WHAT IT DOES

What mysql_role_assign does on Mysql Mcp

AI agents use mysql_role_assign 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_assign is rated Medium

This tool creates or modifies user role assignments, which is a write operation that changes database state. While it doesn't delete data, assigning roles can grant or alter privileges, making it a high-severity write operation. An AI agent misusing this could accidentally escalate privileges, grant inappropriate access, or create security gaps.

From the tool's definition Tool name 'mysql_role_assign' and description 'Assign a role to a user' indicate modification of database access control and user permissions.

RECOMMENDED RULE

The rule that runs mysql_role_assign 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_assign, this is the rule to start with:

mysql_role_assign Rate-limited

mysql_role_assign 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.
