Claude Code v2.1.239 21 Aug 2026

Cloud sessions can be told to withhold the legacy device shell tool, dark in this build

Useful1 Signal3

Cloud Sessions

Cloud sessions could withhold the older device shell tool, but no session on this build does.

The disallowed-tools request exists but the flag requesting it is compiled to false.

What

Cloud and teleport session creation can send a disallowed-tools list naming mcp__remote-devices__device_bash, the older tool for running shell commands on a paired device. The flag that requests it comes from a helper compiled to return false, so no session on this build withholds it.

Evidence

mcp__remote-devices__device_bash

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
