The official MCP Server for the Roark API

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The package is not shown to be malware, but it provides a real, high-impact code-execution capability to MCP callers and includes a credential-forwarding remote execution path. It should be warned on rather than blocked because the behavior is product-aligned and not automatically triggered at installation.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

An MCP client invokes the execute tool with code, or a consumer initializes the server without local execution options.

Impact

An untrusted MCP client or agent can perform actions permitted by the configured Roark credentials and may access worker-visible environment values.

Mechanism

Caller-controlled code execution with authenticated API and environment access.

Network endpoints1

api.stainless.com

Decision evidence

public snapshot

AI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The MCP server enables its code-execution tool by default.
The worker evaluates caller-supplied TypeScript and invokes the exported function.
Local execution grants the worker environment access and forwards the host environment plus client-provided variables.
The library-only remote mode sends the Roark bearer token and merged client environment data to api.stainless.com.

Evidence against

package.json has no preinstall, install, or postinstall lifecycle hook.
The normal CLI defaults to local Deno execution and scopes network access to the configured Roark API host.
No persistence, destructive filesystem action, or concealed payload was found.
