List fact tables for a project version.
AI agents call df_list_fact_tables to retrieve information from DataForge Semantic 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 fact tables available in a DataForge project version. It performs a read-only query operation without modifying, executing, or deleting any data. The blast radius of misuse is minimal—an AI agent could only discover metadata about available fact tables, which is informational only.
From the tool's definition Tool name 'df_list_fact_tables' and description 'List fact tables for a project version' indicate a retrieval operation. The verb 'list' is a query operation with no side effects.
