Why webfilter_urlfilter_list needs a policy

This tool queries and retrieves existing URL filter table configurations. It performs a read-only operation that returns data without creating, modifying, deleting, or executing any changes to the system. The blast radius is minimal—an agent listing URL filters cannot cause damage or unauthorized access beyond viewing existing security policy data.

From the tool's definition Tool name includes 'list' and description states 'List all URL filter tables', indicating a retrieval operation with no side effects.

POLICY

How to control webfilter_urlfilter_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 webfilter_urlfilter_list:

policy.json

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

webfilter_urlfilter_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.
