AI agents use create_invoice_schedule 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 invoice schedule, which is a Write operation (creating a new resource). While it relates to financial billing, it does not directly move money or commit an immediate financial obligation — it sets up a schedule for future invoices.
From the tool's definition 'Create a new invoice schedule' — creates a recurring financial billing schedule
Documented attack patterns abuse exactly the kind of access create_invoice_schedule gives an agent:
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_invoice_schedule:
{
"version": "1",
"default": "deny",
"tools": {
"create_invoice_schedule": {
"limits": [
{
"counter": "create_invoice_schedule_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_invoice_schedule 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.

Yes. Add a rate_limit block to the create_invoice_schedule 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.
Set action: deny in the PolicyLayer policy for create_invoice_schedule. 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.
