AI agents call fm_list_value_lists to retrieve information from FileMaker 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 metadata about dropdown/selection values configured on a FileMaker layout. It performs a query operation with no side effects, returning informational data only. The action is purely exploratory and non-destructive, fitting the Read category. Low severity because exposure of dropdown options carries minimal security risk compared to actual record data retrieval.
From the tool's definition Tool name 'fm_list_value_lists' and description indicate retrieval of value lists/dropdown options from a specified layout. The description states it 'gets' (取得します) available value lists and allows one to 'confirm' (確認できます) field dropdown choices.
