問題文

A client wants the server to emit log messages while a specific tool call runs. How is the log level requested in the 2026-07-28 revision?

選択肢

1. By opening a subscriptions/listen stream with a logging filter.
2. By sending a logging/setLevel request once, after which the server applies that level to every subsequent request on the connection until the client changes it again, which keeps the per-request metadata smaller for clients that always want the same verbosity.
3. By including the logLevel key in that request's _meta; the server must not emit notifications/message for requests that omit it.
4. The server always emits logs and the client filters them.
