Create a new appointment/booking in GoHighLevel
AI agents use create_appointment to create or update resources in GoHighLevel MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GoHighLevel MCP Server environment.
This tool creates a new appointment/booking record in the CRM system. This is a reversible Write operation—appointments can be modified or deleted. While it has side effects (scheduling a slot, potentially triggering notifications), it does not execute arbitrary code, delete data irreversibly, or move money.

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 create_appointment:
{
"version": "1",
"default": "deny",
"tools": {
"create_appointment": {
"limits": [
{
"counter": "create_appointment_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_appointment stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
