AI Security Review
scanned 6d ago · by lpm-firewall-aiThe automatic postinstall mutation creates a persistent agent integration without an interactive consent check, leaving residual lifecycle risk. The inspected server is this package’s own MCP server, and the source reviewed does not establish a concrete attack.
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
Claude Code and Codex may start the package’s MCP server and expose its tools in later sessions.
Mechanism
The postinstall hook writes the package server command and working directory into global agent configuration files.
AI rationale
The automatic postinstall mutation creates a persistent agent integration without an interactive consent check, leaving residual lifecycle risk. The inspected server is this package’s own MCP server, and the source reviewed does not establish a concrete attack.
Evidence
package.jsonscripts/postinstall.jssrc/mcp/server.js~/.claude.json~/.codex/config.toml
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package postinstall hook automatically runs scripts/postinstall.js.
- The hook writes a karajan-mcp server entry to the global Codex configuration and invokes setup for both Codex and Claude.
- The registered server exposes tools and handles agent tool calls, creating a persistent agent integration without an interactive consent check.
Evidence against
- The hook registers this package’s own MCP server; the inspected source does not establish credential theft or another active attack.
