gdrive_export_sheet · Mcp Google Gdrive MCP: Risk & Policy

WHAT IT DOES

What gdrive_export_sheet does on Mcp Google Gdrive

AI agents use gdrive_export_sheet to create or update resources in Mcp Google Gdrive — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Google Gdrive environment.

WHY IT NEEDS A POLICY

Why gdrive_export_sheet needs a policy

While the tool reads from Google Sheets (a Read operation), the primary action is exporting and writing data to local disk storage, which is a reversible modification of the filesystem. This classifies as Write rather than Read. Severity is medium because unintended exports could exfiltrate sensitive spreadsheet data, but the action is reversible (exported files can be deleted).

From the tool's definition Tool exports Google Sheets to file formats (CSV, JSON, XLSX) and saves XLSX to disk (savePath parameter). The export and disk write operations constitute data creation/modification in the local filesystem.
