WHAT IT DOES

What remove_coupon does on instantKOM MCP Server

AI agents use remove_coupon to create or update resources in instantKOM MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your instantKOM MCP Server environment.

RISK

Why remove_coupon is rated Medium

Removing a coupon reverses/undoes an applied discount, which is a modification of state. While it could be seen as destructive, coupons can typically be re-applied, making this reversible. It touches financial settings but doesn't move money or commit financial obligations directly — it just removes a discount code.

RECOMMENDED RULE

The rule that runs remove_coupon safely

remove_coupon Rate-limited

remove_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.
