claude-multiacc@1.0.21

Multi-account addon for Claude Code and OpenAI Codex CLI: every claude / claude -p and every codex / codex exec runs under a randomly-picked subscription account with the most usage headroom. Mirrors to a deploy server. No API keys.

AI Security Review

scanned 15d ago · by lpm-firewall-ai

The install hook is limited to global installs and delegates to the package's setup script. Although the default sync target and portable-token transfer merit notice, the inspected sync code excludes machine-local OAuth credentials and no concrete malicious chain was established.

Static reason

One or more suspicious static signals were detected.

Trigger

A global npm install may trigger setup; account synchronization is invoked through the package's account-management commands.

Impact

No concrete malicious effect was established from the inspected source. Portable tokens may be transmitted to the configured sync server when synchronization is invoked.

Mechanism

The postinstall gates setup on global-install state. The sync code sends pool data and portable tokens to its target and excludes machine-local OAuth credential files.

Decision evidence

public snapshot

AI called this Clean at 84.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json runs the test suite through tests/run-tests.sh, whose inspected excerpt creates a fake Claude binary for tests.
Postinstall skips CI and local installs and runs setup only for a global install.
The sync implementation states that machine-local OAuth credential files are never pushed; it syncs portable tokens and pool data to its configured target.

Evidence against

The package defines a postinstall hook, and its postinstall can run install.sh for global installs.
The shared configuration defines a default remote server; sync can send portable account tokens there.

2// Runs after `npm install`. On a GLOBAL install/update it wires the addon up by

3// running install.sh (idempotent), so `npm i -g claude-multiacc@latest` fully updates

4// the shim, CLI, and scheduled jobs with no extra step. Deliberately best-effort:

5// npm's own CI, sandboxes, and non-global/dev installs must never be broken by it, and

6// a failed install.sh must not fail `npm install` — it only prints how to finish by hand.
