Why omniwire_update needs a policy

This tool updates the OmniWire software itself and can propagate those updates across all mesh nodes. Pushing software updates to distributed infrastructure nodes is an Execute-level action with high blast radius — a misused or malicious update could compromise the entire mesh.

From the tool's definition self-update OmniWire...push updates to all mesh nodes

How to control omniwire_update

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_update:

policy.json

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

omniwire_update 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_update

What does the omniwire_update tool do? +

Check for updates, self-update OmniWire, manage auto-updates, and push updates to all mesh nodes. Sources: npm + GitHub releases. 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_update? +

Register the OmniWire MCP server in PolicyLayer and add a rule for omniwire_update: 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_update? +

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

Can I rate-limit omniwire_update? +

Yes. Add a rate_limit block to the omniwire_update 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_update completely? +

Set action: deny in the PolicyLayer policy for omniwire_update. 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_update? +

omniwire_update 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.
