Claude Code Multi-Account Switcher

This project installs a local workaround for switching Claude Code OAuth accounts by keeping account snapshots in ~/.ClaudeCodeMultiAccounts.json and writing only the active account back into Claude's live files when switching.

Supported user-facing commands:

• cc-switch
• cc-switch <index>
• cc-sync-oauth
• ccs (short alias for cc-switch)
• ccso (short alias for cc-sync-oauth)
• /cc-switch
• /cc-sync-oauth

Supported environments:

• Windows (PowerShell/CMD/Git Bash)
• Ubuntu WSL
• Native macOS/Linux with Node.js
• Claude chat shell mode via !cc-switch and !cc-sync-oauth

Prerequisites:

• Node.js 18+
• Claude Code already installed and logged in at least once

Install:

Recommended (via npm):

npx claude-code-multi-accounts install

Manual (from source):

git clone https://github.com/Leuconoe/ClaudeCodeMultiAccounts.git
cd ClaudeCodeMultiAccounts
./install.cmd   # Windows
./install.sh    # macOS / Linux / WSL

What install does:

• copies the Node CLI into ~/.claude/multi-account-switch/bin
• installs cc-switch, cc-sync-oauth, ccs, and ccso wrapper commands
• keeps stored account snapshots in ~/.ClaudeCodeMultiAccounts.json
• adds an auth_success hook entry to ~/.claude/settings.json
• adds a SessionStart reminder hook to ~/.claude/settings.json
• if statusLine.command already exists, wraps it and prepends use !cc-switch / !ccs to the existing HUD output
• installs global Claude command wrappers in ~/.claude/commands
• creates backups under ~/.claude/backups/multi-account-switch-installer

Uninstall:

Recommended (via npm):

npx claude-code-multi-accounts uninstall

Manual (from source):

./uninstall.cmd   # Windows

./uninstall.sh    # macOS / Linux / WSL

Usage:

cc-switch
cc-switch 1
cc-sync-oauth
ccs
ccso

Example shell output:

$ cc-switch
--- Usage ---
5h used/reset: 22.0% / 2026. 4. 2. 2:00 PM
7d used/reset: 31.0% / 2026. 4. 7. 10:00 PM

Available Claude accounts:
* [0] Alex Example <[email protected]> - Example Workspace - Pro | 5H:22%(~2h 7min) | 7D:31% (5D 10h) | synced: just now
  [1] Taylor Example <[email protected]> - Example Workspace - Teams | 5H:?(unknown) | 7D:? (unknown) | synced: never
  [2] Jordan Example <[email protected]> - Example Workspace - Enterprise | 5H:42%(~1h 10min) | 7D:51% (4D 6h) | synced: 1d ago

Run cc-switch <index> to make one of these stored entries the active Claude account.

$ cc-switch 1
Switched active account to [1] Taylor Example <[email protected]> (Teams).

Stored account list:
  [0] Alex Example <[email protected]> - Example Workspace - Pro | 5H:22%(unknown) | 7D:31% (unknown) | synced: just now
* [1] Taylor Example <[email protected]> - Example Workspace - Teams | 5H:?(unknown) | 7D:? (unknown) | synced: never
  [2] Jordan Example <[email protected]> - Example Workspace - Enterprise | 5H:42%(unknown) | 7D:51% (unknown) | synced: 1d ago

Output columns:

• synced: When the account was last synced into the store
• 5H: Current or cached 5-hour usage percent and reset estimate
• 7D: Current or cached 7-day usage percent and reset estimate
• Top usage block: live 5h used/reset and 7d used/reset values fetched from Claude when available

Claude chat shell usage:

!cc-switch
!cc-switch 1
!cc-sync-oauth
!ccs
!ccso

Claude /command usage:

/cc-switch
/cc-switch 1
/cc-sync-oauth

/cc-switch currently still goes through Claude's command-processing path, so !cc-switch remains the primary deterministic execution path. The slash command is installed now so it can benefit from future improvements in Claude's command handling.

Claude startup reminder:

Claude Code Multi-Account Switcher is available.
Use !cc-switch or !ccs to list/switch accounts.
Use !cc-sync-oauth or !ccso to sync the active account into oauthList.

Platform notes:

• Windows installs cc-switch.cmd and cc-sync-oauth.cmd into ~/bin, plus Git Bash-friendly cc-switch and cc-sync-oauth wrappers in the same directory.
• Short aliases ccs and ccso are installed alongside the full command names.
• Native macOS/Linux installs commands into ~/.local/bin.
• WSL also uses the Unix shell wrappers.
• If a shell says command not found right after install, restart the shell or run hash -r once.

Behavior notes:

• The tool stores metadata and credential snapshots in ~/.ClaudeCodeMultiAccounts.json.
• cc-sync-oauth imports the current live account into that store.
• Switching writes only the active oauthAccount back into ~/.claude.json and the active credential snapshot back into ~/.claude/.credentials.json.
• It creates backups before writing live files or the store file.
• Stored account ordering is stable.
• If a stored displayName is already corrupted, output falls back to the email local part.
• The displayed plan type is a best-effort inference from the available account fields and credential snapshot.
• The reset: column shows rate limit countdown for the current account, or a 7-day window estimate for others.
• Usage info from the Claude API is shown before the account list when rate limited.

Warnings:

• This is a local workaround, not an official Claude plugin.
• It still mutates internal Claude live files when switching accounts, but it no longer uses ~/.claude.json as the primary multi-account store.
• Native macOS/Linux support is implemented, but still needs real-host validation beyond Windows/WSL testing.
• npm packaging is prepared, but npm registry publish still requires npm authentication.

After this:

• npm / npx release refresh for v0.2.5
• non-AI hook execution path for /cc-switch if Claude exposes a direct command hook in the future
• improve plan type detection beyond the current best-effort inference
