AI Security Review

scanned 7d ago · by lpm-firewall-ai

Source confirms unprompted, persistent first-party MCP registration by an install hook, which warrants a warning for agent extension lifecycle risk. The inspected behavior does not establish a concrete attack that supports blocking publication.

Static reason

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

Trigger

Installing the package with npm runs its postinstall hook.

Impact

The agent hosts can start the package's MCP server in future sessions without a separate setup action.

Mechanism

The hook adds or updates karajan-mcp entries in ~/.claude.json and ~/.codex/config.toml, configured to launch the local server.

AI rationale

Evidence

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

Decision evidence

public snapshot

AI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/postinstall.js automatically; its main routine invokes both agent registration functions.
The hook writes a karajan-mcp entry into the home Claude and Codex configurations that launches this package's local MCP server over stdio.
The other inspected integration targets concern separate scoped behavior, including an explicit kj-trash install command, project setup, checks, file filtering, and guideline destinations.

Evidence against

The registration points to this package's local server; the inspected hook does not show credential collection, network transfer, or unrelated permission grants.
The ai-trash hook installer is reached through an explicit install command that requires the --claude-code flag.
