
+
+## Notes
+
+- Par défaut, `get_notes` retourne des données lightweight
+- Pour obtenir les images, spécifier `fullDetails: true`
+- Le contenu est tronqué à 200 caractères max
+- Utile pour :
+  - Lister les notes
+  - Rechercher par titre
+  - Vérifier l'existence d'une note
+  - Workflows N8N optimisés

+- Chercher les notes avec label "Tech News"
+- Notes en bleu avec icône 📰
+
+**Via MCP :**
+```bash

+  -d '{
+    "jsonrpc": "2.0",
+    "id": 1,
+    "method": "tools/call",
+    "params": {
+      "name": "get_notes",
+      "arguments": {
+        "search": "Tech News"
+      }
+    }
+  }'
+```
+
+## 🎯 Personnalisation
+
+### Changer la source RSS
+
+Dans le node "RSS Feed - Tech News" :
+```javascript
+// Remplacer l'URL par :
+"https://feeds.feedburner.com/venturebeat/SZYF"  // VentureBeat
+"https://www.wired.com/feed/rss"                 // Wired
+"https://techcrunch.com/feed/"                   // TechCrunch Alt
+```
+
+### Modifier les critères de sélection
+
+Dans le node "Prepare AI Analysis", modifier le prompt :
+```javascript
+Critères de sélection :
+- Focus sur [IA / Blockchain / Cloud / DevOps / ...]
+- Articles en français uniquement
+- Durée de lecture < 10 min
+- etc.
+```
+
+### Changer la fréquence
+
+Dans le node "Schedule - Every 6 hours" :
+- **Toutes les 3h** : `hoursInterval: 3`
+- **Tous les jours à 9h** : `cronExpression: "0 9 * * *"`
+- **Du lundi au vendredi** : `cronExpression: "0 9 * * 1-5"`
+
+### Modifier le nombre d'articles
+
+Dans "Prepare AI Analysis" :
+```javascript
+// Passer de 2 à 3 articles
+"sélectionnez les 3 articles les PLUS PERTINENTS"
+
+// Adapter la structure JSON
+{
+  "selected": [
+    { "index": 1, "reason": "..." },
+    { "index": 2, "reason": "..." },
+    { "index": 3, "reason": "..." }
+  ]
+}
+```
+
+### Changer la couleur/labels
+
+Dans le node "Format Note" :
+```javascript
+color: 'orange',  // ou red, green, purple, etc.
+labels: ['AI News', 'Breaking', 'Important']
+```
+
+## 🐛 Troubleshooting
+
+### Erreur "MCP Server not responding"
+```bash
+# Vérifier que le MCP server tourne
+curl http://localhost:3001/sse
+
+# Redémarrer si nécessaire
+cd d:\dev_new_pc\Keep\mcp-server
+node index-sse.js
+```
+
+### Erreur OpenAI "Rate limit exceeded"
+- Attendre quelques minutes
+- Réduire la fréquence du workflow
+- Upgrader votre plan OpenAI
+
+### Pas d'articles sélectionnés
+- Vérifier le flux RSS (URL valide ?)
+- Tester le prompt OpenAI manuellement
+- Vérifier les logs N8N
+
+### Notes non créées
+```javascript
+// Vérifier le payload MCP dans le node "MCP - Create Note"
+console.log($json);
+
+// Tester directement avec curl
+curl -X POST http://localhost:3001/sse \
+  -H "Content-Type: application/json" \
+  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"create_note","arguments":{"title":"Test","content":"Test"}}}'
+```
+
+## 📈 Optimisations Possibles
+
+1. **Multi-sources RSS**
+   - Ajouter plusieurs nodes RSS
+   - Merger les résultats
+   - Augmenter à 5-10 articles sélectionnés
+
+2. **Filtering avancé**
