Microsoft Excel

Security checks across malware telemetry and agentic risk

Overview

This is a real Excel integration, but it can change or delete spreadsheet data without clear confirmation safeguards.

Install only if you trust Membrane and are comfortable granting Microsoft Excel access. Prefer a least-privileged Microsoft account or test workbook, review OAuth scopes during connection, and require explicit confirmation before any update, clear, delete, or raw proxy request.

Missing User Warnings

Medium

Confidence: 91% confidence
Finding: The skill advertises destructive actions such as deleting worksheets, tables, rows, and clearing ranges without any warning, confirmation, or guidance to verify scope before execution. In an agent setting, this increases the chance of accidental data loss or irreversible modification when the model selects an action from the documented capabilities.
