WHAT IT DOES

What create_traffic_class does on Fortimanager

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

RISK

Why create_traffic_class is rated Medium

The tool creates (writes) a new traffic class, which is a reversible configuration change. While it modifies security/network settings, it does not execute arbitrary code, delete data, or move money. The severity is medium because misuse could affect network traffic prioritization and QoS policies, but the blast radius is limited to traffic classification rules and is reversible.

From the tool's definition Tool name 'create_traffic_class' and description 'Create a traffic class' indicate data creation. This is a write operation that adds a new traffic class configuration to FortiManager.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_traffic_class safely

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

create_traffic_class Rate-limited

create_traffic_class 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 Fortimanager, apply this rule, and every create_traffic_class call is checked against it from then on.
