@roarkanalytics/sdk-mcp@4.10.0

The official MCP Server for the Roark API

AI Security Review

scanned 24d ago · by lpm-firewall-ai

The package has an unresolved credential-forwarding risk because an existing service credential can be sent to an unrestricted configured endpoint. Static inspection found no install hook or separate evidence of malicious intent.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

An MCP execute-tool request while remote execution is selected.

Impact

A process operator who sets the endpoint variable can expose the active Roark credential to that endpoint; no confirmed covert attack was found.

Mechanism

The handler obtains the bearer token from the environment or client, merges it into client environment data, and POSTs that data to the configured endpoint.

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The package declares ordinary build and test scripts, with no install lifecycle hook.
The MCP server includes the code-execution tool by default and selects remote execution by default.
The remote endpoint is configurable through an environment variable while the Roark bearer token is taken from environment or the active client.
The request sends the merged client environment, including that bearer token, to the selected endpoint.

Evidence against

The built-in endpoint is a named Stainless service rather than an unrelated hidden host.
No install-time mutation, persistence, or destructive behavior was found.
