WHAT PILOT_TAB_NEW ON PILOT DOES

AI agents invoke pilot_tab_new to trigger actions in Pilot. 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

Opening a new browser tab and optionally navigating to a URL constitutes executing a browser operation whose effects depend on the URL argument. While not as severe as directly executing arbitrary code, it represents the ability to navigate to potentially malicious sites, trigger unwanted downloads, or chain with other pilot tools to perform harmful actions.

From the tool's definition Tool description states it 'Open[s] a new browser tab' and can navigate to a URL, which are browser automation actions that trigger external operations (Chromium instance control via Playwright).

HOW TO CONTROL PILOT_TAB_NEW

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

policy.json

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

pilot_tab_new 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 Pilot — 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 pilot_tab_new tool do? +

Open a new browser tab, optionally navigating to a URL. Use when the user wants to open a link in a new tab, create a blank tab, or work with multiple pages simultaneously. Parameters: - url: Optional URL to navigate to in the new tab (omit for a blank about:blank tab) Returns: The new tab. It is categorised as a Execute tool in the Pilot MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on pilot_tab_new? +

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

What risk level is pilot_tab_new? +

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

Can I rate-limit pilot_tab_new? +

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

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

pilot_tab_new is provided by the Pilot MCP server (tacosyhorchata/pilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Pilot tool call.
