Install Maxy — AI for Productive People

AI Security Review

scanned 3mo ago · by lpm-firewall-ai

Source confirms an explicit installer that intentionally bypasses Claude permission checks and installs plugins, warranting a warning. It lacks install-time execution and no concrete exfiltration or remote-payload chain was confirmed.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

User runs the create-maxy-code CLI.

Impact

Installed Claude sessions for this product can execute tools without normal permission prompts; bundled plugins expand agent capabilities.

Mechanism

Brand-scoped Claude permission bypass plus plugin marketplace installation.

Decision evidence

public snapshot

AI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

dist/index.js is the executable bin and runs the installer on user invocation.
dist/index.js calls seedBypassPermissionsSettings before installing Claude plugins.
dist/permissions-seed.js writes defaultMode "bypassPermissions", explicitly skipping all permission checks.
dist/index.js deploys bundled payload and installs local/external plugins into its Claude config.
payload/server/server.js can use Cloudflare and Claude OAuth endpoints with stored credentials.

Evidence against

package.json has only prepublishOnly; no preinstall, install, or postinstall hook.
The Claude config target is brand-scoped ~/.maxy-code/.claude, not the default shared ~/.claude path.
The permission/config mutation is reached through the explicit create-maxy-code bin, not package import/install.
No source-confirmed credential exfiltration endpoint or remote downloaded-code execution was found.
