CLAUDE_CODE_DISABLE_MEMORY_STREAM_LIST

Updated October 13, 2026 by Alex Sorokoletov

CLAUDE_CODE_DISABLE_MEMORY_STREAM_LIST is a Claude Code environment variable: Turns off the incremental metadata-streaming path inside multi-store memory sync. That path (gated by the new tengu_memory_stream_list, default on) calls a backend exportMetadata() to pull a store's entry list, tracks success/failure streaks, and backs off via a retryAfterMs timer on repeated failures. Added between v2.1.143 and v2.1.212 and still present in v2.1.294. It is not in the official reference.

Status	Present in v2.1.294

How to set it

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

export CLAUDE_CODE_DISABLE_MEMORY_STREAM_LIST=<value>
claude

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

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