DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.228

Gateway runs without an OIDC block, and names two more upstream failures

Useful3 Signal3
Gateway Notable not in their notes

You can run claude gateway without any OIDC config; sign-in endpoints simply return 404.

claude gateway
What

claude gateway no longer requires OIDC configuration. With it absent, the device authorization endpoints return 404 "not found", discovery advertises no supported grant types, and the Google groups warning is suppressed. Upstream errors 413 and 501 now get readable messages.

Details
  • Affected endpoints: GET /device, POST /device, and /oauth/device_authorization.
  • Discovery reports grant_types_supported: [] when OIDC is not configured.
  • 413 reads "request too large for this upstream"; 501 reads "upstream does not support this endpoint".
Evidence

upstream does not support this endpoint

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
