CLAUDE_GATEWAY_LOG_LEVEL

Updated October 14, 2026 by Alex Sorokoletov

CLAUDE_GATEWAY_LOG_LEVEL is a Claude Code environment variable. Removed between v2.1.269 and v2.1.283, so current releases ignore it. It is not in the official reference.

How to set it

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

export CLAUDE_GATEWAY_LOG_LEVEL=<value>
claude

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

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