Anthropic can centrally switch off remote tool serving, and messages explain that plugins and hooks aren't sent to cloud sessions while it's off.
Anthropic can now centrally disable remote tool serving via a global "emergency switch." New user-facing messages explain that while it's off, a computer's plugins and hooks are not sent to cloud sessions, and normal operation resumes once it's back on. Corresponding state changes mark serving as muted or stopped with reason 'muted' rather than idle.
