Why omniwire_metrics needs a policy

This tool retrieves and queries metrics data from infrastructure nodes for monitoring purposes. It has no side effects on the system, does not execute commands, does not modify or delete data, and does not involve financial operations. It is purely informational/observational in nature, making it a Read category tool with low severity.

From the tool's definition Tool description states it 'Collect and export Prometheus-compatible metrics from mesh nodes. Scrape returns current values; export formats as Prometheus text exposition.' The verbs 'collect', 'scrape', and 'export' indicate read-only retrieval of monitoring…

POLICY

How to control omniwire_metrics

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_metrics:

policy.json

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

omniwire_metrics 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 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_metrics

What does the omniwire_metrics tool do? +

Collect and export Prometheus-compatible metrics from mesh nodes. Scrape returns current values; export formats as Prometheus text exposition. It is categorised as a Read tool in the OmniWire MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on omniwire_metrics? +

Register the OmniWire MCP server in PolicyLayer and add a rule for omniwire_metrics: 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_metrics? +

omniwire_metrics is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit omniwire_metrics? +

Yes. Add a rate_limit block to the omniwire_metrics 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_metrics completely? +

Set action: deny in the PolicyLayer policy for omniwire_metrics. 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_metrics? +

omniwire_metrics 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.
