The official MCP Server for the Roark API

AI Security Review

scanned 3d ago · by lpm-firewall-ai

The package does not show a concrete malicious action or install-time behavior, but its default agent-invoked code runner exposes the parent process environment to submitted code. This warrants a warning for dangerous local code execution capability.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

A caller invokes the default execute tool with code that reads environment variables.

Impact

Submitted code could expose host environment values through available API operations or return them to the caller. No automatic installation-time execution or unrestricted network path was identified.

Mechanism

The Deno worker inherits the parent process environment and receives permission to read environment variables; its network access is restricted to the configured Roark API hostname.

AI rationale

Evidence

package.jsonserver.jsoptions.jscode-tool.jscode-tool-worker.js

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest points to index.js and contains no install, preinstall, or postinstall hook.
The server includes the execute tool by default, and the CLI defaults code execution to local mode.
The local worker receives submitted code and evaluates it with the authenticated SDK client.
The Deno worker receives the parent process environment and is granted environment access.
The worker's network permission is limited to the configured Roark API hostname.

Evidence against

Code execution requires an execute tool call with supplied code; no automatic execution at installation was identified.
The inspected local worker network grant is scoped to the configured API hostname.
