Get detailed schema information for a specific table.
AI agents call mssql_describe_table to retrieve information from MSSQL Database 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 schema metadata (column definitions, types, constraints, etc.) from a table without modifying data, executing procedures, or triggering side effects. It is purely informational and read-only in nature. The server description confirms 'read-only operations by default,' supporting the Read classification.
