MCP over HTTP

MCP over HTTP is the remote transport variant where JSON-RPC messages are sent as HTTP POST requests and server-initiated messages are delivered via server-sent events on a persistent GET connection. This transport enables MCP servers to run as cloud services accessible from any network location, in contrast to the local-only stdio transport. HTTP transport is appropriate for multi-user deployments, hosted integrations, and cases where the server manages shared state across many client sessions simultaneously.
