describe_table

What describe_table does on Mcp Windows

AI agents call describe_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.

Why describe_table is rated Low

This tool queries and returns table structure information (column names, types, constraints) similar to SQL's SHOW COLUMNS or DESCRIBE commands. It is a read-only operation with no side effects, no code execution, and no data modification. The low severity reflects minimal risk even if misused by an agent, as it only exposes schema metadata that is typically non-sensitive or already discoverable through other means.

From the tool's definition Tool name 'describe_table' and description 'Describe table structure (same as SHOW COLUMNS)' indicate a schema inspection operation that retrieves metadata without modifying data.

  "tools": {
