create_spreadsheet · Enhanced MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_spreadsheet does on Enhanced MCP Server

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

WHY IT NEEDS A POLICY

Why create_spreadsheet needs a policy

This tool creates new resources (spreadsheets) in Google's cloud infrastructure, which is a reversible Write operation. Severity is high because: (1) it consumes user quota/storage, (2) the created spreadsheet persists in the user's Drive, and (3) an agent could create many spreadsheets if misused, causing organizational clutter or resource exhaustion.

From the tool's definition Tool description explicitly states 'Create a new Google Spreadsheet' — a create operation that generates new data artifacts in Google Drive/Sheets. The ability to create multiple sheets/tabs extends the scope of data structure creation.
