cancel_scheduled_campaign_message

THE RISK

Critical Risk

Cancelling a scheduled campaign message cannot be undone; once cancelled, that specific scheduled send is permanently removed. While it doesn't delete data records, it irreversibly aborts a pending operation. Severity is medium because it affects outbound messaging for a single contact rather than bulk data or financial records.

From the tool's definition 'Cancel a scheduled campaign message' - cancelling a scheduled message is an irreversible action that permanently removes the pending delivery of that message

HOW TO CONTROL CANCEL_SCHEDULED_CAMPAIGN_MESSAGE

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 cancel_scheduled_campaign_message:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "cancel_scheduled_campaign_message"
  ]
}

cancel_scheduled_campaign_message disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
