Auto mode is unavailable — the server returned no safety verdict

Auto mode’s safety check got no answer for ten responses in a row, so Claude Code stopped instead of acting unchecked.

Message

The exact error

Claude Code
Auto mode is unavailable — the server returned no safety verdict for the last 10 responses, so Claude stopped. Send a message to try again, or switch out of auto mode.

Also appears as:

For a single action
The server-side auto mode classifier gave no verdict (timed out), so auto mode cannot determine the safety of <tool>.

Meaning

What it means

In auto mode, a classifier on Anthropic’s side reviews each action before Claude Code runs it. When the server gives no verdict, the action is denied. After ten responses in a row without a verdict, Claude Code stops the turn rather than keep trying blind. It’s a safety stop, not a crash.

Causes

Common causes

  • A temporary problem with the server-side classifier
  • An LLM gateway or proxy that cuts short or rewrites streaming responses, dropping the verdict

Fix

How to fix it

  1. Send another message

    Claude tries again and the count starts over.

  2. If you use a gateway or proxy

    Check that it passes streaming responses through unchanged; see Anthropic’s gateway compatibility guidance.

  3. Use Claude Code’s own classifier requests

    Set CLAUDE_CODE_AUTO_MODE_SERVER=0 before starting Claude Code.

    macOS / Linux
    export CLAUDE_CODE_AUTO_MODE_SERVER=0
    claude
    Windows PowerShell
    $env:CLAUDE_CODE_AUTO_MODE_SERVER = '0'
    claude
  4. Approve actions yourself

    Switch out of auto mode so Claude Code asks before each action.
