Create a new opportunity in GoHighLevel CRM
AI agents use create_opportunity 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 new records in a CRM system, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. The severity is medium because misuse could create fraudulent or unwanted opportunities, pollute the CRM with spam leads, or disrupt sales processes, but the impact is limited to data creation which can be reviewed and cleaned up.
From the tool's definition Tool name 'create_opportunity' with description 'Create a new opportunity in GoHighLevel CRM' explicitly performs a create operation that adds new data (a sales opportunity) to the CRM system.
Documented attack patterns abuse exactly the kind of access create_opportunity 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_opportunity:
{
"version": "1",
"default": "deny",
"tools": {
"create_opportunity": {
"limits": [
{
"counter": "create_opportunity_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_opportunity 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.
