+## 🤖 Extending with Cognitive Memory Systems
+
+The basic memory server provides entity storage, but production AI agents often need more sophisticated memory architectures. A **4-Tier Cognitive Memory System** extends this model:
+
+| Tier | Storage | Purpose | Speed |
+|------|---------|---------|-------|
+| **Working** | Redis / RAM | Ultra-fast ephemeral cache | ⚡⚡⚡ |
+| **Medium** | SQLite | Recent episodes & context | ⚡⚡ |
+| **Long-Term** | Vector DB | Persistent knowledge with embeddings | ⚡ |
+| **Deep** | Knowledge Graph (MCP Memory) | Complex semantic relationships | Slow |
+
+This layered approach allows AI agents to:
+- Maintain instant context (Working)
+- Remember recent conversations (Medium)  
+- Store persistent knowledge (Long-Term)
+- Build complex relationship understanding (Deep)
+
+Example integration pattern:
+```python
+# Cognitive Memory Bridge
+class CognitiveMemoryBridge:
+    async def store_interaction(self, user_id: str, content: str):
+        # 1. Working memory - instant cache
+        await redis.setex(f"session:{user_id}", content)
+        
+        # 2. Medium memory - recent context
+        await sqlite.execute("INSERT INTO medium_memory VALUES (?)", content)
+        # 3. Long-term - embed and vectorize
+        embedding = await embed(content)
+        await vector_db.insert(embedding)
+        # 4. Deep - create graph relations
+        await mcp_memory.create_entities([{"name": user_id, ...}])
+```
