Why certificate_local_list needs a policy

This tool performs a query/list operation on local certificates, which is a read-only action that retrieves data from the FortiOS device without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal—an attacker could enumerate certificates but cannot alter them or trigger system operations. This is a standard Read category tool.

From the tool's definition Tool name 'certificate_local_list' and description 'List local (device) certificates' indicate a read-only operation that retrieves certificate data without modification or side effects.

POLICY

How to control certificate_local_list

PolicyLayer is an MCP gateway — it sits between your AI agents and FortiOS 7 6 X MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for certificate_local_list:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "certificate_local_list": {}
  }
}

certificate_local_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register FortiOS 7 6 X MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
