Overview

This appears to be a real GreytHR integration, but it gives an agent broad authenticated access to sensitive HR and payroll data without enough guardrails.

Install only if you trust Membrane and intend to let an agent access GreytHR. Use a least-privileged GreytHR account, prefer prebuilt Membrane actions, require explicit approval before any create/update/delete request, avoid exposing unnecessary employee or payroll fields, and revoke the connection when it is no longer needed.

Missing User Warnings

Medium

• Confidence: 90% confidence
• Finding: The skill explicitly documents arbitrary proxy requests to the GreytHR API, including support for mutating HTTP methods and raw request bodies, but does not require confirmation, scope restrictions, or safety checks. In an HR/payroll context, this can expose or modify sensitive employee, attendance, leave, and payroll data, making unintended destructive or privacy-impacting actions more likely.
