AI Security Review

scanned 5d ago · by lpm-firewall-ai

The manifest activates a postinstall hook that mutates Claude and Codex agent configuration to register this package's MCP server without an affirmative setup step. This is a first-party agent extension lifecycle risk, but the inspected source does not establish a separate concrete attack.

Static reason

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

Trigger

Installing the package with lifecycle scripts enabled.

Impact

The agents may load the package's MCP server in later sessions; the inspected setup does not establish credential theft or remote execution.

Mechanism

The postinstall hook writes the package's server registration to the user's Claude and Codex configuration files without an affirmative setup prompt.

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 the postinstall script during installation.
The postinstall script automatically registers the package's MCP server in Claude and Codex configuration and writes those configuration files without an affirmative setup step.

Evidence against

The registered server points to this package's own local MCP server; the inspected setup does not establish credential transfer or remote code execution.
