WHAT IT DOES

What mysql_role_create does on Mysql Mcp

AI agents use mysql_role_create to create or update resources in Mysql Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mysql Mcp environment.

RISK

Why mysql_role_create is rated Medium

This tool creates a new role in MySQL, which is a reversible modification of database authorization state. While not destructive (roles can be deleted), it modifies security configuration. Severity is high because creating roles can grant unintended permissions to users, potentially escalating privileges or creating backdoors if an AI agent misuses it without proper validation.

From the tool's definition Tool name 'mysql_role_create' and description 'Create a new role' indicate creation of a new database role object.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs mysql_role_create 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_role_create, this is the rule to start with:

mysql_role_create Rate-limited

mysql_role_create stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Mysql Mcp, apply this rule, and every mysql_role_create call is checked against it from then on.
