Get Google Drive storage quota information
AI agents call get_storage_quota to retrieve information from Enhanced MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool merely queries and returns storage quota information from Google Drive. It performs no mutations, executes no external code, and has no destructive effects. The blast radius of misuse is minimal—an agent might retrieve quota data it shouldn't see, but cannot alter drive contents, execute operations, or cause irreversible harm. Classified as Read with low severity.
From the tool's definition Tool name 'get_storage_quota' and description 'Get Google Drive storage quota information' indicate a read-only query operation that retrieves quota metadata without modifying, executing code, or affecting resources.
