WHAT IT DOES

What omniwire_vpn does on OmniWire

AI agents invoke omniwire_vpn to trigger actions in OmniWire. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

THE RISK

High Risk

Why omniwire_vpn needs a policy

This tool actively manages VPN configurations and network connectivity across distributed mesh nodes. It triggers external operations (connecting/disconnecting VPN tunnels, changing routing, enabling kill-switches) whose effects depend on arguments.

From the tool's definition Manage VPN on mesh nodes (Mullvad/OpenVPN/WireGuard/Tailscale)... multi-hop, DAITA, quantum-resistant tunnels, DNS-over-HTTPS, obfuscation, kill-switch

POLICY

How to control omniwire_vpn

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "omniwire_vpn": {
      "limits": [
        {
          "counter": "omniwire_vpn_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

omniwire_vpn stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about omniwire_vpn

What does the omniwire_vpn tool do? +

Manage VPN on mesh nodes (Mullvad/OpenVPN/WireGuard/Tailscale). Mesh-safe: split-tunnel or namespace isolation. Mullvad advanced: multi-hop, DAITA, quantum-resistant tunnels, DNS-over-HTTPS, obfuscation, kill-switch. It is categorised as a Execute tool in the OmniWire MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on omniwire_vpn? +

Register the OmniWire MCP server in PolicyLayer and add a rule for omniwire_vpn: 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 OmniWire. Nothing to install.

What risk level is omniwire_vpn? +

omniwire_vpn is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit omniwire_vpn? +

Yes. Add a rate_limit block to the omniwire_vpn 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.

How do I block omniwire_vpn completely? +

Set action: deny in the PolicyLayer policy for omniwire_vpn. 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.

What MCP server provides omniwire_vpn? +

omniwire_vpn is provided by the OmniWire MCP server (voidchecksum/omniwire). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every OmniWire tool call.

Start from OmniWire, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
