Get detailed information about a table structure
AI agents call sqlserver_describe_table to retrieve information from Multi-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 performs a schema inspection operation, retrieving structural metadata about a table (columns, types, constraints, etc.). It has no side effects and does not create, modify, delete, or execute code. It is a straightforward informational read operation with minimal security risk even if misused by an agent.
