+#### Message Dispatch Options
+
+By default, the SSE server uses an in-memory message dispatch system for incoming POST messages. For production deployments or distributed scenarios, you can use Redis or implement your own message dispatch system that conforms to the `MessageDispatch` protocol:
+
+```python
+# Using the built-in Redis message dispatch
+from mcp.server.fastmcp import FastMCP
+from mcp.server.message_queue import RedisMessageDispatch
+
+# Create a Redis message dispatch
+redis_dispatch = RedisMessageDispatch(
+    redis_url="redis://localhost:6379/0", prefix="mcp:pubsub:"
+)
+
+# Pass the message dispatch instance to the server
+mcp = FastMCP("My App", message_queue=redis_dispatch)
+```
+
+To use Redis, add the Redis dependency:
+
+```bash
+uv add "mcp[redis]"
+```
+
