THE RISK

Why omniwire_service_control needs a policy

Controlling systemd services is an Execute-level action: it triggers external operations on remote nodes (start/stop/restart/enable/disable services). Misuse by an AI agent could take down critical services across distributed infrastructure, giving it high severity. It does not directly delete data (so not Destructive), but stopping services can cause outages and is not easily reversible in all cases.

From the tool's definition 'Control systemd services on a node' — starting, stopping, restarting, or disabling system services on remote infrastructure nodes

POLICY

How to control omniwire_service_control

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_service_control:

policy.json

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

omniwire_service_control 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_service_control

What does the omniwire_service_control tool do? +

Control systemd services on a node. 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_service_control? +

Register the OmniWire MCP server in PolicyLayer and add a rule for omniwire_service_control: 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_service_control? +

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

Can I rate-limit omniwire_service_control? +

Yes. Add a rate_limit block to the omniwire_service_control 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_service_control completely? +

Set action: deny in the PolicyLayer policy for omniwire_service_control. 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_service_control? +

omniwire_service_control 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.
