By transport
Remote MCP servers: SSE
The earlier MCP transport for remote servers: the client opens a Server-Sent Events stream to receive messages and posts its own messages to a second URL the server names. The protocol has since moved to Streamable HTTP; many clients still accept SSE.

SSE was the remote transport of the first MCP specification revision (2024-11-05). Revision 2025-03-26 replaced it with Streamable HTTP and kept it only for backwards compatibility, so servers that still list an SSE endpoint often list a Streamable HTTP one too.
Connecting is the same as for any remote server: the assistant or client is given the URL, and signs in or sends the declared header if the server asks for one.
