-The following diagram illustrates the MCP architecture:

-| Component      | Description                                                                                     |
-|----------------|-------------------------------------------------------------------------------------------------|
-| **MCP hosts**  | LLM applications such as chat apps or AI assistants in your IDEs (like GitHub Copilot in Visual Studio Code) that need to access external capabilities |
-| **MCP clients**| Protocol clients, inside the host application, that maintain 1:1 connections with servers        |
-| **MCP servers**| Lightweight programs that each expose specific capabilities and provide context, tools, and prompts to clients |
-| **MCP protocol**| Transport layer in the middle        |
-
 MCP follows a client-server architecture where a host application can connect to multiple servers. Whenever your MCP host or client needs a tool, it connects to the MCP server. The MCP server then connects to, for example, a database or an API. MCP hosts and servers connect with each other through the MCP protocol.
 
-### Remote versus local MCP servers
-
-MCP utilizes a client-host-server architecture built on [JSON-RPC 2.0 for messaging](https://modelcontextprotocol.io/docs/concepts/architecture). Communication between clients and servers occurs over defined transport layers, and supports primarily two modes of operation:

 * **Remote MCP servers** - MCP clients connect to MCP servers over the internet, establishing a connection using HTTP and server-sent events (SSE), and authorizing the MCP client access to resources on the user's account using OAuth.

 > * Because of the distributed nature of the API Management architecture, circuit breaker tripping rules are approximate. Different instances of the gateway do not synchronize and will apply circuit breaker rules based on the information on the same instance.
 > * Currently, only one rule can be configured for a backend circuit breaker.
 
+> [!CAUTION]
+> If you configure an Azure OpenAI service as a backend and the service receives too many requests, it returns a `429 Too Many Requests` response status code and  a `Retry-After` header with a value that can be large (for example, 1 day). With Azure OpenAI backends we recommend implementing circuit breaker rules to handle the `429` responses and accept the `Retry-After` duration.

 ### Example
 
 Use the Azure portal, API Management [REST API](/rest/api/apimanagement/backend), or a Bicep or ARM template to configure a circuit breaker in a backend. In the following example, the circuit breaker in *myBackend* in the API Management instance *myAPIM* trips when there are three or more `5xx` status codes indicating server errors in 1 hour.
