AI agents call list_all_components to retrieve information from MCP Modus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates available components from documentation without modifying, deleting, or executing anything. It has minimal blast radius—misuse would at worst return unwanted data that is already public documentation. Categorized as Read with low severity.
