AI Security Review

scanned 3d ago · by lpm-firewall-ai

The manifest activates a postinstall hook that automatically edits global Claude and Codex configuration to register this package's MCP server. This supports a warning for agent extension lifecycle risk, but the inspected source does not establish a concrete malicious attack.

Static reason

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

Trigger

Installing the package with npm while Claude or Codex is configured or available.

Impact

The agents gain access to this package's MCP integration without an explicit setup choice during installation.

Mechanism

The hook writes or updates global agent configuration to launch the package's local MCP server.

AI rationale

Evidence

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

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package runs scripts/postinstall.js automatically after npm install.
The hook writes a Karajan MCP server entry into the user's Claude and Codex configuration without a consent check; the entry launches this package's local server.
Related agent configuration code is scoped to explicit setup or inspection, but that does not guard the separate automatic postinstall path.
The inspected source establishes automatic first-party agent extension setup, but does not establish credential transfer, private-content export, or another concrete attack.

Evidence against

The separate ai-trash hook installer requires an explicit install command with --claude-code.
The inspected fixture hook writes only into a temporary fixture directory.
