Authentication

Kurahi supports OAuth and API keys for model providers. Each provider supports the authentication methods listed on its provider page. For Anthropic: an API key, or the long‑lived token created by claude setup-token.

See /concepts/oauth for the full OAuth flow and storage layout.

Anthropic: API key

If you’re using Anthropic directly, use an API key.

1. Create an API key in the Anthropic Console.
2. Put it on the gateway host (the machine running kurahi gateway).

export ANTHROPIC_API_KEY="..."
kurahi models status

3. If the Gateway runs under systemd/launchd, prefer putting the key in ~/.kolo/.env so the daemon can read it:

cat >> ~/.kolo/.env <<'EOF'
ANTHROPIC_API_KEY=...
EOF

Then restart the daemon (or restart your Gateway process) and re-check:

kurahi models status
kurahi doctor

If you’d rather not manage env vars yourself, the onboarding wizard can store API keys for daemon use: kurahi onboard.

See Help for details on env inheritance (env.shellEnv, ~/.kolo/.env, systemd/launchd).

Anthropic: setup-token (subscription auth)

If you use a Claude subscription, run the setup-token flow on the gateway host:

claude setup-token

Then paste it into Kurahi:

kurahi models auth setup-token --provider anthropic

If the token was created on another machine, paste it manually:

kurahi models auth paste-token --provider anthropic

If you see an Anthropic error like:

This credential is only authorized for use with Claude Code and cannot be used for other API requests.

…use an Anthropic API key instead.

Manual token entry (any provider; writes auth-profiles.json + updates config):

kurahi models auth paste-token --provider anthropic
kurahi models auth paste-token --provider openrouter

Automation-friendly check (exit 1 when expired/missing, 2 when expiring):

kurahi models status --check

Optional ops scripts (systemd/Termux) are documented here: /automation/auth-monitoring

claude setup-token requires an interactive TTY.

Checking model auth status

kurahi models status
kurahi doctor

Controlling which credential is used

Per-session (chat command)

Use /model <alias-or-id>@<profileId> to pin a specific provider credential for the current session (example profile ids: anthropic:default, anthropic:work).

Use /model (or /model list) for a compact picker; use /model status for the full view (candidates + next auth profile, plus provider endpoint details when configured).

Per-agent (CLI override)

Set an explicit auth profile order override for an agent (stored in that agent’s auth-profiles.json):

kurahi models auth order get --provider anthropic
kurahi models auth order set --provider anthropic anthropic:default
kurahi models auth order clear --provider anthropic

Use --agent <id> to target a specific agent; omit it to use the configured default agent.

Troubleshooting

“No credentials found”

If the Anthropic token profile is missing, run claude setup-token on the gateway host, then re-check:

kurahi models status

Token expiring/expired

Run kurahi models status to confirm which profile is expiring. If the profile is missing, rerun claude setup-token and paste the token again.

Requirements

• Claude Max or Pro subscription (for claude setup-token)
• Claude Code CLI installed (claude command available)
