cursor-account-switcher

What it is

cursor-switch is a small Go command-line tool, with an interactive terminal menu, that keeps saved sign-in sessions for several AI coding tools and swaps between them. It started with Cursor and now covers four platforms:

Platform	Where the session lives	Restarts the app
Cursor	state.vscdb	yes
Claude Code	~/.claude/.credentials.json and the Keychain	no
Codex	~/.codex/auth.json	no
VS Code / GitHub Copilot	state.vscdb and the Keychain	yes

The problem it solves

If you have a personal and a work subscription for the same tool, switching means signing out, signing in, and often a browser round-trip — every time. The session is just data on disk and in the Keychain, so the tool saves that data per account and puts it back.

How a switch works

1. The current session is saved back to its profile first, so refreshed tokens aren't lost.
2. For editors that hold the session in memory (Cursor, VS Code), the app is force-quit and the tool waits until it has actually exited.
3. The target profile is restored: the cursorAuth/* keys in Cursor's SQLite state database, the GitHub keys and Keychain item for VS Code, the claudeAiOauth tokens and oauthAccount metadata for Claude Code, or auth.json for Codex.
4. The editor is started again where needed.

For Claude Code, the Keychain write merges tokens into the existing item instead of replacing it, so MCP plugin authentication stored there survives.

Usage

cursor-switch                        # interactive menu
cursor-switch platform use claude    # choose the default platform
cursor-switch save personal          # save the current session
cursor-switch switch work            # by id or label
cursor-switch --platform codex save work

Accounts default to personal and work; add more with labels. Each platform keeps its own account list.

Limits

• Codex must use file-based auth; keyring-only mode isn't supported yet.
• Copilot sometimes needs one sign-out/sign-in after a switch to pick up the new session.
• Profiles contain live auth tokens. They are written with 0600 permissions under ~/.cursor-account-switcher/, and should be kept private.

Stack

Go, Cobra, Bubble Tea / Lip Gloss, and a pure-Go SQLite driver. Installs to ~/.local/bin with a one-line script or make install.
