CLAUDE_CODE_ENABLE_AUTO_MODE

Updated October 13, 2026 by Alex Sorokoletov

CLAUDE_CODE_ENABLE_AUTO_MODE is a Claude Code environment variable: The master switch. Redundant on Bedrock/Vertex/Foundry now that Auto mode is default-on, but still the toggle everywhere else. It gates everything below. Added between v2.1.143 and v2.1.212 and still present in v2.1.294. It is listed in the official reference.

How to set it

For one session, export it in the shell that starts Claude Code:

export CLAUDE_CODE_ENABLE_AUTO_MODE=<value>
claude

To apply it to every session, add it to the env object of a settings file:

// ~/.claude/settings.json
{
  "env": {
    "CLAUDE_CODE_ENABLE_AUTO_MODE": "<value>"
  }
}
