WHAT IT DOES

What omniwire_cdp does on OmniWire

AI agents invoke omniwire_cdp 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_cdp needs a policy

This tool runs a persistent headless browser capable of executing arbitrary JavaScript (code execution), intercepting network traffic (man-in-the-middle capability), manipulating cookies (session hijacking risk), and performing UI actions. It spans Execute and potential data exfiltration vectors.

From the tool's definition evaluate JS, click, type, network intercept, set-cookies, clear — persistent headless browser that can navigate, execute arbitrary JavaScript, intercept network traffic, and manipulate cookies across sessions

POLICY

How to control omniwire_cdp

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_cdp:

policy.json

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

omniwire_cdp 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_cdp

What does the omniwire_cdp tool do? +

Chrome DevTools Protocol — persistent headless browser via Docker container. Navigate, screenshot, HTML, PDF, cookies, evaluate JS, click, type, wait, network intercept, set-cookies, clear. Reuses pages across calls for speed. 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_cdp? +

Register the OmniWire MCP server in PolicyLayer and add a rule for omniwire_cdp: 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_cdp? +

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

Can I rate-limit omniwire_cdp? +

Yes. Add a rate_limit block to the omniwire_cdp 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_cdp completely? +

Set action: deny in the PolicyLayer policy for omniwire_cdp. 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_cdp? +

omniwire_cdp 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.
