 - The controller creates the session key Secret of each Gateway only when the Secret is missing, and no longer overwrites the key on reconcile, which could invalidate stateful MCP sessions. If the Secret cannot be created, the Gateway reports `Programmed: False` with the reason `DeploymentFailed`.
 - Stateful MCP requests with a session ID that the proxy cannot decode, such as after the session key changes, now return `404` instead of `400`, so clients start a new session.
 - MCP streamable HTTP `POST` requests can list `application/json` and `text/event-stream` in separate `Accept` header lines instead of one comma-separated value.
+- MCP responses now honor the `spec.traffic.timeouts.responseIdle` response idle timeout, which previously did not apply on MCP routes. A response, including an SSE stream, that sends no data for longer than the timeout is now ended.
