THE RISK

Low Risk

Why listSiteToSiteVpns needs a policy

This is a read-only operation that retrieves sensitive network infrastructure details (VPN tunnels, IP addresses, subnets, protocols). While no data is modified, the severity is elevated to 'high' because exposing VPN configuration details to an AI agent could enable reconnaissance attacks, IP spoofing, or lateral movement planning if the agent is compromised or misaligned.

From the tool's definition The tool 'listSiteToSiteVpns' explicitly lists VPN configurations including tunnel names, IPs, status, protocols, and subnet information.

POLICY

How to control listSiteToSiteVpns

PolicyLayer is an MCP gateway — it sits between your AI agents and Tplink Omada, and nothing reaches the server without passing your rules. This is the rule we recommend for listSiteToSiteVpns:

policy.json

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

listSiteToSiteVpns 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 Tplink Omada — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
