What
In cloud (CCR) remote sessions, Claude sees placeholder tools for connecting "Claude in Chrome", "Browser" and "Computer use". They now take an endsRelayOnCall option, and a fourth placeholder was added.
endsRelayOnCallis true for "Claude in Chrome", "Browser" and "Computer use". When the main agent calls one of them while a relay is active, Claude Code records a device-tool request, or a repeated request when automation tools are on and the call repeats.- A new tool,
request_computer, labelled "Your computer", does nothing when called. It is deferred and read-only and hasendsRelayOnCall: !1, so it records no request. - Its description says it cannot connect a computer, and that tools whose names start with
mcp__remote-devices__, if any, run on the user's computer. - A new result text tells Claude that the call did not connect a computer and no tool here can, to use
mcp__remote-devices__tools if present, and otherwise to carry on with its own tools and tell the user if the task needs their computer. That tool is enabled only in some sessions.
Why
Claude is steered toward remote-device tools, or to be honest with you, instead of claiming your computer is connected when nothing in the session can connect it. Calling a browser or computer placeholder can now end or hand off a relay.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what ending the relay means or whether anything besides the logging happens when these tools are called.
