WHAT IT DOES

What create_coupon does on GoHighLevel MCP Server

AI agents use create_coupon 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.

RISK

Why create_coupon is rated Medium

This tool creates a new coupon, which is a reversible write operation. While coupons can affect business finances (discounts issued), the tool itself only creates the coupon record without executing financial transactions or charging customers. The severity is medium because misuse could create excessive coupons that undermine business revenue strategy, but the action is reversible (coupons can be deleted/modified).

From the tool's definition Tool name 'create_coupon' and description 'Create a new promotional coupon' indicate creation of new data (a coupon record) in the GoHighLevel CRM system.

RECOMMENDED RULE

The rule that runs create_coupon safely

create_coupon Rate-limited

create_coupon 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.
