HTTP / SSE transport

Definition

HTTP (streamable) and SSE transports run an MCP server as a hosted endpoint you connect to over the network via a URL.

These are the 'remote' transports — roughly 10% of servers. You point your client at a URL instead of launching a local process. They're the honest fix for sharing a server across a team or offloading heavy infrastructure, at the cost of trusting a third party with whatever passes through. Claude Desktop has no native remote transport and bridges these through the mcp-remote proxy.
