# The HTTP+SSE transport is deprecated

Model Context Protocol deprecated transport sse without giving a shutdown date yet.

Model Context Protocol deprecated transport sse without a shutdown date. Calls relying on this transport will fail once the removal takes effect. This change specifically impacts implementations currently using transport sse.

## What to use instead

Connect over Streamable HTTP at the endpoint the server documents, usually /mcp. Switching requires a team decision beyond changing an identifier, as Streamable HTTP works only if the target server supports it.

Streamable HTTP works only where the server serves it too, which the calling code does not tell: the team decides.
