karajan-code@4.52.0

Local multi-agent coding orchestrator with TDD, SonarQube, and code review pipeline

AI Security Review

scanned 7d ago · by lpm-firewall-ai

The automatic global agent configuration change is a real lifecycle risk, but the inspected behavior registers the package's own server and does not establish a concrete attack. A warning is appropriate.

Static reason

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

Trigger

Installing the package through npm.

Impact

Future agent sessions may start this package's local MCP server. The inspected setup does not establish credential disclosure or remote execution.

Mechanism

The postinstall script writes a karajan-mcp server entry to the user's Claude Code and Codex configuration files without asking for consent.

AI rationale

Evidence

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

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/postinstall.js automatically during installation.
The postinstall routine registers this package's local MCP server in Claude Code and Codex configuration, then writes those configurations without a consent prompt.
The automatic registration adds the package's own server; the inspected setup does not show a remote recipient or credential transfer.
A separate ai-trash hook installer requires an explicit install command with --claude-code.
Other flagged agent-related code is scoped to project files, read-only configuration checks, or MCP inventory.

Evidence against

The automatic global configuration change is first-party package setup, rather than evidence of a separate payload or credential-exfiltration behavior.
