@roarkanalytics/sdk-mcp@4.6.0
The official MCP Server for the Roark API
AI Security Review
scanned 27d ago · by lpm-firewall-aiThe unrestricted endpoint override combined with forwarding an existing service credential is a concrete conditional credential-exposure capability. Static inspection found no install-time behavior, hidden recipient, or confirmed active theft.
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 enabled code-execution tool in remote mode.
Impact
An operator-configured endpoint could receive the Roark credential during code execution; no confirmed hostile recipient is present in the package.
Mechanism
The handler combines the existing Roark credential with client environment values and posts them to the configured code endpoint without a destination allowlist.
AI rationale
The unrestricted endpoint override combined with forwarding an existing service credential is a concrete conditional credential-exposure capability. Static inspection found no install-time behavior, hidden recipient, or confirmed active theft.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The code tool takes the Roark bearer token from the client or environment and selects its remote endpoint from an unrestricted environment variable.
- The remote handler sends the merged client environment values in a request header to that selected endpoint.
- The code tool is enabled by default when server tools are selected.
- The package metadata has no npm install lifecycle hook.
Evidence against
- The built-in fallback endpoint is a named Stainless API endpoint rather than an unrelated host.
- The credential forwarding occurs only when the MCP code-execution tool is invoked.
