## Why update_appointment is rated Medium

This tool modifies appointment data within the CRM system but does not delete records (which would be Destructive) or execute arbitrary operations (which would be Execute). The change is reversible—appointments can be updated again or reverted. Given the CRM context and potential business impact of appointment changes affecting customer interactions and workflows, severity is medium rather than low.

From the tool's own definition: "Tool name 'update_appointment' and description 'Update an existing appointment in GoHighLevel' indicate modification of existing data (appointment records) in a reversible manner."

## Use case

AI agents use update_appointment 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.
