AI agents call list_properties to retrieve information from Google Apps Script MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and displays script properties without modifying them, placing it in the Read category. Severity is medium rather than low because script properties in Google Apps Script often contain sensitive configuration data, API keys, or credentials that could aid further attack planning if exposed to an unauthorized agent, even though the tool itself performs no destructive or executable actions.
From the tool's definition Tool name 'list_properties' and description indicating it lists/displays (一覧表示) all script properties. This is a retrieval operation with no modification.
