gdrive_create_file · Mcp Google Gdrive MCP: Risk & Policy

WHAT IT DOES

What gdrive_create_file does on Mcp Google Gdrive

AI agents use gdrive_create_file 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_create_file needs a policy

This tool creates new files, a write operation that modifies Google Drive state. While reversible (files can be deleted), it allows an AI agent to create arbitrary files in a user's Google Drive without explicit per-operation confirmation, potentially cluttering the drive or creating misleading documents. Severity is medium rather than high because the operation is reversible and does not delete data or move money.

From the tool's definition Tool description explicitly states 'Create a new file in Google Drive', which is a reversible write operation. Server description confirms it 'create[s]...files in Google Drive'.
