@roarkanalytics/sdk-mcp@3.26.0
The official MCP Server for the Roark API
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe source does not establish stealth malware or install-hook abuse, but it exposes code execution and forwards credentials to an external service when that handler is used. This warrants a warning for dangerous MCP capability rather than a publish block.
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
An MCP client invokes the execute tool, or a host uses the programmatic default tool selection.
Impact
A compromised or untrusted MCP client can cause execution and expose API credentials or supplied environment values to the remote service.
Mechanism
Dynamic code execution with credential forwarding to a remote sandbox endpoint.
AI rationale
The source does not establish stealth malware or install-hook abuse, but it exposes code execution and forwards credentials to an external service when that handler is used. This warrants a warning for dangerous MCP capability rather than a publish block.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The remote code tool forwards the Roark bearer token and caller-supplied environment values to api.stainless.com.
- The default MCP tool set exposes an execute tool, and its local mode starts Deno with environment access before dynamically importing supplied code.
- The package contains no install lifecycle hook, but this is a high-impact runtime capability for an MCP server.
Evidence against
- The npm manifest has no preinstall, install, or postinstall hook.
- The CLI defaults to local execution and restricts Deno network access to the configured API host and worker socket.
- No hidden persistence, destructive file operation, or unrelated network receiver was found in the inspected source.
