+## Set Max Request / Response Size on LiteLLM Proxy
+
+Use this if you want to set a maximum request / response size for your proxy server. If a request size is above the size it gets rejected + slack alert triggered
+
+#### Usage 
+**Step 1.** Set `max_request_size_mb` and `max_response_size_mb`
+
+For this example we set a very low limit on `max_request_size_mb` and expect it to get rejected 
+
+:::info
+In production we recommend setting a `max_request_size_mb` /  `max_response_size_mb` around `32 MB`
+
+:::
+
+```yaml
+model_list:
+  - model_name: fake-openai-endpoint
+    litellm_params:
+      model: openai/fake
+      api_key: fake-key
+      api_base: https://exampleopenaiendpoint-production.up.railway.app/
+general_settings: 
+  master_key: sk-1234
+
+  # Security controls
+  max_request_size_mb: 0.000000001 # 👈 Key Change - Max Request Size in MB. Set this very low for testing 
+  max_response_size_mb: 100 # 👈 Key Change - Max Response Size in MB
+```
+
+**Step 2.** Test it with `/chat/completions` request
+
+```shell
+curl http://localhost:4000/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer sk-1234" \
+  -d '{
+    "model": "fake-openai-endpoint",
+    "messages": [
+      {"role": "user", "content": "Hello, Claude!"}
+    ]
+  }'
+```
+
+**Expected Response from request**
+We expect this to fail since the request size is over `max_request_size_mb`
+```shell
+{"error":{"message":"Request size is too large. Request size is 0.0001125335693359375 MB. Max size is 1e-09 MB","type":"bad_request_error","param":"content-length","code":400}}
+```
