AI Security Review

scanned 9d ago · by lpm-firewall-ai

The automatic postinstall configuration change is a first-party MCP integration, which warrants a warning under the agent extension lifecycle policy. Inspected source shows no confirmed malicious behavior in this setup path.

Static reason

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

Trigger

Installing the npm package runs its postinstall hook.

Impact

This changes global agent configuration without an install-time prompt. The source supports a warning for first-party package-owned agent setup, not a confirmed malicious attack.

Mechanism

The hook writes a Claude MCP entry and adds a marked Codex MCP block that launch this package's local server.

AI rationale

Evidence

package.jsonscripts/postinstall.js~/.claude.json~/.codex/config.toml

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/postinstall.js as an npm postinstall hook.
The hook calls both agent-registration functions without an install-time prompt.
The Claude entry points to this package's local MCP server and is written to the user's Claude config.
The Codex config receives a marked MCP server entry pointing to this package's local server.
