 ### MCP architecture

-The architecture consists of the following components:

-| **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.
