Claude Code v2.1.246

Claude in Chrome is recognised as a first-party surface

Under the hood
Useful2 Signal3
MCP

The Claude in Chrome connection is now recognised as first-party by its tool-name prefix too.

What

Claude Code now identifies the Claude in Chrome connection by tool-name prefix as well as by server name, and treats it as first-party in the same check that already covered its other internal connections.

Details
  • The Chrome-specific classification floor still applies only when the chromeClassifierFloorEnabled switch is true.
Evidence

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