Fields

io_modelcontextprotocol_server_info: Option<Implementation>

Identifies the server software producing the response. Servers SHOULD include this field on every response unless specifically configured not to do so. The {@link Implementation} schema requires name and version; other fields are optional. The value is self-reported by the server and is not verified by the protocol. It is intended for display, logging, and debugging. Clients SHOULD NOT use it to change their behavior, and SHOULD NOT rely on it for security decisions.

io_modelcontextprotocol_subscription_id: RequestId

Identifies the subscription stream this response closes, so the client can correlate it with the originating subscription — mirroring the same key on the stream’s notifications. The value is the JSON-RPC ID of the subscriptions/listen request that opened the stream (and equals this response’s id).
