Fix Claude Code appearing logged-out over SSH on a headless macOS machine — its credentials sit in the login keychain, which stays locked in SSH/headless sessions. Offers two fixes and asks the user to choose: a keychain-free long-lived setup-token, or auto-unlocking the login keychain with a stored password (required on any machine in a cux-rotated fleet, where a setup-token cannot be registered or measured). Use when Claude Code shows unauthenticated over SSH on a Mac, when setting up a Mac…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Claude Code auth on a headless Mac over SSH ## Problem Claude Code (subscription / OAuth login) stores its credentials in the macOS **login keychain**, encrypted with the user's macOS login password. A GUI login unlocks it automatically; an SSH / headless session does **not**, so Claude Code looks logged out until the keychain is unlocked. Two facts shape the fix: - `sudo` cannot help — unlocking is *decryption*, and root has privilege but not the password. - On macOS the keychain is the credential's *intended* home; `~/.claude/.credentials.json` is not the supported Linux-style alternative you can simply opt into. **But do not read that second point as "the file never exists on macOS."** It does, and mistaking its presence for a healthy configuration wastes hours. `cswap` degrades to writing `~/.claude/.credentials.json` whenever the keychain is unavailable mid-operation, so a full OAuth credential — `refreshToken` present, complete scopes — can end up living there on a Mac. Observed 2026-08-19: the file was present (mode 600) on both headless fleet receivers and **absent** on the GUI machine, exactly tracking which ones had a locked keychain. …

How to install
mdr add soulmachine/skills/ssh-claude-auth@sha256:e75bab13bee5d75cThe line at the top of this page pins the label git:20260819.64f3b16, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
