Install Maxy — AI for Productive People

AI Security Review

scanned 3mo ago · by lpm-firewall-ai

The package is high risk because its explicit CLI seeds a Claude permission-bypass configuration and persists a managed agent environment. It lacks install-time lifecycle execution, so the policy boundary calls for a warning rather than a block.

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 (for example via npx).

Impact

A user-invoked install can create an unattended, broadly permissioned Claude environment and persistent local services.

Mechanism

Explicit installer seeds bypass-permissions Claude config and installs agent plugins/services.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 95.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

dist/index.js runs a full privileged installer when the bin is invoked.
dist/permissions-seed.js writes Claude settings with defaultMode "bypassPermissions".
dist/index.js installs Claude plugins at user scope and registers remote marketplaces.
dist/index.js downloads/runs third-party installers and persists system services.

Evidence against

package.json has only prepublishOnly; no npm install/preinstall/postinstall hook.
Entrypoint behavior requires explicit execution of create-maxy-code.
Observed network targets are named infrastructure/package sources, not a covert exfiltration endpoint.
