@roarkanalytics/sdk-mcp@3.5.0
The official MCP Server for the Roark API
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has a concrete, default-path transfer of an API bearer token and arbitrary caller environment values to a third-party remote executor, plus unvalidated remote instruction loading. These are serious runtime risks but do not establish stealthy malware or an install-time attack chain.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
Starting the MCP server, or invoking its execute tool.
Impact
A third party receives credentials that can access the Roark API and can influence MCP instructions at runtime.
Mechanism
Remote instruction loading and credential forwarding to a remote code runner.
AI rationale
The package has a concrete, default-path transfer of an API bearer token and arbitrary caller environment values to a third-party remote executor, plus unvalidated remote instruction loading. These are serious runtime risks but do not establish stealthy malware or an install-time attack chain.

Decision evidence
public snapshotAI called this Suspicious at 93.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The default remote code tool sends the Roark bearer token and caller-supplied environment values to api.stainless.com.
- The MCP server fetches remote instructions at startup and supplies them to connected AI clients without validation.
- The package exposes code execution by default, increasing the impact of the remote credential transfer.
Evidence against
- package.json has no install or postinstall lifecycle hook.
- The network actions are part of named MCP documentation and code-execution tools; no persistence, destructive action, or hidden payload was found.
- The local execution path restricts network access to the configured Roark API host.
