WHAT IT DOES

What explain_table does on Mcp Windows

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

RISK

Why explain_table is rated Low

This tool performs a read-only operation that queries and returns information about database table structure. It has no side effects, cannot modify data, and poses minimal risk even if misused by an AI agent. The severity is low because it only exposes non-sensitive schema metadata that would typically be available to any database user with basic access.

From the tool's definition Tool description states 'Explain table structure (alias for DESCRIBE)' - DESCRIBE is a SQL query command that retrieves metadata about table schemas without modifying data.

explain_table Allowed

explain_table is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
