WHAT IT DOES

What mysql_user_roles does on Mysql Mcp

AI agents call mysql_user_roles 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_user_roles is rated Low

This tool retrieves and displays existing role assignments for a user in MySQL. It performs a read-only query that does not modify, delete, or execute any operations—it merely lists data. The blast radius of misuse is minimal; an attacker would only gain visibility into role configurations, not the ability to modify permissions or access data beyond what is already accessible.

From the tool's definition Tool name 'mysql_user_roles' and description 'List roles assigned to a user' indicate a query/retrieval operation with no side effects.

RECOMMENDED RULE

The rule that runs mysql_user_roles safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mysql Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mysql_user_roles, this is the rule to start with:

mysql_user_roles Allowed

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