CLAUDE_RUNNER_FETCH_SERVER_PROGRESS_CAP_MS

Updated October 14, 2026 by Alex Sorokoletov

CLAUDE_RUNNER_FETCH_SERVER_PROGRESS_CAP_MS is a Claude Code environment variable: On a self-hosted runner, caps how long a git fetch keeps waiting while the server is still reporting progress on a large repository. Takes milliseconds, clamped between a two-minute floor and a thirty-minute ceiling; 0 or off removes the cap. Default is ten minutes. Named in the v2.1.295 release notes.[1]. Added in v2.1.295 and still present in v2.1.296. 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_RUNNER_FETCH_SERVER_PROGRESS_CAP_MS=<value>
claude

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

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