Cause

Section titled “Cause”

cc-switch live projection is designed to write key connection, authentication, and model fields, plus provider-specific environment variables on the compatibility list. `CLAUDE_CODE_AUTO_MODE_SERVER` was added in Claude Code 2.1.281 and was not yet on that list, so it was not projected into `~/.claude/settings.json` even when configured in the provider env.

The maintainer fixed this in #7893 by adding the variable to `CLAUDE_EXCLUSIVE_ENV`. It is written when switching to the provider and removed when switching away if unchanged; a global value set by the user is unaffected.

Fix

Section titled “Fix”

  1. Update cc-switch to a version containing the #7893 fix. It treats `CLAUDE_CODE_AUTO_MODE_SERVER` from the provider env as a Claude-specific compatibility variable.

  2. Set `CLAUDE_CODE_AUTO_MODE_SERVER` to `0` in the provider env that accesses a third-party backend through cc-switch, then reapply that provider in the GUI.

  3. If you cannot update yet, run `export CLAUDE_CODE_AUTO_MODE_SERVER=0` in your shell rc to bypass settings.json rewriting.

FAQ

Section titled “FAQ”
How can I temporarily bypass settings.json rewriting?
Set `export CLAUDE_CODE_AUTO_MODE_SERVER=0` in your shell rc.
Why are other custom env keys preserved while only this variable is missing?
This key was not filtered specifically; at the time, it was not included in the Claude-specific compatibility variable list written by live projection.
