Subject: [PATCH] MCP server: add Streamable-HTTP transport (--http)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The transport every web UI (Open WebUI, LibreChat, AnythingLLM, Jan, LobeChat)
consumes natively — so the brain plugs into browser UIs, not just stdio clients.
Atlas Corporation proprietary.
