WHAT IT DOES

What mysql_role_grant does on Mysql Mcp

AI agents use mysql_role_grant 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_grant is rated Medium

Granting privileges to a role modifies access control configuration in the database. This is a Write operation (it changes permission state) but not Destructive (it can be revoked). However, it has high severity because misuse could escalate privileges, granting unauthorized access to sensitive data or destructive capabilities to roles that shouldn't have them.

RECOMMENDED RULE

The rule that runs mysql_role_grant 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_grant, this is the rule to start with:

mysql_role_grant Rate-limited

mysql_role_grant 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.
