WHAT IT DOES

What dataverse_list_tables does on Dataverse MCP Server

AI agents call dataverse_list_tables to retrieve information from Dataverse MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why dataverse_list_tables is rated Low

This tool retrieves metadata about available tables without creating, modifying, deleting, or executing operations. It is a pure read operation with minimal blast radius—listing tables provides information but does not alter system state. Severity is low because unauthorized listing of table names presents an information disclosure risk but is not immediately actionable for data compromise without additional tools.

From the tool's definition Tool name 'dataverse_list_tables' and description 'List all available tables in the Dataverse environment' indicate a retrieval operation with no side effects.
