2025-12-05: ACI - Streamable HTTP
Overview
In order to maintain alignment with the Model Context Protocol (MCP) and to provide a more robust, future-proof integration experience, we are deprecating the SSE (Server-Sent Events) transport in the AI Service. MCP has officially deprecated SSE, and MCP clients are already moving away from it. In line with this, our MCP servers now support the Streamable HTTP Protocol instead, providing a modern, reliable and standards-compliant way to stream responses.
This change reduces long-term risk, simplifies integrations, and ensures that new capabilities can be delivered faster on top of a single, well-supported protocol.
