WHAT CREATE_TAB ON CAMOFOX DOES

AI agents invoke create_tab to trigger actions in Camofox. 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

This tool triggers an external browser operation (opening a new tab with stealth fingerprinting via the CamoFox REST API). It initiates a browser session/context with potential for further automation actions, which qualifies as Execute. The anti-detection/stealth capability adds risk since it could be used to bypass bot detection systems.

From the tool's definition Create a new browser tab with anti-detection fingerprinting. Each tab gets a unique fingerprint. Optionally provide a URL, userId, sessionKey, and viewport.

Documented attack patterns abuse exactly the kind of access create_tab gives an agent:

HOW TO CONTROL CREATE_TAB

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

policy.json

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

create_tab 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 Camofox — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the create_tab tool do? +

Create a new browser tab with anti-detection fingerprinting. Each tab gets a unique fingerprint. Optionally provide a URL, userId, sessionKey, and viewport. To share the camofox CLI default browser profile/context, pass userId \. It is categorised as a Execute tool in the Camofox MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on create_tab? +

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

What risk level is create_tab? +

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

Can I rate-limit create_tab? +

Yes. Add a rate_limit block to the create_tab 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 create_tab completely? +

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

create_tab is provided by the Camofox MCP server (redf0x1/camofox-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Camofox tool call.
