AI Security Review

scanned 12d ago · by lpm-firewall-ai

The package performs automatic agent configuration during npm installation, which warrants a warning under the agent extension lifecycle policy. The inspected code supports a package-owned MCP setup risk, not a confirmed attack.

Static reason

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

Trigger

Installing the npm package.

Impact

The agents may load this package’s MCP server in later sessions; the inspected behavior does not establish malicious server behavior.

Mechanism

The postinstall handler reads and rewrites the user’s Claude configuration and writes a Codex MCP configuration entry that launches this package’s 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

The package manifest runs scripts/postinstall.js during installation.
The postinstall handler registers the package’s MCP server in Claude Code and Codex configuration without a consent check.
The handler writes the Codex configuration and points both agent configurations at this package’s MCP server.

Evidence against

The configured MCP server is supplied by this package; the inspected code does not establish credential theft, remote payload execution, or another concrete attack.
