@agentvox/host@0.1.20
AgentVox host daemon — runs on machines you want to control hands-free via the AgentVox voice app.
AI Security Review
scanned 1mo ago · by lpm-firewall-aiInstall behavior is limited to making the node-pty helper executable, and agent-session reads plus xAI calls happen only when the user runs the daemon. Those primitives match the package's voice-control purpose and do not form a hidden install or exfiltration chain.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
User invocation of agentvox-host or agentvox-vox, not npm install.
Impact
No unconsented mutation of a foreign agent control surface, credential theft, or remote payload execution was established.
Mechanism
Postinstall only marks node-pty spawn-helper executable. Runtime code reads local agent session logs, launches configured CLIs, and talks to the configured AgentVox proxy and api.x.ai.
AI rationale
Install behavior is limited to making the node-pty helper executable, and agent-session reads plus xAI calls happen only when the user runs the daemon. Those primitives match the package's voice-control purpose and do not form a hidden install or exfiltration chain.
Decision evidence
public snapshotAI called this Clean at 86.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The only npm lifecycle hook is postinstall, which runs scripts/fix-pty-helper.mjs to chmod node-pty spawn-helper inside node_modules.
- dist/cli.js reads ~/.claude/projects and ~/.codex/sessions only after the user starts the host, to resume a working directory; it does not write Claude or Codex config during install.
- The voice client sends the caller-supplied XAI_API_KEY or ~/.agentvox/xai.key to https://api.x.ai for minting and chat, which is the key's intended service.
- Optional self-update runs only inside the started daemon, installs @agentvox/host from registry.npmjs.org, and can be turned off with AGENTVOX_AUTO_UPDATE=0.
Evidence against
- The running daemon can launch claude with bypassPermissions and codex with sandbox bypass, and it relays session snippets to the paired AgentVox proxy. Those actions are the documented hands-free product and are not install hooks.
- XAI_BASE_URL can point the same caller-supplied key at another OpenAI-compatible base URL; that is an explicit operator override of a configurable client.
