AI agents call list_fabric_connectors to retrieve information from Fortimanager without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list_' prefix indicates a retrieval operation that queries existing fabric connectors without modification or execution. This is a standard read operation on FortiManager infrastructure. The low severity reflects that querying connector information poses minimal risk, though confidence is moderately reduced due to the empty description.
From the tool's definition Tool name 'list_fabric_connectors' uses the verb 'list', which retrieves and queries data. No description is provided, but the naming pattern is consistent with read-only operations across the FortiManager API.
Documented attack patterns abuse exactly the kind of access list_fabric_connectors gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Fortimanager, and nothing reaches the server without passing your rules. This is the rule we recommend for list_fabric_connectors:
{
"version": "1",
"default": "deny",
"tools": {
"list_fabric_connectors": {}
}
}list_fabric_connectors is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_fabric_connectors. It is categorised as a Read tool in the Fortimanager MCP Server, which means it retrieves data without modifying state.
Register the Fortimanager MCP server in PolicyLayer and add a rule for list_fabric_connectors: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Fortimanager. Nothing to install.
list_fabric_connectors is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_fabric_connectors rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_fabric_connectors. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_fabric_connectors is provided by the Fortimanager MCP server (jmpijll/fortimanager-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Fortimanager, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
