WHAT IT DOES

What proxysql_query_rules does on Mysql Mcp

AI agents call proxysql_query_rules 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 proxysql_query_rules is rated Low

The tool performs a read-only query against the mysql_query_rules table to display ProxySQL routing configuration. It retrieves and presents existing data without modifying, deleting, or executing anything. This is a low-severity informational query suitable for auditing or understanding routing behavior.

From the tool's definition Tool description states 'List query routing rules' with 'Shows rule IDs, match patterns, destination hostgroups, and cache settings' — indicative of a retrieval/inspection operation with no side effects.
