RISK

Why oauth_user_create is rated Medium

This tool creates new user accounts in an OAuth system, which is a write operation that modifies authentication state. While account creation is theoretically reversible (accounts can be deleted), the primary action is data creation. It is not Destructive because creation itself is not irreversible in the strict sense, and it is not Financial.

From the tool's definition Tool name 'oauth_user_create' and description 'Create a new OAuth user with a scrypt-hashed password' indicate irreversible creation of a new authentication identity.

RECOMMENDED RULE

The rule that runs oauth_user_create safely

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

oauth_user_create Rate-limited

oauth_user_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 Yaver, apply this rule, and every oauth_user_create call is checked against it from then on.
