WHAT IT DOES

What mysql_slow_queries does on Mysql Mcp

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

RISK

Why mysql_slow_queries is rated Low

This tool queries MySQL's performance_schema to retrieve diagnostic information about slow queries. It performs passive inspection of existing performance metrics without creating, modifying, or deleting any data. The blast radius of misuse is minimal: an attacker could learn about query performance patterns but cannot execute arbitrary queries, modify data, or cause destructive operations.

From the tool's definition Tool retrieves slow queries from performance_schema—a read-only diagnostic table in MySQL. Description uses "Get" indicating data retrieval with no modification.
