WHAT IT DOES

What create_meta_field does on Fortimanager

AI agents use create_meta_field 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_meta_field is rated Medium

The 'create_meta_field' name clearly indicates data creation/modification (Write category). Given the FortiManager context (network/security device management), creating metadata fields could affect configuration metadata across managed devices. This is reversible (Write, not Destructive) but the lack of description lowers confidence.

From the tool's definition Tool name 'create_meta_field' indicates creation of metadata fields; no description provided to clarify scope or reversibility.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_meta_field 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_meta_field, this is the rule to start with:

create_meta_field Rate-limited

create_meta_field 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.
