Get notes from the user
AI agents call get_coach_notes to retrieve information from Arvo MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves user notes without side effects. It is a read-only query operation that does not create, modify, delete, or execute any actions. The fitness coach context confirms these are personal notes/data being retrieved for display or analysis purposes. Severity is low because note data is typically non-sensitive fitness metadata and the impact of unauthorized access is limited to information disclosure.
From the tool's definition Tool name and description indicate retrieval of existing data ('Get notes from the user') with no modification, deletion, or execution capability.
