# 2025-12-04: AI Service - Deprecation of SSE transport protocol

## Overview

Since the official deprecation of the SSE transport in the Model Context Protocol spec [details here](https://github.com/modelcontextprotocol/modelcontextprotocol/pull/665?ref=changelog.keboola.com), MCP clients have been moving away from SSE. Based on the official deprecation, we are deprecating the `sse` transport protocol in the AI Service as well.
