## Why update_coupon is rated Medium

This tool modifies coupon records in the GoHighLevel CRM system. Updates are typically reversible (can be changed again), and the operation affects business data rather than triggering external actions or deleting records. However, coupon modifications could impact pricing, promotions, and revenue if misused, warranting medium severity. The tool belongs to the Write category as it creates or modifies data reversibly.

From the tool's own definition: "Tool name is 'update_coupon' and description states 'Update an existing coupon', indicating modification of existing coupon data in a reversible manner."

## Use case

AI agents use update_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.
