--http (headless and GUI-hosted) and --serve --port answered anything that reached the loopback port, and the REST responses allowed every web origin. Loopback is shared by every process and user on the machine, so the port proved nothing. - Every REST request now needs Authorization: Bearer <token>, and every --serve --port request line a "token" field; otherwise 401 / unauthorized (the socket is closed). - The token is OCS_API_TOKEN when the launcher sets it, else 32 random bytes printed on stderr at startup; compared in constant time. - No CORS headers are sent, so a web page cannot read an answer. - stdio --serve and --mcp are unchanged (private to their parent / the GUI's own token).
