@agentvox/host@0.1.36
AgentVox host daemon — runs on machines you want to control hands-free via the AgentVox voice app.
AI Security Review
scanned 19d ago · by lpm-firewall-aiSource inspection found a narrowly scoped postinstall permission fix and expected AgentVox and xAI network behavior. The flagged agent location only reads Claude session history; no concrete attack surface was established.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The postinstall hook runs during installation; network requests and host controls run when the user pairs or starts the AgentVox host or voice assistant.
Impact
No unauthorized credential forwarding, remote payload execution, or agent configuration mutation was established.
Mechanism
The install hook adjusts permissions on node-pty helper files. Runtime authentication uses the configured AgentVox proxy, and xAI credentials are sent to the xAI API.
AI rationale
Source inspection found a narrowly scoped postinstall permission fix and expected AgentVox and xAI network behavior. The flagged agent location only reads Claude session history; no concrete attack surface was established.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json runs a postinstall script that only adds execute permission to node-pty helper files.
- The flagged Claude path reads session-history directories; it does not configure or install an agent extension.
- The host sends its saved token to the configured proxy, while the xAI key is sent to xAI’s API endpoint.
- The update checker uses the npm registry and can be disabled with AGENTVOX_AUTO_UPDATE=0.
