List all tables in a database
AI agents call mssql_list_tables to retrieve information from Enhanced MCP MSSQL Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries database metadata to enumerate table names, a typical Read operation. It has no side effects, cannot modify data, and returns structural information only. The blast radius of misuse is minimal—an agent could map database structure but cannot access or alter data. Confidence is high given the explicit read-only design and the self-explanatory functionality.
From the tool's definition Tool name 'mssql_list_tables' and description 'List all tables in a database' indicate a schema discovery operation with no data retrieval or modification. Server description emphasizes 'read-only access' and 'schema discovery'.
