Why webfilter_content_list needs a policy

This tool performs a simple list/query operation on firewall web filter configurations. It has no side effects, does not modify data, and does not execute code or delete resources. The blast radius is minimal as it only exposes existing configuration data that a user with appropriate access would already have visibility to.

From the tool's definition Tool name 'webfilter_content_list' and description 'List all web content filter (keyword) tables' indicate a read-only query operation that retrieves and enumerates existing filter configurations without modification.

POLICY

How to control webfilter_content_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_content_list:

policy.json

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

webfilter_content_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.
