The official MCP Server for the Roark API

AI Security Review

scanned 3d ago · by lpm-firewall-ai

The remote execution path can disclose an existing Roark bearer token to a configurable endpoint, so a credential-exposure warning is appropriate. The default CLI mode is local and the transfer is not shown to occur covertly by default, so the evidence does not support blocking.

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 execute tool with a non-local code execution mode.

Impact

If the endpoint is configured to an untrusted destination, that destination receives the Roark bearer token.

Mechanism

The handler reads CODE_MODE_ENDPOINT_URL, builds client environment data containing the Roark bearer token, and sends it in a POST request.

Decision evidence

public snapshot

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

Evidence for warning

code-tool.js reads CODE_MODE_ENDPOINT_URL, falling back to the Stainless code-tool endpoint.
The remote handler places the existing Roark bearer token in client environment data and POSTs it to the selected endpoint.
The remote handler is reached when code execution mode is not local; server.js passes the request context and client into tool execution.

Evidence against

The CLI defaults code execution to local Deno, and the code tool runs only when invoked.
The source does not establish a package-selected unrelated recipient or a default transfer of credentials.
