What
Some MCP servers, connections that give Claude extra tools, need you to sign in. A tool lets Claude finish that sign-in from the callback link (the address the browser lands on afterwards). It used to run without asking. Now:
When prompts are avoided, as in dontAsk mode, or the session is not interactive, a pasted link is refused and you are told to run /mcp in the session's terminal and sign in there.
Otherwise Claude Code asks for permission, with No as the default and no option to always allow it.
The check that the link matches the sign-in that was started now happens before the tool runs.
The tool is controlled by a setting Claude Code receives from its server.
Why
Claude can no longer quietly finish a sign-in using a link it was given in the conversation.
Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
