THE RISK

High Risk

This tool executes a business process with broad effects—it will send messages to potentially many contacts and trigger automated workflows. While not immediately financial or destructive, the blast radius of misconfiguration (e.g., launching to the wrong audience, with wrong messaging) is significant.

From the tool's definition The tool 'start_campaign' launches a campaign, which triggers automated messaging and business operations.

HOW TO CONTROL START_CAMPAIGN

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

policy.json

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

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