CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST

Updated October 13, 2026 by Alex Sorokoletov

CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST is a Claude Code environment variable: Indicates that the API provider configuration is managed by the host application rather than by Claude Code itself. Added between v2.1.79 and v2.1.83 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_PROVIDER_MANAGED_BY_HOST=<value>
claude

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

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