bulk_add_rows · Smartsheet MCP Server MCP: Risk & Policy

WHAT IT DOES

What bulk_add_rows does on Smartsheet MCP Server

AI agents use bulk_add_rows to create or update resources in Smartsheet MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Smartsheet MCP Server environment.

WHY IT NEEDS A POLICY

Why bulk_add_rows needs a policy

This tool creates new rows in a Smartsheet, modifying data reversibly. While it doesn't delete or overwrite existing data (which would be Destructive), it creates multiple records in a single call. The 'high' severity reflects that an AI agent could rapidly populate sheets with incorrect or malicious data, potentially affecting workflows dependent on that sheet.

From the tool's definition Tool name 'bulk_add_rows' and description 'Adds multiple rows to a sheet in a single operation' explicitly indicate creation of data. The 'bulk' aspect amplifies impact by allowing batch modification.
