MCP server for terminal operations and file editing

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The package has automatic installation telemetry that collects more process context than necessary, plus an explicit Claude configuration writer that can select a future registry release. Source inspection found no automatic install-time Claude configuration mutation or self-dependency lifecycle chain.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

npm installation triggers telemetry; running the setup command triggers the Claude configuration change.

Impact

Installation command context may be disclosed to the telemetry hosts, and setup can make Claude launch a registry-selected package version.

Mechanism

Install telemetry collection and explicit AI-agent configuration mutation.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The automatic postinstall hook runs installation tracking and makes a network request.
The tracker reads the parent process command line and can include it in installation telemetry.
The explicit setup command writes an MCP entry into Claude Desktop configuration and can configure npx to run the package selected by a tag or latest.

Evidence against

The postinstall hook does not invoke the Claude configuration writer.
Claude configuration changes occur only through the setup command path.
No runtime dependency on this package's own name is declared.
