WHAT IT DOES

What update_phone_number does on GoHighLevel MCP Server

AI agents use update_phone_number 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 update_phone_number is rated Medium

This tool modifies contact or account phone number data within the GoHighLevel CRM system. Update operations are reversible—a phone number can be changed again if needed. While this affects CRM records used for communications/lead management (medium blast radius if misused in bulk or to wrong contacts), it does not execute arbitrary code, trigger financial transactions, or permanently destroy data.

From the tool's definition Tool name is 'update_phone_number' and description states 'Update phone number settings'. The verb 'update' indicates modification of existing data in a reversible manner.
